Satellite Fire Detection and Smoke Capabilities for Alaska Users

The purpose of this document is to assist in the operational use of new satellite capabilities for IMETs and Predictive Service Meteorologists in Alaska. Sources for both AWIPS and non-AWIPS users are provided. Because of Alaska’s northern latitude, polar satellites pass frequently over the region, and with Direct Broadcast reception, data is typically available within 30 minutes of the end of the satellite overpass. Your feedback is greatly appreciated. (Contact: jorel.torres@noaa.gov)

Fire Point Mapping in Alaska:

This video shows a time lapse of the fire heat points detected by GINA over the course of the 2024 Alaska Fire Season from April 9, 2024 to August 19, 2024. Recent fire points are displayed as bright red and fade to brown after a few days. Fire points frequently appearing in the same location indicate an actively burning wildfire. This product doesn’t detect points that are under cloud cover or thick smoke. This product is used by the Alaska Fire Service for detecting active fires on the Alaska Wildland Fire Information Map. For more videos from the 2024 season, check out our blog post on the 2024 fire season.
