NetCDF allows you to extract selected data in "hyperslabs".  Assuming your
data has been stored properly, you could extract data from a single station
by identifying the variable ID of the station, and then selecting the
data that corresponds to it.

The netCDF users guide describes the netCDF interface, the components
of a netCDF file, netCDF data types, the usage of the netCDF library,
netCDF operations, dimensions, variables, and attributes.  You should
be looking at the chapter on the usage of the netCDF library, which
describes the *sequence* of commands that your program should use, including
examples.  Then you should look at the descriptions of the netCDF
operations that you must use to open and inquire about the file, select
the data, extract it, and then close the file.  Again, all the discussions
about each netCDF library operation come with examples.

If the netCDF users guide does not answer all your questions, I suggest
that you use the netCDF FAQ (frequently asked questions), README, and
txt (text) files that are available with the software package.  You may
access these additional materials from the anonymous ftp at unidata.ucar.edu,
Mosaic server (http://www.unidata.ucar.edu/).
