![Median daily evapotranspiration (ET) from September 2021 to May 2022 calculated from ISS ECOSTRESS data. The image covers the agricultural fields adjacent to the Maipo River, Chile and depicts water stress. The color scale ranges from red (low ET) to blue (high ET), with higher ET observed over irrigated agricultural fields. ET is used for estimating crop irrigation requirements. This data will inform irrigation management practices and help alleviate water scarcity within the area. ](/sites/default/files/styles/lis/public/2023-01/2022Sum_ID_IdahoWildfires_WebsiteImage.jpg.webp?itok=MgV2NTHF)

![Normalized difference vegetation index (NDVI) generated from an October 5, 2021 Landsat 8 OLI image of Yellowstone National Park. The dark green shades represent areas with healthy vegetation, yellow depicts bare ground, and intermediate shades reflect a gradient of vegetation productivity. Areas with NDVI values that vary throughout the year are indicative of deciduous vegetation and can help resource managers understand changes in aspen stand extent.](/sites/default/files/styles/lis/public/2023-02/2022Fall_GA_YellowstoneEcoII_WebsiteImage.jpg.webp?itok=9zItKz9L)

![NDTI-processed river imagery from 2021 PlanetScope data with GPM IMERG data shown in blue. The Shoshone River in northwestern Wyoming is shown with red values indicating lower turbidity and yellow values representing higher turbidity. Lighter blue values indicate higher monthly mean IMERG precipitation values for 2021. NDTI values and precipitation averages help watershed managers understand where and when excess sediment enters the river.](/sites/default/files/styles/lis/public/2023-02/2022Fall_PUP_ShoshoneRiverWater_WebsiteImage.jpg.webp?itok=myaPr9UA)

![Land cover imagery processed from Landsat 8 OLI and ocean turbidity data imagery processed from Sentinel-2 MSI. The Tijuana River stormwater plume off the San Diego coast was mapped from data collected on December 5th, 2019, while the land surface data was collected on April 4th, 2022. Shades of red indicate high turbidity values, while blue areas show normal turbidity values. Areas of high turbidity reflect high concentration of pollutants from stormwater runoff.](/sites/default/files/styles/lis/public/2023-02/2022Fall_ARC_SanDiegoWaterResources_WebsiteImage.jpg.webp?itok=Z3fy2AmA)

![NDVI imagery derived from Landsat 8 OLI data. This imagery showing the California’s Carmel and Salinas Valleys within the surrounding Santa Lucia Mountain range was collected in the Spring of 2019 . Light green areas show the more developed, agriculturally intensive areas of the valley while the dark blue areas show the less developed hills. NDVI calculations were used in models of forest cover changes in the area over time.](/sites/default/files/styles/lis/public/2023-02/2022Fall_CO_CarmelValleyEcoForecasting_WebsiteImage.jpg.webp?itok=AwlUPU2s)

![Annual max biomass calculated from 2021 daily Harmonized LandSat Sentinel-2 (HLS) dataset. Dark purple colors show low biomass while the bright orange show high biomass. Regions with high vegetation and tree canopy cover are shown in orange on the left of the image. High biomass values are of an interest to rangeland managers to help inform their grazing decisions based on which areas of the ranch produce the most biomass/vegetation.](/sites/default/files/styles/lis/public/2023-02/2022Fall_CO_EasternPlainsAgr_WebsiteImage.jpg.webp?itok=StO3rYYa)
