Next Generation Fire System (NGFS) - Experimental ; CIMSS

August 2026: The UW campus has an ongoing chilled water disruption that will limit SSEC datacenter cooling and could lead to data outages with no warning. Please consider accessing NGFS detections and satellite imagery through the NOAA/NESDIS Wildland Fire Data Portal: https://fire.data.nesdis.noaa.gov/map/
