Background: In July 2014, NASA selected proposals from the second Earth Venture Instrument (EVI-2) Pathfinder Program for two new instruments that will observe changes in global vegetation from the International Space Station. The sensors will give scientists new ways to see how forests and ecosystems are affected by changes in climate or land use change. 1) 2) 3)

The new projects are:

GEDI (Global Ecosystem Dynamics Investigation), a laser-based system from the University of Maryland, College Park, to observe the structure of forest canopy. This instrument is expected to be launched in 2019.

- Ralph Dubayah, of the University of Maryland, is the principal investigator for the GEDI Lidar. This project will use a laser-based system to study a range of climates, including the observation of the forest canopy structure over the tropics, and the tundra in high northern latitudes. This data will help scientists better understand the changes in natural carbon storage within the carbon cycle from both human-influenced activities and natural climate variations.

- The GEDI team has extensive experience in observing and modeling forest and vegetation dynamics. Dubayah has led numerous vegetation lidar observations from sub-orbital platforms throughout his career. The team includes partnerships with NASA's Goddard Space Flight Center, Greenbelt, Maryland; Woods Hole Research Center, Woods Hole, Massachusetts; the U.S. Forest Service, Ogden, Utah; and Brown University, Providence, Rhode Island.

ECOSTRESS (ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station), a high-resolution multiple wavelength imaging spectrometer from NASA/JPL (Jet Propulsion Laboratory) in Pasadena, CA, to study the effectiveness of water use by vegetation.

- Simon Hook of JPL is the PI (Principal Investigator) for ECOSTRESS. This project will use a high-resolution thermal infrared radiometer to measure plant evapotranspiration, the loss of water from growing leaves and evaporation from the soil. These data will reveal how ecosystems change with climate and provide a critical link between the water cycle and effectiveness of plant growth, both natural and agricultural.

- The ECOSTRESS team has extensive experience in development and analysis of thermal infrared spectroscopic images of the Earth's surface. Hook has served as project scientist for the ASTER (Advanced Spaceborne Thermal Emission Reflection Radiometer) instrument on NASA's Earth Observing System Terra satellite and has been involved in numerous sub-orbital field campaigns. The team includes partnerships with the U.S. Department of Agriculture, Beltsville, Maryland, and Maricopa, Arizona; Princeton University, Princeton, New Jersey; and University of Idaho, Moscow, Idaho.

The International Space Station provides several in-orbit capabilities useful to both instruments. The space station orbit is inclined relative to the poles, providing more observation time of forests and vegetation over temperate land masses than possible from the polar orbits commonly used for other types of Earth observations. The GEDI laser requires significant power resources, which the space station can provide. Also, the relatively low altitude of the station's orbit, about 400 km up, benefits GEDI by ensuring a higher return energy for laser pulses reflected from the ground.

NASA/LaRC (Langley Research Center) in Hampton, Virginia, manages the Earth System Science Pathfinder program for NASA's Science Mission Directorate. The missions in this program provide an innovative approach to address Earth science research with periodic windows of opportunity to accommodate new scientific priorities.

The NASA ECOSTRESS mission is one of two instruments chosen from the second EVI-2 (Earth Venture Instrument) Pathfinder Program AO (Announcement of Opportunity). With a launch scheduled for 2018, ECOSTRESS will assess vegetation water stress using a multispectral thermal instrument installed on the International Space Station. In the ISS orbit of ~ 400 km altitude and 51.6º inclination, ECOSTRESS will provide a repeat cycle of nearly three-days and a spatial resolution of ~ 60 m. Due to the unique orbital path of the ISS, ECOSTRESS will observe the same spot on Earth at different times each day. This configuration will enable an unprecedented view of diurnal trends in vegetation evapotranspiration, allowing the science community to address the following questions: 4) 5) 6)

• How does the terrestrial biosphere respond to changes in water availability?

• How do evapotranspiration and vegetation water stress interact with the global carbon cycle?

• How can scientists better understand agricultural vulnerabilities and drought impacts linked to vegetation water stress?

The ECOSTRESS mission will answer these questions by accurately measuring the temperature of plants. Plants regulate their temperature by releasing water through tiny pores on their leaves called stomata. If they have sufficient water they can maintain their temperature but if there is insufficient water their temperatures rise and this temperature rise can be measured with a sensor in space. ECOSTRESS will use a multispectral thermal infrared radiometer to measure the surface temperature that will be delivered to Houston for deployment on the International Space Station in 2018. The radiometer will acquire the most detailed temperature images of the surface ever acquired from space and will be able to measure the temperature of an individual farmers field.

One of the core products that will be produced by ECOSTRESS team is ESI (Evaporative Stress Index). ESI is a leading drought indicator - it can indicate that plants are stressed and that a drought is likely to occur providing the option for decision makers to take action. Figure 3 illustrates the ESI for the United States during the 2012 drought. The red areas indicate regions of high water stress.

ECOSTRESS instrument

Simon J. Hook of NASA/JPL is the PI of the ECOSTRESS instrument development and science investigation. The mission leverages the successful design, construction, and testing of the PHyTIR (Prototype HyspIRI Thermal Infrared Radiometer), which was initially developed to support testing and assessment for the HyspIRI (Hyperspectral Infrared Imager) under the auspices of ESTO (Earth Science Technology Office). ECOSTRESS consists of a cross-track, push-whiskbroom, scanning, multiband filter radiometer with five spectral bands between 8 and 12.5 µm, and a high spatial resolution of 38 m in-track by 69 m cross-track, and will be deployed on the JEM (Japanese Experiment Module) External Facility on the ISS. Because of the precessing orbit of the ISS, the ECOSTRESS will enable vegetation water stress assessments on a diurnal scale. 7)

The multispectral TIR (Thermal Infrared) instrument, mounted on the JEM-EF , will measure the brightness temperature of plants and use that information to better understand how much water plants need and how they respond to stress (evapotranspiration dynamics).

The ECOSTRESS instrument has a mass of ~465 kg, an average power consumption of ~527 W, a volume of 1.3 m3, an average data rate of 2.3 Mbit/s (nominally 4.5 Mbit/s) and a design life of 5 years. Typical revisit of 90% of CONUS every 4 days at varying times over the diurnal cycle.

The TIR instrument will acquire data from the ISS with a 38 m in-track by 68 m cross-track spatial resolution in five spectral bands, located in the TIR part of the electromagnetic spectrum between 8 and 12.5 µm. The positions of three of the TIR bands closely match the first three thermal bands of ASTER, while two of the TIR bands match bands of ASTER and MODIS typically used for split-window type applications (ASTER bands 12–14 and MODIS bands 31, 32). It is expected that small adjustments to the band positions will be made based on ongoing engineering filter performance capabilities. 10)

The TIR instrument will operate as a push-whisk mapper, similar to MODIS but with 256 pixels in the cross-whisk direction for each spectral channel (Figure 4), which enables a wide swath and high spatial resolution. As the ISS moves forward, the scan mirror sweeps the focal plane ground projection in the cross-track direction. Each sweep is 256-pixels wide. The different spectral bands are swept across a given point on the ground sequentially. From the 400±25 km ISS altitude, the resulting swath is 402 km wide. A wide continuous swath is produced even with an ISS yaw of up to ±18.5º. The scan mirror rotates at a constant angular speed. It sweeps the focal plane image 53º across nadir, then to two on-board blackbody targets at 300 K and 340 K. Both blackbodies will be viewed with each cross-track sweep every 1.29 seconds to provide gain and offset calibrations.

In summary, ECOSTRESS will provide the highest spatial resolution thermal infrared data ever from the International Space Sta1on. HyspIRI (Hyperspectral Infrared Imager) is planned for the 2023+ timeframe.

• ECOSTRESS is possible because of the development of the PHyTIR (Prototype HyspIRI Thermal Infrared Radiometer) instrument for HyspIRI-TIR supported by ESTO

• ECOSTRESS will address a subset of the science associated with HyspIRI

• The ECOSTRESS mission will help answer three key science questions:

- How is the terrestrial biosphere responding to changes in water availability?

- How do changes in diurnal vegetation water stress impact the global carbon cycle?

- Can agricultural vulnerability be reduced through advanced monitoring of agricultural water consumptive use and improved drought es1ma1on?

• ECOSTRESS has a clearly defined set of data products and mature algorithms

• Opportunity for combined HyspIRI-like datasets using the European EnMAP and ECOSTRESS with GEDI (Global Ecosystems Dynamics Investigation Lidar) for structure.


Development status:

• June 11, 2018: A new batch of science is headed to the International Space Station aboard the SpaceX Dragon on the company's 15th mission for commercial resupply services, scheduled for launch on 29 June from NASA's Kennedy Space Center in Florida. The spacecraft will deliver science that studies plant water use all over the planet, artificial intelligence, gut health in space, more efficient drug development and the formation of inorganic structures without the influence of Earth's gravity. 14)

• April 30, 2018: ORR (Operational Readiness Review) at JPL (Jet Propulsion Laboratory).

• April 17, 2018: The ECOSTRESS instrument arrived at Kennedy Space Center on 9 April to begin final preparations for launch to the International Space Station this summer aboard a cargo resupply mission. 15)

- ECOSTRESS is expected to provide key insights into how plants link Earth's global carbon and water cycles. ECOSTRESS data will be used in conjunction with other satellite and ground measurements, such as those from NASA's Orbiting Carbon Observatory-2 satellite. By doing this, scientists hope to understand more clearly the total amount of carbon dioxide plants remove from the atmosphere during a typical day. In addition, they hope to better identify which areas on the planet require more or less water for the amount of carbon dioxide they take up.

- In practical terms, the year of data gleaned from ECOSTRESS will be useful for agricultural water managers. This data should improve our understanding of how certain regions are affected by drought and help agricultural and water management communities better manage water use for agriculture. The high ground spatial resolution of ECOSTRESS data will be useful for research on the effects of drought on agriculture at the field-scale.

• May, 2016: JPL selected an upgraded Thales LPT9310 COTS (Commercial Off The Shelf) cryocooler for the ECOSTRESS instrument. The LPT9310's proven reliability has resulted in interest from JPL in using this cooler for cost-sensitive space applications. This instrument provides nominally over 4 W of cooling capacity at 80 K. - However, this capability has only been proven in terrestrial (commercial) applications. In order to provide sufficient justification for using an off-the-shelf cooler for a flight application, additional tests have been performed on the delivered flight coolers, to attain a sufficiently controlled level of quality while leveraging the heritage of the COTS cooler. 16)

- A qualification test campaign was completed successfully, with the upgraded design meeting qualification-level robustness requirements after being subjected to fatigue cycling as well as providing the required efficiency increase. Flight models are currently in production and will be delivered to JPL July 2016.

• UiTMSAT-1, a 1U CubeSat of Malaysia. JAXA arranged for the testing and the launch of the BIRDS-2 CubeSats to the ISS.



Mission status:

• September 18, 2018: NASA's ECOSTRESS captured new imagery of variations in surface-temperature patterns in Los Angeles County. The first of its kind to be taken by the agency's newest Earth-observing mission, it is more detailed than previous imagery and, unlike prior imagery, was acquired at different times of the day. 20)

- ECOSTRESS measures surface temperature — the temperature you would feel if you touched the surface of something — rather than the air temperature typically reported by weather stations. The images were acquired throughout the day between 22 July 22 and 14 August during an extended period of high temperatures in the Los Angeles area.

- Cooler temperatures appear in blue, and warmer temperatures are shown in red. In the image taken July 22 at 4:07 a.m., the hottest (reddest) areas are dark asphalt surfaces that are unshaded during the day and remain warm throughout the night. They include freeways, airports, oil refineries and parking lots. The cool (blue) areas are clouds and higher-elevation mountainous regions (dark blue).


Figure 13: ECOSTRESS captured surface temperature variations in Los Angeles, CA in the early morning hours of July 22. Hot areas are shown in red, warm areas in orange and yellow, and cooler areas in blue (image credit: NASA/JPL-Caltech)

- The other images show how different urban surfaces warm up and cool down throughout the day. The daytime image (upper left) acquired at 3:01 p.m. PDT on July 31 shows how hot the inland regions can get during a period of extreme heat. The Santa Anita racetrack parking lot was the hottest area. At 147.3° F, the surface temperature there was hot enough to fry an egg.


Figure 14: ECOSTRESS imagery shows surface temperature variations in Los Angeles, California between July 22 and August 14 at different times of day. Hot areas are shown in red, warm areas in orange and yellow, and cooler areas in blue (image credit: NASA/JPL-Caltech)

Legend to Figure 14: The images in the upper right, lower left and lower right — acquired at 9:26 p.m., 11:43 p.m. and 4:07 a.m., respectively — show how urban surfaces cool down, with roof surfaces cooling at a much faster rate than roads and other asphalt surfaces that have a higher heat capacity. Note that in the lower-right image, reds correspond with temperatures in the 80s. The top image from the same time shows a slightly different scale to enhance the contrast between different surfaces — and reds correspond with temperatures in the 70s.

The Los Angeles area is known for its Mediterranean climate and abundant sunshine but also for its extreme "micro-climate" temperature swings — from cooler coastal areas to much warmer inland regions like the San Gabriel Valley. ECOSTRESS can detect the distribution and pattern variations of that surface heat over areas the size of a football field.

• August 2, 2018: ECOSTRESS, NASA's new Earth-observing mission aboard the ISS, has captured new imagery of three wildfires burning in California and Nevada — the first image of its kind to be taken by the agency's newest Earth-observing mission. 21)

- Surface temperatures above 32 degrees Celsius are shown in red, highlighting the burning areas along the fire fronts. Zooming in on the Carr and Perry fires shows the heat data in more detail, and also the very distinct smoke plumes the fires are producing. The measurements have a ground resolution of 70 m by 70 m.

- The Carr Fire, one of the largest of more than a dozen fires burning in California,started on July 23. As of August 2, the fire had grown to over 121,000 acres (48966 hectares). The Whaleback Fire started near Spalding, California on July 27 and spanned nearly 19,000 acres (7690 hectares) on August 2. The Perry Fire, which started just north of Reno, Nevada on July 27, had engulfed more than 49,000 acres (19830 hectares) as of August 2.


Figure 15: This ECOSTRESS image, acquired on July 28, shows three wildfires burning in the western US (in red) — the Carr and Whaleback fires in California, and the Perry Fire in Nevada (image credit: NASA/JPL-Caltech)

• July 23, 2018: Just days after its successful installation on the International Space Station, NASA's newest Earth-observing mission, ECOSTRESS (ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station), has collected its first science data on Earth's surface temperature. 22)

- ECOSTRESS will measure the temperature of plants from space, enabling researchers to determine how much water plants use and to study how droughts affect plant health.

- The instrument was launched June 29 from Florida's Cape Canaveral Air Force Station on a SpaceX cargo resupply mission. It rode to orbit in the "trunk" of SpaceX's Dragon spacecraft, which berthed at the station on July 2. On July 5, ground controllers at NASA's Johnson Space Center in Houston extracted ECOSTRESS from the trunk, robotically transferred it to the station's Japanese Experiment Module - Exposed Facility (JEM-EF) and installed it. After a few days of testing and start-up activities, ECOSTRESS acquired its first-light image on 9 July.

- "Often satellite missions require weeks or months to produce data of the quality that we are already getting from ECOSTRESS," said the mission's principal investigator, Simon Hook of NASA's Jet Propulsion Laboratory in Pasadena, California. ECOSTRESS is one of a new class of low-cost, rapid-development NASA science instruments. The ECOSTRESS instrument was launched less than four years after the project was started.

- The ECOSTRESS team is now checking out the instrument and acquiring preliminary science data, a process expected to take about a month. They have completed an initial calibration of the science data and are now validating the data by comparing them with similar measurements made at ground control sites. When this process is complete, ECOSTRESS will be ready to begin its one-year science mission.

• July 6,2018: NASA's ECOSTRESS was removed from the Dragon spacecraft and robotically installed on the exterior of the space station's Japanese Experiment Module -Exposed Facility (JEM-EF) late Thursday, July 5. Functional testing is expected to begin next week (update of Ref. 17).
