Service Description:

Mean warm-season land surface temperature in degrees Fahrenheit for the CAPA Heat Study area of study. Averages derived from three Landsat 8 thermal band satellite images taken 04/26/2019, 06/13/2019, and 08/16/2019. Although more image were acquired, a decision was made to exclude images with cloud cover greater than 10% of the total image coverage. Cloud cover registered 0.02%, 2.71%, and 2.56% respectively for the three images used. Mean temperature across all non-cloud pixels was 84.57°F during this time period. Temperatures ranged from 70-102°F.

Disclaimer: A single image pixel depicts radiation from some area on the ground at 30 meters resolution. In reality, satellite instrument readings travel through an atmospheric column for retrieval increasing spatial variability in temperature, so the value retrieved from remote sensing is likely to be smaller than the hottest object in the pixel. Also although this dataset is called "land surface temperature," it does cover surface water.
