摘要

The Visible Infrared Imaging Radiometer Suite (VIIRS) collects global day and night data uwing 22 spectral bands. The nighttime data are particularly useful for defining the temperature of hot objects (IR emitters). Using a full year of VIIRS data it is possible to divide IR emitters into two classes: ephemeral and persistent. Among the persistent set, sites can be divided into gas flares and industrial sites. The gas flares are 1400 K and higher. The industrial sites are under 1400 K. For the ephemeral IR emitters there are two primary classes: biomass burning and gas flares. Biomass burning typically dominates, in terms of numbers of detections. If a site is ephemeral and 1500 K or higher, it can be assigned as a gas flare. Ephemeral emitters with temperatures less than 1500 K. are biomass burning.
