Indonesian fires

Heavy smoke from Indonesia Fires.  The Suomi NPP  satellite using the  VIIRS instrument shows RGB+hotpost on left, OMPS AI overlaid on right. High AI values mean thick smoke, particularly since it’s probably low altitude (where AI lacks sensitivity). Because of this, some smoke clearly seen in VIIRS not seen by OMPS.
