Dear Benjamin

we have already written such a routine.

You'll find it here
http://www.fz-juelich.de/icg/icg-i/idl_icglib/idl_source/idl _work/rb_lib
is_ncdf_file.pro

You need only to check the first three bytes of the file. If it is 'CDF'
then it is a netCDF file.

For further routines and licensing please have a look at

best regards
