EP/TOMS Missing Data
The tables below indicate data that are permanently missing from the Level-2 EP/TOMS data record. Some filling can occur in the Level-3 product due to overlapping data from adjacent orbits. Also, additional gaps may occur in the Level-3 data resulting from bad retrievals due to desert dust or smoke from forest fires as described in the EP/TOMS Data Products User's Guide.
