run 'grads -l'
open wrf.ctl
set gxout shaed
set csmooth on
d slvl.1

and you will see the background color as shown in the example

set lon -43.75 -43.1
set lat -23.1 -22.7
d slvl.1

and it zooms into the area where the data points can be plotted

Subject: [gradsusr] Gridding and Plotting Station Data

Hi Guys,

First of all, I'm not a meteorologist so pardon me if my questions here might sound silly to you. :-)

I need help with Recipe-013: Gridding and Plotting Station Data<http://cookbooks.opengrads.org/index.php?title=Recipe-013:_Gridding_and_Plotting_Station_Data>. What I need to do is to be able to plot contour maps from hourly AWS data, just like what was done in Recipe-013. However, I won't be plotting just precipitation. I'll just start out with pressure. Later on if I already know the ins and outs of this recipe, I'll be creating plots for other variables such as temperature, wind speed, and wind direction.

We have a team in charge of parsing the information from AWS and could feed me data that's already been formatted to what Recipe-013 requires. Following the recipe, I was able to create a control file and binary that GrADS could read. What I don't understand is the wrf.dat and wrf.ctl that the recipe is using. The recipe says it "contains any forecasted variable and, most important, the information of the grid we want the station data to be gridded to." Can someone explain this further to me? I was only asked to plot actual data, no forecasting or whatsoever. :-)

Thanks and regards,
