8.3.1.4.2.2 NOAA-N Header Records (version 3, post-April 28, 2005, all spacecraft)

With the exception of the zero-fill padding, the format specifications for the GAC Level 1b primary header record for NOAA-N is the same as the LAC/HRPT header record (Table 8.3.1.3.2.2-1). Please note that as part of the updates to the Level 1b formats for NOAA-N and -N' is the inclusion of additional, or secondary, header records. They will contain ancillary data set names and any metadata needed for reprocessing. Currently, the content and format of any secondary header records is to be determined. Applications that will access Level 1b data sets should use the "Count of Header Records in this Data Set" field, located in the first, or primary, header record, to calculate the position of the first data record and skip the secondary header records.
