Global Surface Reflectance and Sea Surface Temperature

MODIS provides frequent (every 1-2 days) global views of many of the Earth’s vital signs. This image shows a false-color land surface, derived using MODIS’ Surface Reflectance Product, and a false-color sea surface temperature map (red and yellow are warmer, blues are cooler).
