HICO ancillary data

Hi,
How can I access ancillary data used for HICO processing?
(wind speed and direction, atmospheric pressure, ozone and water vapour content)

best regards

Christophe

Christophe,

We have not fully integrated HICO processing support. The code *can* process HICO, but we've not had the time
to evaluate it or generate reasonable calibration adjustments.

We will eventually add support for HICO to the getanc.py script, until then you can call getanc.py with the
--start option (and optionally --stop, although HICO scenes are sufficiently small to not likely require it)

For example, given the file: H2013304171748.L1B_ISS
you would call getanc.py as:

getanc.py --start=2013304171748

Regards,
Sean

Dear Sean,

thank you very much for your reply.
How can I read the *_NCEP.MET files?

I tried with wgrib tools but it did not work out.

best regards

They are in HDF4 format.

For future reference, the file command can often identify the type of a file:


$ file S200616718_NCEP.MET
S200616718_NCEP.MET: Hierarchical Data Format (version 4) data

The hdfview program (part of hdf-java) can usually read netcdf and hdf files (both older and current versions of the formats).
