A simplified high and near-constant contrast approach for the display of VIIRS day/night band imagery

Abstract

The European Organisation for the Exploitation of Meteorological Satellites has developed a simplified high and near-constant contrast approach for the display of Day and Night Band (DNB) data of Suomi National Polar-orbiting Partnership (S-NPP) satellite's instrument Visible Infrared Imager Radiometer Suite (VIIRS). Simple applications like service monitoring or operational weather forecasting (nowcasting) can thus take direct advantage of the VIIRS DNB Level 1 data without the need for using Level 2 processing, Level 2 data or using ancillary data like look-up tables. This method is based on a fixed 'correction curve' and simple formulas, and can thus be applied sequentially to single granules as, e.g., received through direct broadcast dissemination systems. Especially the European Nordic Countries need to rely on good contrast imagery for operational weather forecasting during the extended twilight periods from autumn to spring. ARTICLE HISTORY

Ocean Dynamics Observed by VIIRS Day/Night Band Satellite Observations

“…There are other approaches, such as Near Constant Contrast (NCC) [38,39], to produce contrast imagery for comparing daytime and nighttime observations. However, the method used in this study has several advantages for the DNB observations over the ocean.…”
