Nighttime satellite imagery from the Defense Meteorological Satellite Programs' Operational Linescan System (DMSP OLS) is being used for myriad applications including population mapping, characterizing economic activity, disaggregate estimation of CO2 emissions, wildfire monitoring, and more. Here we present a method for in situ radiance calibration of the DMSP OLS using a ground based light source as an active target. We found that the wattage of light used by our active target strongly

We recommend exploring the possibility of establishing a permanent active target for the calibration of nocturnal imaging systems. OPEN ACCESS Remote Sens. 2014, 6 12709
