ETAMAP

This utility program has been provided to assist in the configuration of a computational domain for your WS Eta runs. It is strongly recommended that you use this program to establish the areal coverage of your model runs prior to running the model. The program is based on the GEMPAK program, GPMAP, but takes the the parameters used to define your model domain as defined in eta_run.csh. The default output is an X-window but you can also generate a gif or postscript file.

If you are using a current SOO/STRC NAWIPS distribution you already have etamap in the $GEMEXE directory. If you use the UNIDATA distribution you will need to install and build etamap

The program and attendant files should be installed with your NAWIPS 5.6 distribution.

To install:

As user gempak

% mv etamap56.tar.gz $NAWIPS - (usually /usr1/nawips)
% cd $NAWIPS
% zcat etamap56.tar.gz | tar xvf -

Make sure that you don't get any error messages saying "permission denied". If this is the case, then do the following:

% cd $NAWIPS/gempak
% chmod -R 755 help parm pdf

Then repeat the installation as indicated above.

You must now build etamap as you would any other gempak routine.

To run the program:

roz@kielbasa-> etamap
GCENTER Lat-lon center 39.0;-108.0
GSPACE Model grid spacing 0.098
IMJM Model Grid points 55;91
MAP Map color/dash/width 23//2
TITLE Title color/line/title 1/-2/WORKSTATION ETA DOMAIN
LATLO Line color/dash/width/label/inc 18/10/1/1;1/2;2
TEXT Text size/font/width/hw flag 1/33//HW
DEVICE Device|name|x size;y size|color XW
CLEAR Clear screen flag YES

A help page is provided. Simply type "help etamap" at the gempak prompt.

You can also get help on any of the other parameters (GCENTER, GSPACE, IMJM, etc, ) by also typing "help <parameter>" at the prompt.
