This image of the San Francisco Bay region illustrates the thermal (heat) radiations differences in urban materials. The reds show more heat emissions and the greens show less heat emissions. The water of the San Francisco Bay and Pacific Ocean (lower left) appear black.
This image was acquired by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA's Terra satellite.
