Soil organic carbon (SOC) is measured here for a depth of 0-5cm from Soil Moisture Active Passive from January 1, 2021 over Peru and Bolivia. SOC is visualized against combined MODIS landcover data for the year 2000 from Aqua and Terra. Shades of lighter pink indicate lower SOC content and darker shades of pink and purple indicate higher SOC content. Conservation International is interested in mapping areas of high SOC content for their conservation efforts.

The green areas show stable forest in NW Alabama classified by both National Land Cover Dataset (2016-2019) and Landscape Change Monitoring System(2016-2021), and the pink areas are areas where forest cover loss was sensed by NLCD, LCMS, LandTrendr (2016-2021), and Global Forest Watch (2016-2021). These datasets and the basemap were made with Landsat 5 Thematic Mapper, Landsat 7 Enhanced Thematic Mapper Plus, and Landsat 8 Operational Land Imager.

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.

Albedo derived from Landsat 8 & 9 OLI data throughout summer 2019 to 2023. White beige pixels signify effective solar radiation reflection (higher albedo), followed by peach, violet, and dark purple. This data is input for the InVEST Urban Cooling model, which calculates heat dissipation efficiency. Light-colored roofs and dense vegetation can increase albedo. Urban areas with lots of purple patches may be more vulnerable to heat, making them a priority for heat mitigation efforts.

NDVI map calculated from an April 2023, Landsat-8 OLI image of Coronado National Memorial and the surrounding area. The shades of green represent current vegetation, while areas in bright yellow and dark orange represent areas with little to no vegetation. By selecting an image during the dry season, the map highlights the unique ecosystem of sky islands which is characterized by changing vegetation at different elevations.
