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.

The table below lists orbits that have some fixed scene view (scanner off or stare mode) data that interrupt the usual continuous daytime Earth scan data. Each affected orbit has an approximate 3 minute data gap. No further use of stare mode for Earth Probe TOMS is anticipated.
