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.

NDVI-processed imagery from Landsat 8 OLI data. This image of Baltimore and surrounding cities is a composite of Summer 2013 to 2023. Shades of purple indicate vegetated land surface, while darker orange shades show the built landscape; meanwhile, shades of yellow indicate water bodies. Areas of low NDVI are at-risk of high temperatures and is an indicator for Maryland’s transit system to focus on communities most vulnerable of urban heat island impacts.

Mean surface temperature of the Greater Bridgeport coast in Connecticut. Calculated from Landsat 8 TIRS and Landsat 9 TIRS-2 imagery from June to September for each year from 2013 to 2023. Dark red represents high land surface temperature and will inform the locations of cooling interventions for Groundwork Bridgeport’s Cool Corridors project. Yellow represents a more moderate land surface temperature, whereas dark and light blues represent high and moderate sea surface temperatures respectively.

S17 NDWI calculation within the Alaskan east Kobuk river generated from NASA Landsat 8 OLI imagery taken on March 9th, 2023. The NDWI values, displayed above in a purple palate – pink displaying ice and purple displaying flowing water – were used to determine the dates of freezing. The NDWI calculation is overlayed on Sentinel-2 MSI imagery from October 26, 2022.

MNDWI-processed imagery from Landsat 8 OLI. This composite image of Mud Lake Wildlife Management Area and Camas National Wildlife Refuge in Southeast Idaho was taken over April and May, 2018. Higher values, blue and dark green shades, indicate surface water. Lower values, red and orange shades, indicate bare ground or senesced vegetation. Yellow and light green indicate living vegetation, such as irrigated crops. Areas with high MNDWI values can help identify wetlands' surface water.

This NDVI maximum composite image of northwestern Alaska was created from a harmonized Landsat 8 OLI, Landsat 9 OLI-2, and Sentinel-2A/B cloudless image series from May to September 2023. The image has been processed to overlay a low to high: soft green-yellow-dark green-brown color scheme to display the varying vegetation in the region represented by different NDVI values. This image can assist in conservation decision-making by highlighting areas with high vegetation availability for caribou.
