Level 1A Data (Not recommended for most users!)(Not recommended for most users!)

= Raw, un-calibrated swath data= Does include lat, long reference

Level 2 Data = More calibration, swath data= Does include lat, long reference

Level 2G Data (minimal processing level for “MOST” users)

= Calibrated = Integerized Sinusoidal Projection, tiled

Level 0 Data (Not recommended for most users!)(Not recommended for most users!)

= Unprocessed instrument/payload data at full resolution

Level 1B Data (need special software to process)

= Processed swath data to sensor units (i.e. calibrated radiance)= Does include lat, long reference
