[ncl-talk] File not supported

[David Brown]

Hi Debasish,

This file does not appear to be a grib file. Both wgrib and wgrib2
fail to open it, so it is not just NCL that has a problem with it.

Here is wgrib and wgrib2  output:

$ wgrib ngac.t00z.aerf15
found unidentified data
$ wgrib2 ngac.t00z.aerf15
$                                             # no output at all

There appears to be some ascii data in the file that suggests
atmospheric data. The first few characters hint at some kind of binary
format:

0NEMSIO  GFS     bin4

You will need to find out from the source what sort of file this is
and what needs to be done to make sense of it.
