Data Usage Notes
06Jun2016
Newer NCEP Charts, those after 2004, are generally GIF and JPEG image formats, while older charts are in a less widely used 8-bit graphics and DFAX (radio fax charts) formats.
SRRS BIN archive units contain multiple binary clustered file units that consist of a concatenation of various binary formats, the vast majority being GRIBv1, GRIBv2, and BUFR.
The Pictorial (PCX) archive units contain several file units that are concatenated clusters of graphical formats. Unidata's GEMPAK is required to use some of them. Identifying many of these products can be difficult and there is no official documentation. Photoshop and other such programs may or may not be able to identify them.
