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.

Normalized Difference Water Index (NDWI) to visualize drainage networks around the Unalakleet River in Alaska, calculated from an August 2021 Landsat 8 OLI image. Yellow represents standing or flowing water and potential flood zones, while the dark blue represents drier, upland regions. Unalakleet's climate resilience planning prioritizes relocation to upland regions while avoiding areas that have experienced significant permafrost degradation.

Runoff retention values in Richmond, VA estimated by the InVEST Urban Flood Risk Mitigation Model for a June 2, 2018, extreme rainfall event measured by GPM IMERG. Dark blue areas have high runoff retention capacity and absorbed more of the rainfall during the storm; light green areas absorbed less rainfall during the storm, increasing the likelihood of pluvial flooding. Pluvial flood risk maps help inform community planners’ efforts to protect vulnerable populations.
