OMI Near Real Time data processing

The Ozone Monitoring Instrument (OMI) is a satellite instrument that measures ozone columns and profiles, aerosols, clouds, surface ultraviolet (UV) irradiance, and the trace gases. OMI was initially setup for processing standard products when the best data became available. The capability to produce Near Real Time (NRT) data was added later. In order to accomplish this it was necessary to modify algorithms and the processing system in order to reduce latency while still ensuring quality. This paper presents the challenges of producing a NRT System for the OMI instrument from the standard processing system.
