The format used for the delivery of the data is netCDF. This is a binary format for which there is a substantial amount of software available. Because of all of the information contained in the netCDF file structure, every station is contained in a separate netCDF file.
A sample of the output of the "ncdump" utility on a file is shown here. Explanations of the contents of the various fields are present in this file.
