A First: NASA Spots Single Methane Leak from Space

Atmospheric methane is a potent greenhouse gas, but the percentage of it produced through human activities is still poorly understood. Future instruments on orbiting satellites can help address this issue by surveying human-produced methane emissions. Recent data from the Aliso Canyon event, a large accidental methane release near Porter Ranch, California, demonstrates this capability. The Hyperion imaging spectrometer onboard NASA's EO-1 satellite successfully detected this release event on three different overpasses during the winter of 2015-2016. This is the first time the methane plume from a single facility has been observed from space. The orbital observations were consistent with airborne measurements. This image pair shows a comparison of detected methane plumes over Aliso Canyon, California, acquired 11 days apart in Jan. 2016 by: (left) NASA's AVIRIS instrument on a NASA ER-2 aircraft at 4.1 miles (6.6 kilometers) altitude and (right) by the Hyperion instrument on NASA's Earth Observing-1 satellite in low-Earth orbit. The additional red streaks visible in the EO-1 Hyperion image result from measurement noise -- Hyperion was not specifically designed for methane sensing and is not as sensitive as AVIRIS-NG. Additionally, the EO-1 satellite's current orbit provided poor illumination conditions. Future instruments with much greater sensitivity on orbiting satellites can survey the biggest sources of human-produced methane around the world. http://photojournal.jpl.nasa.gov/catalog/PIA20716

$California, reveals the devastating effect of California's ongoing drought on Sierra Nevada conifer forests. The map will be used to help the U.S. Forest Service assess and respond to the impacts of increased tree mortality caused by the drought, particularly where wildlands meet urban areas within the Sierra National Forest. After several years of extreme drought, the highly stressed conifers (trees or bushes that produce cones and are usually green year-round) of the Sierra Nevada are now more susceptible to bark beetles (Dendroctonus spp.). While bark beetles killing trees in the Sierra Nevada is a natural phenomenon, the scale of mortality in the last couple of years is far greater than previously observed. The U.S. Forest Service is using recent airborne spectroscopic measurements from NASA's Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) instrument aboard NASA's ER-2 aircraft, together with new advanced algorithms, to quantify this impact over this large region of rugged terrain. The high-altitude ER-2 aircraft is based at NASA's Armstrong Flight Research Center, Edwards, California. The image was created by scientists at the USFS's Pacific Southwest Region Remote Sensing Lab, McClellan, California, by performing a time series analysis of AVIRIS images. Scientists evaluated baseline tree mortality on public lands in the summer of 2015 using a machine learning algorithm called "random forest." This algorithm classifies the AVIRIS measurements as dominated by either shrubs, healthy trees or newly dead conifer trees. To quantify how much the amount of dead vegetation increased during the fall of 2015, the Forest Service scientists conducted an advanced spectral mixture analysis. This analysis evaluates each spectrum to determine the fraction of green vegetation, dead vegetation and soil. The full spectral range of AVIRIS is important to separate the signatures of soil and dead vegetation. To produce this comprehensive Sierra National Forest tree mortality map, the result from the summer of 2015 was evaluated to look for increases of more than 10 percent in dead vegetation during the fall of 2015. AVIRIS measures spectra of the Earth system to conduct advanced science research. These western U.S. AVIRIS measurements were acquired as part of NASA's Hyperspectral Infrared Imager (HyspIRI) preparatory airborne campaign. HyspIRI was one of the space missions suggested to NASA by the National Academy of Sciences in its 2007 decadal survey for Earth Science. In the future, HyspIRI could provide spectral and thermal measurements of this type globally for ecosystem research and additional science objectives. http://photojournal.jpl.nasa.gov/catalog/PIA20717$

Multiple Aspects of the Southern California Wildfires as Seen by NASA's AVIRIS

NASA's Airborne Visible Infrared Imaging Spectrometer instrument (AVIRIS), flying aboard a NASA Armstrong Flight Research Center high-altitude ER-2 aircraft, observed wildfires burning in Southern California on Dec. 5-7, 2017. AVIRIS is an imaging spectrometer that observes light in visible and infrared wavelengths, measuring the full spectrum of radiated energy. Unlike regular cameras with three colors, AVIRIS has 224 spectral channels, measuring contiguously from the visible through the shortwave infrared. Data from these flights, compared against measurements acquired earlier in the year, show many ways this one instrument can improve both our understanding of fire risk and the response to fires in progress. The top row in this image compilation shows pre-fire data acquired from June 2017. At top left is a visible-wavelength image similar to what our own eyes would see. The top middle image is a map of surface composition based on analyzing the full electromagnetic spectrum, revealing green vegetated areas and non-photosynthetic vegetation that is potential fuel as well as non-vegetated surfaces that may slow an advancing fire. The image at top right is a remote measurement of the water in tree canopies, a proxy for how much moisture is in the vegetation. The bottom row in the compilation shows data acquired from the Thomas fire in progress in December 2017. At bottom left is a visible wavelength image. The bottom middle image is an infrared image, with red at 2,250 nanometers showing fire energy, green at 1,650 nanometers showing the surface through the smoke, and blue at 1,000 nanometers showing the smoke itself. The image at bottom right is a fire temperature map using spectroscopic analysis to measure fire thermal emission recorded in the AVIRIS spectra. https://photojournal.jpl.nasa.gov/catalog/PIA22194

$NASA's Airborne Visible Infrared Imaging Spectrometer instrument (AVIRIS), flying aboard a NASA Armstrong Flight Research Center high-altitude ER-2 aircraft, flew over the wildfires burning in Southern California on Dec. 5, 2017 and acquired this false-color image. Active fires are visible in red, ground surfaces are in green and smoke is in blue. AVIRIS is an imaging spectrometer that observes light in visible and infrared wavelengths, measuring the full spectrum of radiated energy. Unlike regular cameras with three colors, AVIRIS has 224 spectral channels from the visible through the shortwave infrared. This permits mapping of fire temperatures, fractional coverage, and surface properties, including how much fuel is available for a fire. Spectroscopy is also valuable for characterizing forest drought conditions and health to assess fire risk. AVIRIS has been observing fire-prone areas in Southern California for many years, forming a growing time series of before/after data cubes. These data are helping improve scientific understanding of fire risk and how ecosystems respond to drought and fire. https://photojournal.jpl.nasa.gov/catalog/PIA11243$
