NOAA HMS Smoke Detection

NOAA Satellite Analysis Branch's daily analysis of smoke locations across North America.

This layer shows the areas with observed smoke associated with fires using the latest satellite imagery from the NOAA Hazard Mapping System (HMS). The smoke analysis is based on visual classification of plumes using GOES-18 and GOES-19 Advanced Baseline Imager (ABI) true-color imagery available during the sunlit part of the day. A new daily map is initiated around 7-8AM  Eastern Time although since the analysis generally requires multiple 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 and updates will occur throughout the day until sunset or as observation conditions permit.
 

  Smoke attributes carry the start and end times (in Universal Time Coordinated - UTC) of the satellite image sequence used to outline the smoke polygon, the corresponding satellite from which the image was derived, and the plume density. The density information is qualitatively labeled as light, medium, and heavy based on the apparent thickness (opacity) of the smoke in the satellite imagery. Those three distinct groups are meant to approximate smoke concentrations ranging between 0-10, 10-21, and 21-32 micrograms per cubic meter, respectively, although no guarantee is made about the actual smoke density measured in the atmospheric column surrounding those areas.    Email your questions to the HMS fire team at: [email protected]
