However, there are examples of programs to write or read netCDF data, in various languages, here: http://www.unidata.ucar.edu/netcdf/examples/programs/index.html You could start by looking at the way the data is stored, using the ncdump command-line utility program with something like $ ncdump -h avhrr-only-v2.20130115.nc which shows you information about the sst variable: short sst(time, zlev, lat, lon) ; sst:long_name = "Daily sea surface temperature" ; sst:units = "degrees C" ; sst:_FillValue = -999s ; sst:add_offset = 0.f ; sst:scale_factor = 0.01f ; sst:valid_min = -300s ; sst:valid_max = 4500s ; Then you could adapt one of the example programs listed on the web page above, such as: C: pres_temp_4D_rd.c Fortran 77: pres_temp_4D_rd.f Fortran 90: pres_temp_4D_rd.f90 C++: pres_temp_4D_rd.cpp Java: Pres_temp_4D_rd.java Contributed: Python: pres_temp_4D_rd.py MATLAB: pres_temp_4D_rd.m Perl: pres_temp_4D_rd.pl IDL: pres_temp_4D_rd.pro which all read values from similar 4-dimensional variables.
