GREETINGS!

The Earth Observation Group (EOG) specializes in nighttime observations of lights and combustion sources worldwide. The group started working with Defense Meteorological Satellite Program (DMSP) data in 1994 and has produced a time series of annual cloud-free composites of nighttime lights. EOG’s current focus is on deriving products from nighttime Visible Infrared Imaging Radiometer Suite (VIIRS) data.
