Hiya,

I'm pleased to announce the release of Decoders 3.0.2.

The major feature of the release is that the data is stored monotonically in
the netCDF model files. To accomplish this, the cdl valtime variable is
initialized with the valid times so the gribtonc program knows where to enter
the data into the netCDF file.  If one gets messages in the log file similar
to: "...  new valoffset = 12.000000" the data has extra offsets that should be
added to the cdl. In the cdl, the dimension valtime_offset should be
incremented by one and the new value entered in the data section of the cdl.
Included in the release is a new set of cdl files that have the valtime
variables already initialized to the proper values.

The cdl file names have changed to reflect the new model names, ie avn -> gfs
and they also include the grid number of the model. Here's the conversion:

                        avn-q   ->   gfs_211
                        avn-x   ->   gfs_37-44
                        ecmwf   ->   ecmwf_1-12
                        eta     ->   eta_211
                        mrf-a   ->   gfs_21-24
                        mrf-e   ->   gfs_25-26
                        ngm-q   ->   ngm_211
                        ocean   ->   ocean_21-24
                        ruc     ->   ruc_211
                        ruc2    ->   ruc2_236
                        sst-a   ->   sst_21-24
                        sst-t   ->   sst_61-64


Another variable forecasttime was added similar to the datetime variable in
previous cdl files. Using units: YYYY-MM-DD hh:mm:ssZ

To easy the transition to new pqact entries, the release includes a file
gribtonc.entries with all the needed entries and it's located in the cdl
directory or the etc directory.

Because of larger GRID products, the maximum GRID size was increase from 100k to
200k.

The metar2nc decoder was modified to make regular expression matching more
robust.

As always, if there are any question send them to support@xxxxxxxxxxxxxxxx

Thanks,
Robb...
