9.3.1.3 Seasonal/Annual Mean Radiation Budget Product

This file contains one season or one year of mean radiation budget data. It contains 25 records. The first record is the header. It contains six types of data: HIRS Night OLR, HIRS Day OLR, AVHRR Night OLR, AVHRR Day OLR, Available Solar Energy, and AVHRR SW Absorbed Radiation. Each type of data is associated with four records (the Northern Hemisphere pair and the Southern Hemisphere pair). The format of the header record has already been described in Table 9.3.1.2-1. The first data record of a hemisphere pair is described in Table 9.3.1.3-1, while data record 2 of a hemisphere pair is shown in Table 9.3.1.3-2.

Field Bytes Type Description
SPARE 1-2 I*2 SPARE
BCDDAY 3-4 I*2 The actual day number, relative to the satellite Epoch, of the first day in the period covered in file l (i.e. for monthly means the day is the relative to the first day of the month).
SPARES 5-12 I*2 SPARES
RCTYPE1 13-14 I*2 The indicator for the first record of the hemisphere:
02 = Record 1 for the Northern Hemisphere;
04 = Record 1 for the Southern Hemisphere.
SPARE 15-16 I*2 SPARE
FIELD 17-18 I*2 The Field mnemonic. (See Table 9.3.1.1-4).
NORS 19-20 I*2 The hemisphere indicator:
0= North;
1= South.
BEGINDATE 21-24 2 I*2 The start time as YYYYMM of the data in the record.
SPARE 25-26 I*2 SPARE
ENDDATEF 27-30 2 I*2 The end time as YYYYMM of the data in the record.
SPARES 31-276 I*2 SPARES
I2MAP 277-23,476 I*2 The mean values of the first 11,600 I*2 elements of the 20,626 elements of the Equal Areas/Equal Aspect Map

Table 9.3.1.3-2. Format of Seasonal/Annual Mean Data Record 2 of a Hemisphere Pair.
Field Bytes Type Description
RECTYP2 1-2 I*2 The indicator for the second record of the hemisphere:
03=Record 2 for the Northern Hemisphere;
05=Record 2 for the Southern Hemisphere.
FIELD 3-4 I*2 The Field mnemonic. (See Table 9.3.1.1-4).
NORS 5-6 I*2 The hemisphere indicator:
0= North;
1= South.
NCELL 7-186 90 I*2 The number of longitude bins in each of 90 latitude bands of the (current) Equal Areas/Equal Aspect Pathfinder Maps starting at the pole and abutting (to the west) the Greenwich Meridian.
SPARES 187-276 I*2 SPARES
I2MAP 277- 18,328 I*2 The mean values of the last 9026 I*2 elements of the 20626 elements of the Equal Areas/Equal Aspect Map
SPARES 18,329-22,036 I*2 SPARES
E2MAP 22,037-23,476 I*2 The 720 I*2 mean elements of the equatorial band data for the hemisphere
