9.7.3 OOPS Standard Header

Each monthly and daily SBUV/2 product has a pair of standard header records at the beginning of the data set that describe the contents of that data set. The standard headers include information such as the range of data coverage and the version number of the data set (for those situations where the data is recreated , e.g., due to changes in instrument calibration).

The 1b data set also contains standard headers describing each input data set (e.g. meteorological) used to build the 1b. The Product Master File will have the 1b standard header records in addition to its own standard headers.Starting with Version 8 PMFs in 2007,the 1b datsets are the only externally distributed dataset that will contain the OOPS Standard Header Records

The format of the OOPS standard header is given on the following pages. Definitions of individual items can be found in the Data Dictionary, Section 9.7.4.
