NDVI-processed imagery taken by Landsat 9 OLI-2 in May 2022 of Bryce Canyon National Park and nearby urban area. Healthy vegetation are visualized as bright yellow, while stressed plants, bare earth, and urban areas approach dark red. The continuity of the Landsat program described vegetation response to pervasive drought conditions in Bryce Canyon which the National Park Service can use to when making conservation decisions.

We created an averaged seasonal Evaporative Stress Index (ESI) composite for fall 2020 in the west Tennessee region utilizing NASA’s ECOSTRESS sensor onboard the International Space Station. The ESI reveals areas where vegetation is stressed due to lack of water. Dark blue regions represent areas where vegetation is thriving, compared to the yellow areas, where vegetation is experiencing some water stress.​​

Google Earth Engine processed off-shore imagery in the Gulf of Mexico. The image was captured by NASA Earth observations satellite Landsat 9 OLI on March 9, 2022. Colors correspond to fractional reflectance values derived from a multi-band-multi-pass method for detecting methane absorption across bands 6 and 7.

NDTI-processed imagery from Landsat 8 OLI data. This image from October 2021 depicts the turbidity of Keweenaw Bay, western Michigan coastline of Lake Superior. Light blue-colored water indicates greater turbidity while darker blue water is less turbid. Turbid waters indicate coastal erosion and re-distribution of legacy copper mining waste colloquially referred to as "stamp sands". Stamp sands contaminate wetlands and threaten traditional food sources for Indigenous communities along the bay.

NDBI-processed imagery from a June 2022 Landsat 9 OLI-2 image. This composite image shows the cities of Warren (top left) and Youngstown (bottom right). The areas in white and brown represent the built environment. While areas in green represent land that is not as built-up, such as forest. Built-up areas can indicate where surface run off could occur, resulting in pluvial flooding.

Aph(433)-processed imagery from merged Aqua MODIS and Sentinel-3 data. This image of the Gulf of Maine was taken on September 12, 2016 during one of the most severe harmful algal bloom events. Using in-situ data, it was determined that Pseudo-nitzschia was a dominant genus of algae present at the time of the bloom. Shades of bright green indicate peak absorption by phytoplankton and aph(433) is corrected for false positive absorption indications.

Stormwater retention across Wyandotte County, Kansas. NASA GPM IMERG data for September 2020 – August 2021 and NLCD 2019 Land Cover data were used as model inputs for the InVEST Stormwater Retention Model. One model output included a stormwater retention ratio layer where darker purple values indicate poor stormwater retention and increased flood risk. Areas of poor stormwater retention can then be identified as priority regions for Green Infrastructure initiatives in Wyandotte County.

Forest/non-forest classification from 2022 Landsat 9 OLI-2 -derived imagery provided by NASA SERVIR. This image is of Volcan Baru in Panama. Green represents forest and blue represents agriculture and bare land. Yellow represents shrub, urban, wetland, plateaus, savanna, pastures, and pine. This forest/non-forest classification covers the entirety of the Mesoamerican Biological Corridor which provides valuable regional information to our partners.

Urban extent derived from Landsat 8 OLI data. This image shows urban extent in Guatemala City in 2020 as calculated using the Landtrendr algorithm in Google Earth Engine. The lighter colors of yellow and orange depict urban area, and the darker shades of pink and purple indicate the natural environment. Guatemala City has experienced rapid growth in recent decades, and local decision makers are interested in its impacts on various social and environmental factors.
