6.1 Ingest

Special purpose hardware/software is used to receive (ingest) data into the CEMSCS. This software includes polar satellite data, geostationary (GOES) satellite data, and Shared Processing data as received from, or transmitted between, the NESDIS and either the Air Force Global Weather Central (AFGWC) or the Navy's Fleet Numerical Meteorology and Oceanography Center (FNMOC).

Basically, the ingestor accomplishes the function of transforming the satellite Level 0 to a more processing friendly Level 1a data set as follows:

1. Accepts and synchronizes frames of Level 0 satellite data
2. First level quality control of data stream, filling data gaps as necessary. Generation and forward of a data quality/status file.
3. Extracting AVHRR and AIP data from Level 0 data and formatting to a Level 1a. These two data sets are made available for the process of Level 1b transformation.
4. Generation of a unique data set name which includes an orbit number and time duration of the pass
