Metis puts every free geostationary satellite — GOES, Himawari, GK2A, Meteosat, plus Sentinel, on one map, every layer traced to a named source (NOAA, USGS, EUMETSAT, Copernicus, Open-Meteo). Also a full hazard & water observatory: earthquakes, volcanoes, cyclones, USGS gauges, air quality, space weather. No signup, free, open source. Companion to Living Planet (earth.metiscore.space) — my offline NetCDF/GRIB2 tool for gridded climate data.
