Median day time Land Surface Temperature (LST) calculated using June – September 2016 – 2021 thermal imagery from Landsat 8 TIRS. Displayed is the city of Yonkers, located in Westchester County, directly north of the Bronx in New York City and right of the Hudson River. Shades of yellow–red indicate high LST. Green–teal shades indicate cooler LST. Solid purple represents water bodies. Focusing on yellow-red areas allows the city of Yonkers to prioritize heat mitigation strategies.

This image depicts chlorophyll-a concentrations along the Southern California Coast during a Harmful Algae Bloom, also known as a Red Tide Event. The ocean imagery was taken in April of 2020 by Aqua MODIS and used to generate chlorophyll-a concentration. The land imagery was taken by Sentinel-2 MSI during the same time period, and a Normalized Difference Chlorophyll Index was applied to it for visualization purposes. Blue and green indicates high and low chlorophyll-a concentrations, respectively. On land,

Normalized Difference Moisture Index (NDMI) processed 2021 Landsat 8 OLI imagery over land and Sentinel-2 MSI over ocean, ranging from yellow (low) to blue (high), for Hilo, Hawaii. Overlayed with four-day rainfall accumulation cells in blue acquired during Hurricane Lane (Aug 22-25, 2018) from CHIRPS Daily. NDMI monitors water content of leaves and is useful for classifying land cover. Impervious surfaces and areas that have received excessive historical rainfall are susceptible to future flood events.

In September 2020, the Mullen fire burned 176,000 Acres in Medicine-bow National Forest, WY. Sentinel-2 true color imagery with a difference normalized burn ratio from June 2021 shows different levels of burn severity (left). Black indicates areas of high severity, while grey represents lower severity. A NASA SRTM digital elevation model and cartographic elevation map overlays a post-fire cheatgrass detection layer (right).

Satellite image showing Venus flytrap habitat in coastal North Carolina. NDVI, derived from Landsat 8 OLI/TIRS sensors from April – July 2021, measures health and density of vegetation. Orange and red represent low and high burn severity, respectively, whereas pink and green represent low and high NDVI. The DEVELOP team used NDVI and fire severity data as input for Venus flytrap habitat suitability models, which botanists can use to support the conservation of Venus flytrap.

Temperature anomalies for 2020 were derived from Terra MODIS Daily Land Surface Temperature (LST) data and compared to the 20-year average (2000 – 2020) in Maine. Shown is an enlarged subset of Maine. Stream vectors are represented in light blue. Blue pixels represent decreases in LST (cooler temperatures), green pixels represent areas of neutral change (average temperatures), while red and yellow pixels represent increases in LST (the highest temperatures).

High transition potential is depicted in yellow and low transition potential is indigo. Transition potentials help to forecast land cover and inform land managers on the locations of suitable bighorn sheep habitat.
