20000801: ETA gridded data & garp

Dana,

If these are ETA grids, then the file names should say eta instead of
mrf as you show below. 

So, presumably you would have file names like:
2000072600_eta_80km_211.gem   

The two lines in Garp_defaults that acontrol the model menu are
modelkeys and modellabels. The modelkeys are the strings used to uniquely
identify the model in the $HDS directory. The modellabels are the strings to 
present
in the pull down menu to relate to each modelkey.

By default, the pqact.conf entries I provide store the ETA 211 grids as
YYYYMMDDHH_eta211.gem, so the modelkey that uniquely identifies these
files in the data directory is eta211 (eg, eta211 is a string within the
file names in the data directory that can differentiate it from other
ETA files, such as the 212 40km grids in YYYYMMDDHH_eta212.gem).

To use the file name 2000072600_eta_80km_211.gem as shown above,
you might use the modelkey eta_80 instead of the eta211 as I suggest, eg:
modelkeys       : "eta_80, etc.....
modellabels     : "ETA 80km"

If you chose not to name the files as I do, then you will want to
change all the eta211 strings in the configuration file, eg:
eta211_proj
eta211_garea
and the widget defaults:

# Widget defaults
#
# Choose default values for the model, vertical coordinate, levels,
# function, default fdf chapters, cross-section line, time-height
# station, vertical profile axis types, radar ring station, upper
# air levels and upper air filter.
#
model           : eta211


The_proj and _garea above define the default map region to use for a given
modelkey. The model tag above is the default model that shows up when
you first pop up the model window.

Lastly, the $GARPHOME/fdf/scalar and vector directories provide directories
for the gfunc optionds for each modelkey. You would want to create a 
link from eta211 to eta_80 if you used you naming above.
