Massachusetts Land Surface Temperature (LST) Index (2021)

MAPC Data Services produced a spatial land surface temperature (LST) index dataset for Massachusetts using satellite imagery captured in the months of April through October between 2018 and 2020. The LST index does not provide an actual surface temperature at each location throughout each region on a specific day. Rather, the LST index provides a relative measure, ranging from 0 to 1, representing each area’s tendency to be hotter than others in the region. The raster has a 30 meter spatial resolution. For each RPA region of Massachusetts, this download includes three complementary datasets: (A) the LST index for each 30-meter pixel, demonstrating spatial patterns of land surface temperature; (B) a 30m raster which depicts the variability in single-day normalized LST at each location; and (C) a vector-format polygon shapefile mapping the areas which have the 5% highest LST index values across the RPA region.
