Abstract

The Operational System of Linear Scan (OLS) of the Defense Meteorology Satellite Program (DMSP) has a unique ability in discovering visible and near-infrared (VNIR) portion of the electromagnetic spectrum at night. With visible band data of OLS, it is possible to find clouds that are illuminated by the moonlight, as well as light of cities, towns, industrial spots, gas burners and temporary events such as fires and clouds that have become bright by lightning. This paper describes the methods that have been developed to discover and determine the location of VNIR release sources; of course, it is carried out to detect fixed spatial propagation centers by cities, towns and industrial areas using DMSP-OLS overnight data and analysis of multi-time image series.
