This is a visualization of ECOSTRESS’ Evaporative Stress Index in Marin County, CA. The data is an average of summer months from 2018 – 2022. Scores closer to 0, or red/orange areas, indicate plants are in stress, meaning they are not meeting their potential evapotranspiration, while scores closer to 1, or blue areas, indicate plants are thriving and closer to reaching potential evapotranspiration.

ACOLITE and NDVI processed imagery from Landsat 9 OLI-2 data. This composite image of the Coos Estuary and surrounding area was taken in September of 2022 after a period of increased precipitation. Shades of blue indicate vegetated land surface. The darker purple indicates higher turbidity while the lighter orange indicates lower turbidity.

Tasseled Cap Wetness calculated from Landsat 9 OLI-2 imagery from October 25, 2022. The Paria River, shown in dark blue, passes through the landscape. Shades of lighter blue indicate higher values of Tasseled Cap Wetness, with the gradient going towards dark purple and then bright pink for the lowest values of Tasseled Cap. Areas with higher Tasseled Cap Wetness values indicate moister environments, which can enable invasive species proliferation in riparian ecosystems.

Predicted cheatgrass green-up imagery from Landsat 8 OLI data. This composite image of the western portion of the Mullen Fire Study Area is from June 2022. Shades of green and yellow indicate an earlier green-up time, while orange, brown, and white areas show later predicted green-up times. This data was used to create NDVI difference maps which will help managers predict when and where to apply treatments to limit the spread of cheatgrass.

A 3D rendering of Landsat 8 OLI data processed using a Normalized Difference Moisture Index (NDMI). This image of the southeast region of Bandelier National Monument was taken on September 10, 2022. The Rio Grande is shown on the right side in dark purple, with upland areas shown in light green. NDMI highlights the areas of high moisture content, around which vegetation is more prevalent, as seen in indigo.

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.

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.
