9. Record Description of the IASI Level 1 Products |
In the tables below, coloured items have the following meanings:
Compound data type, which consists of at least two basic or other compound data types. The name of the compound data type is shown first, followed by a list of the items contained within it. Dimension parameter for variable product fields.
The following three main sections provide descriptions for IASI Level 1a, Level 1b and Level 1c respectively.
PFV = 10.0 PFV = 11.0 Record name Record version Record version mphr 2 2 giadr-quality 2 2 giadr-scalefactors 2 2 mdr-1a 4 5 (new version)
If more than one version of a record exists, all versions are described below.
Certain record types with formats common to all products (IPR, DMDR, GEADR, VEADR) are not included below, since they are not relevant to the average user. If required, details of these records can be found in the Generic PFS [RD11]
