[gradsusr] Gridding and Plotting Station Data

[Nena Carina Española]

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,

Nena
