| id | field name | definition |
|---|
| 0 | RECORD_CLASS |
| binary uint8 | size: 1 |
|---|
|
Class of this record (0 = Reserved, 1 = Main Product Header Record (MPHR), 2 = Secondary Product Header Record (SPHR), 3 = Internal Pointer Record (IPR), 4 = Global External Auxilliary Data Record (GEADR), 5 = Global Internal Auxilliary Data Record (GIADR), 6 = Variable External Auxilliary Data Record (VEADR), 7 = Variable Internal Auxilliary Data Record (VIADR), 8 = Measurement Data Record (MDR))

| 1 | INSTRUMENT_GROUP |
| binary uint8 | size: 1 |
|---|
|
Group defining the record subclasses (0 = GENERIC (no specific instrument), 1 = AMSU-A, 2 = ASCAT, 3 = ATOVS instruments (AVHRR/3, HIRS/4, AMSU-A, MHS), 4 = AVHRR/3, 5 = GOME, 6 = GRAS, 7 = HIRS/4, 8 = IASI (except IASI L2 products), 9 = MHS, 10 = SEM, 11 = ADCS, 12 = SBUV, 13 = DUMMY, 14 = ARCHIVE (Note: Only used in GIADRs. A GIADR with INSTRUMENT_GROUP of archive contains only descriptive information and is not processed), 15 = IASI_L2 (used for IASI L2 products only))
