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.

Chlorophyll-a imagery from Aqua MODIS for March 2022 in the Gulf of Maine. Simulated PACE OCI data are derived from Aqua MODIS. Areas in red have a high chlorophyll-a concentration, meaning that the water is high in nutrients such as nitrogen and phosphorus, which cause algae to grow. Areas in blue have a low chlorophyll-a concentration, so the conditions are not present for harmful algal blooms.

NDVI-processed imagery from Landsat 8 OLI/TIRS data. This composite image of Washington, D.C., and the surrounding area representing max green values over the summer months of 2022. Blue shades in the image represent vegetated areas, while green and yellow shades represent water and areas with no vegetation. Plant cover has a major impact on water quality, making it crucial for the National Park Service to understand the state of vegetation in this region.

NDMI-index imagery from Landsat 8 OLI and SRTM data, taken on August 30, 2022. The image showcases vegetation water content in the northern part of Capitol Reef National Park. Blue regions indicate vegetation with higher moisture content, vital in semi-arid environments. In contrast, red and yellow regions suggest less hydrated vegetation. This image offers valuable insights into moisture dynamics in arid regions like Capitol Reef.

Normalized Difference Vegetation Index (NDVI) of the Savannah River Estuary in Georgia calculated from an October 2022 image taken by NASA's Landsat 8 OLI sensor. Low NDVI values, including water, are represented in blue, while high NDVI values, showing areas of higher vegetation, are in green. Saltwater intrusion into coastal soils is impacting vegetation health in this area, causing tree die-off and the formation of ghost forests.

Lake Anna NDCI calculated using Sentinel-2 MSI images overlaying surface temperature imagery processed from Landsat 8 OLI data from May to September of 2021. Surface temperature is represented by shades of blue and green. Within the body of the lake, chlorophyll concentrations are represented on a gradient scale from purple to yellow, with yellow indicating highest concentrations. Higher temperatures can increase chlorophyll concentrations and are therefore of interest for Harmful Algal Blooms in Lake Anna.

Imagery from Landsat 4-5 TM, Landsat 7 ETM+, and Landsat 8-9 OLI from across the study period 2000-2021 over standard hill shade. Patches of blue show clear cut areas with lavender then yellow indicating higher magnitude. Green areas represent forests untouched during the study period.

Daytime average land surface temperature over June 2022 from ECOSTRESS, an instrument on the ISS. Warm colors highlight the City of Huntsville, which is surrounded by central North Alabama. In both color gradients, darker colors represent higher temperatures. The Tennessee River, together with Wheeler Lake (left) and Lake Guntersville (right), appear black. Surface temperature is one factor that can help the local government decide where to focus tree-planting efforts to mitigate urban heat.
