Daytime average land surface temperature over June 2022 from ECOSTRESS, an instrument on the ISS. Warm colors highlight the City of Huntsville, which is surrounded by central North Alabama. In both color gradients, darker colors represent higher temperatures. The Tennessee River, together with Wheeler Lake (left) and Lake Guntersville (right), appear black. Surface temperature is one factor that can help the local government decide where to focus tree-planting efforts to mitigate urban heat.

Average aerosol optical depth (AOD) for the months of May and June in 2015 in Oregon and Washington, derived from MODIS data. Orange represents higher aerosol concentrations whereas purple represents areas with lower aerosol concentrations. The AOD averages show higher observed AOD along the coasts of Oregon and Washington.

Impervious surface imagery derived from Landsat 9 OLI-2 data. This composite was captured over the Finger Lakes region between April and October of 2022. Blue hues indicate dense vegetation while yellow hues indicate impervious areas. Areas in green indicate agricultural fields of interest to NGOs in the region that aim to prevent the conversion of agricultural lands to urban development.

Processed bands displaying NDVI from 30m Landsat 8 OLI data. The average 2022-2023 growing-season NDVI displayed is representing a heavy agriculture region within the Aconcagua River Basin in Central Chile. Blue to green colors represent areas of bare ground or water while yellow to dark red colors display densely vegetated regions. NDVI when compared to hydrology parameters can indicate heavily irrigated farmlands.

The data come from Landsat 9 OLI and MODIS satellites. The data shows surface reflectance imagery and combined (Terra and Aqua) MODIS burned areas from wildland fires in February 2023. The image shows parts of South-Central Chile covering Región del Maule, Región del Bío-Bío, and Región de La Araucanía. The processed data show burned areas in the region of interest from wildland fires and the smog from the fires. Red patches indicate burned areas.

Normalized difference vegetation index (NDVI) calculated from Landsat 8 OLI showing land and aquatic vegetation around the Kankakee River in northeast Illinois on June 9, 2022. For land, dark blue represents high vegetation while light blue represents low vegetation. For water, light orange represents lack of aquatic vegetation, while purple represents the presence of aquatic vegetation. The image shows where along the Kankakee River aquatic vegetation exists.

NDVI-processed image from Landsat 8 OLI June 2022 data. Black and magenta indicates Portland's built landscape, with the bright magenta depicting the highest concentrations of impervious surfaces. In light pink, the Willamette River dissects the city with surrounding green vegetation. The NDVI conveys areas with high urban build-up with a lack of access to greenspace, illustrating lived experiences of urban heat and contributing to Depave's knowledge of areas that are in most need of depaving.
