updated daily

HMS's smoke analysis is based on visual classification of plumes using GOES-16 and GOES-17 ABI true-color imagery available during the sunlit part of the orbit. Since the analysis generally requires a sequential set of satellite images to help distinguish smoke from clouds and other atmospheric aerosols, the first smoke analysis for the current day is usually produced around the local noon time – until then, only fire detection points may be available. Additional smoke analysis will occur throughout the day until sunset or as observation conditions permit.

The density information is qualitatively described using light, medium, and heavy labels that are assigned based on the apparent thickness (opacity) of the smoke in the satellite imagery.
