NDBI-processed imagery from a June 2022 Landsat 9 OLI-2 image. This composite image shows the cities of Warren (top left) and Youngstown (bottom right). The areas in white and brown represent the built environment. While areas in green represent land that is not as built-up, such as forest. Built-up areas can indicate where surface run off could occur, resulting in pluvial flooding.

Aph(433)-processed imagery from merged Aqua MODIS and Sentinel-3 data. This image of the Gulf of Maine was taken on September 12, 2016 during one of the most severe harmful algal bloom events. Using in-situ data, it was determined that Pseudo-nitzschia was a dominant genus of algae present at the time of the bloom. Shades of bright green indicate peak absorption by phytoplankton and aph(433) is corrected for false positive absorption indications.

Stormwater retention across Wyandotte County, Kansas. NASA GPM IMERG data for September 2020 – August 2021 and NLCD 2019 Land Cover data were used as model inputs for the InVEST Stormwater Retention Model. One model output included a stormwater retention ratio layer where darker purple values indicate poor stormwater retention and increased flood risk. Areas of poor stormwater retention can then be identified as priority regions for Green Infrastructure initiatives in Wyandotte County.

Normalized burn ratio calculated from Landsat 8 imagery both preceding and following the Bootleg Wildfire in the Beatty, Oregon area. The fire burned from July 6th to August 15th during the Summer of 2021 and its footprint shows varying levels of burn severity. Dark purple areas indicate highest severity, shades of red and orange indicate moderate severity, and yellow areas indicate low burn severity. Black areas depict unburned areas.

Landsat 8 OLI data processed into the median NDVI for 2016-2021 with an overlay showing deforestation that occurred during this time period in the Talladega National Forest. The deforestation layer is derived from Global Forest Watch's forest cover data, which uses the Landsat series, and was calculated as the difference between forested areas in 2016 and forested areas in 2021. Shades of green indicate the density of forest, while red areas indicate areas deforested in 2021.

This image of Land Surface Temperature (LST) illustrates the urban heat island (UHI) effect that Milwaukee County experiences. Light orange areas represent hotter temperatures, which are concentrated in the high impervious areas of the city. Darker pinks represent cooler rural areas and underscore the temperature contrast across the landscape. The hotter areas of the city are historically redlined communities of color that disproportionately feel the effects of the UHI, including higher energy bills heat re

Daytime land surface temperature for Wichita, Kansas summer 2017-2022, retrieved through Landsat 8 TIRS and Landsat 9 TIRS-2 surface temperature. Located in the northwest corner of the city, this image depicts higher temperatures through dark orange hues in developed areas, and lighter orange hues to blue colors where the temperature is lower. The land surface temperature was utilized to construct a heat vulnerability index for the city, looking into disproportionate impacts on underserved communities.

This image shows the mixed environments near the American Falls Reservoir throughout the year, blended using 2022 summer and winter NDVI false-color composites derived from Landsat 8 OLI and overlaid by a hillshade from SRTM. The white color indicates snowpack in the mountain wilderness, the primary water resource for agriculture and habitats near the reservoir. Bright red denotes marshes and irrigated farms, essential resources for wildlife animals and humans living in Southern Idaho.
