How does GTSPP data get into ERDDAP

• On about the 5th of each month, ERDDP • replaces any of the files where any of the data has changed in the previous month and

• adds the three new tgz files for the previous month, so that his collection is up-to-date.

• For any month where one of the three files tgz has changed, ERDDAP

• uncompresses that month's three tgz files, • repackages the GTSPP netCDF files into just two big netCDF files, then

• adds the two big netCDF files to the collection of similar files for all of the months
