This document describes the file format of ancillary data files required for the MSBIN, MTBIN, MSPC, and MMAP routines of the MODIS ocean processing code. The contents of this document were taken from fileformat.Doc.6.V2.hqx.pff.doc which is included in the delivery of the MODIS ocean processing code to the GDAAC.
The files described below include :
For details of the file format of ancillary data files required for the MODCOL and MODSST routines, please refer to the documents : Input File Format Description - MODCOL and Input File Format Description - MODSST.
