Fire risks are quite high these days in Southern California. And some fires have even already been observed by the Sentinel-3 (S3) B satellite, from the European Copernicus programme. Here below are some Red-Green-Blue (RGB) pictures from the Level 1 (L1) measurements of the optical S3B sensors, disseminated by EUMETSAT: the Ocean and Land Colour Instrument (OLCI) and the oblique view of the Sea & Land Surface Temperature Radiometer (SLSTR). These images show smoke aerosol particles spreading from North of Los Angeles over Pacific.
As illustrated by @weatherchannel, these areas are located in “Critical” fire danger zones.
