Repeat the following 11 octets for each contributing band (nb = 1,NB) (24+11(nb-1)) - (25+11(nb-1)) Satellite series of band nb (code table defined by originating/generating centre) (26+11(nb-1)) - (27+11(nb-1)) Satellite series of band nb (code table defined by originating/generating centre) (28+11(nb-1)) - (29+11(nb-1)) Instrument types of band nb (code table defined by originating/generating centre) (30 +11(nb-1)) Scale factor of central wave number of band nb (31+11(nb-1)) - (34+11(nb-1)) Scaled value of central wave number of band nb (units: m-1) |
| Note : (1) For "satellite series of band nb", "satellite numbers of band nb" and "instrument types of band nb", it is recommended to encode the values as per BUFR Code ables 0 02 020, 0 01 007 (Common Code Table C-5) and 0 02 019 (Common Code Table C-8), respectively. |
