There is an IDL function, <a href="http://cars.uchicago.edu/software/idl/detector_routines.html#read_nd_netcdf">

This routine is contained in the <a href="http://cars.uchicago.edu/software/idl/detectors.html#read_nd_netcdf">
CARS IDL detector package</a>. This function is currently limited to reading the
entire file at once, so it may fail for very large files on machines with insufficient
