<rst> Format of the GRIB files retrieved for FLEXPART

===================================

The information given here is going to be part of easy matlab reading routines for the FLEXPART GRIB files.

A complete description of the `GRIB codes in table 128 <http://www.ecmwf.int:80/services/archive/d/parameters/order=grib_parameter/table=128/>`_ (ECMWF standard table) is available on the ECMWF pages (login required)

Here are the Grib records and variable names, units and descriptions in use in the FLEXPART GRIB files.

The last 8 records are all zero, and no longer existent in fields retrieved after 23 July 2007.
