Alaska - VIIRS Active Fire Detections

Near-real-time active fire and thermal anomaly detections from NASA's [Fire Information for Resource Management System (FIRMS)](https://firms.modaps.eosdis.nasa.gov/active_fire/) covering **Alaska**, derived from the **VIIRS** sensor family (Suomi-NPP since 2011, NOAA-20 since 2017, NOAA-21 since 2022). Each resource is an external link directly to a NASA-hosted file. The files are continuously updated as new satellite overpasses are processed (typically within 3 hours of acquisition). **Formats:** SHP, KML, CSV **Time windows:** Last 24h, 48h, 7d Files (slice {"file": url}): - VIIRS S-NPP C2 (Suomi-NPP) - 24h (CSV) (csv): https://firms.modaps.eosdis.nasa.gov/data/active_fire/suomi-npp-viirs-c2/csv/SUOMI_VIIRS_C2_Alaska_24h.csv - VIIRS S-NPP C2 (Suomi-NPP) - 48h (CSV) (csv): https://firms.modaps.eosdis.nasa.gov/data/active_fire/suomi-npp-viirs-c2/csv/SUOMI_VIIRS_C2_Alaska_48h.csv - VIIRS S-NPP C2 (Suomi-NPP) - 7d (CSV) (csv): https://firms.modaps.eosdis.nasa.gov/data/active_fire/suomi-npp-viirs-c2/csv/SUOMI_VIIRS_C2_Alaska_7d.csv - VIIRS NOAA-20 C2 - 24h (CSV) (csv): https://firms.modaps.eosdis.nasa.gov/data/active_fire/noaa-20-viirs-c2/csv/J1_VIIRS_C2_Alaska_24h.csv - VIIRS NOAA-20 C2 - 48h (CSV) (csv): https://firms.modaps.eosdis.nasa.gov/data/active_fire/noaa-20-viirs-c2/csv/J1_VIIRS_C2_Alaska_48h.csv - VIIRS NOAA-20 C2 - 7d (CSV) (csv): https://firms.modaps.eosdis.nasa.gov/data/active_fire/noaa-20-viirs-c2/csv/J1_VIIRS_C2_Alaska_7d.csv - VIIRS NOAA-21 C2 - 24h (CSV) (csv): https://firms.modaps.eosdis.nasa.gov/data/active_fire/noaa-21-viirs-c2/csv/J2_VIIRS_C2_Alaska_24h.csv - VIIRS NOAA-21 C2 - 48h (CSV) (csv): https://firms.modaps.eosdis.nasa.gov/data/active_fire/noaa-21-viirs-c2/csv/J2_VIIRS_C2_Alaska_48h.csv - VIIRS NOAA-21 C2 - 7d (CSV) (csv): https://firms.modaps.eosdis.nasa.gov/data/active_fire/noaa-21-viirs-c2/csv/J2_VIIRS_C2_Alaska_7d.csv
