![Normalized Difference Snow Index (NDSI) Image calculated from a May 2021 Landsat 8 top-of-atmosphere (TOA) reflectance image. The purple area depicts areas without snow and the yellow area represents areas with snow cover. This information can be used by refuge managers to monitor snow conditions and prepare for the ecological, cultural, and landscape impacts caused by snow.](/sites/default/files/styles/lis/public/2023-05/2023Spring_NCEI_NortheastAlaskaClimate_Websiteimage.jpg.webp?itok=vgp5Y_zU)

![The InVEST urban flood model produces various outputs, like the runoff retention seen here. The model output was derived from GPM IMERG, land cover, soil type, and curve number data. This image is from the extreme rainfall storm event on August 22, 2017. This image shows where the runoff is being retained in Kansas City, KA. The dark purple represents extremely high runoff retention while the yellow represents low retention with the green and blue representing increasing amounts of retention.

![Normalized Difference Snow Index (NDSI) processed image using Landsat 8 OLI data from January 2022 and SUOMI-NPP VIIRS snow cover data from January 2019, overlaid on a Landsat 8 RGB image, colorized purple. NSDI is shown in yellow-orange-red and SUOMI-NPP VIIRS is depicted in shades of blue. Snow cover data was used to identify melt events causing high turbidity in Wyoming’s Shoshone River basin. PlanetScope-derived turbidity (May 2019) also highlights the river in green.](/sites/default/files/styles/lis/public/2023-05/2023Spring_PUP_ShoshoneWaterII_WebsiteImage.jpg.webp?itok=YMzk_JP6)

This image depicts Pinyon-Juniper Woodlands (PJW), among other vegetation, between the river and mountains in a light green color. Thermal Infrared (TIR) occupies the red band, while the green and blue bands represent the Modified Normalized Difference Water Index (MNDWI) and the Modified Soil-Adjusted Vegetation Index (MSAVI), respectively.
