NDVI over Mato Grosso, Brazil processed from March 2021 Landsat-8 OLI data. Calculated NDVI values correspond with colors shown to indicate plant health. High NDVI values (green to blue) indicate dense vegetation found in tropical and temperate forests or crops at their peak growth. Low values (yellow to red) depict barren land, water, and moisture-stressed vegetation. These data can support timely and efficient agricultural responses to ensure productive yields and food security.​

This image of the Chesapeake Bay is derived from NASA Landsat 7 ETM+ and Landsat 8 OLI imagery. It represents median Normalized Difference Turbidity Index (NDTI) turbidity levels from January 2020 through June 2022. Yellow and orange areas indicate higher turbidity levels. This imagery can be used to determine areas of the bay in which turbidity poses a threat to water quality.

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. ​

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.​

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.​
