Table 7.

The names of the observation types available in the obs_seq_final files can be constructed by combining an entry from the first column (e.g. AIRS_) with an entry from the top row (e.g. TEMPERATURE), e.g. AIRS_TEMPERATURE. That type is the name for retrievals of temperature from the AIRS instrument on the AQUA satellite. QTY is an abbreviation for DART’s “quantity”, which denotes what is being measured, while TYPE denotes the source of the measurement. Each type was either assimilated , evaluated , (blank) ignored, or ‘X’ doesn’t exist.
