NOAA KLM User's GuideSection 9.7.4 |
The data dictionary contains an entry for each lowest level data item, and in some cases, group items, found in each of the OOPS data sets. Where the same information occurs on more than one data set, even if stored in different units (e.g., radians vs. degrees), it has been given a common name and only occurs once in the data dictionary. Individual byte/bit breakdowns (e.g. series of 1 bit flags) of these items will not be listed as separate entries in the data dictionary.
The data set name abbreviations used in the data dictionary are given below for reference:
