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).
