<p class="MsoNormal">Hi John. Thanks for the reply.<br>
<br>
The recipe was derived from the operational procedure of Brazil and we wanted
to adopt a similar procedure for the Philippines. I am from the IT sector so
I'm really new to all of these. What I actually wanted to ask about is the
numerical model data itself. I don't have that. I only have observed data from
AWS network. Can I actually use the wrf.dat that came with the recipe or do I
have to create my own from WRF? <span class="moz-smiley-s1">:-) </span><br>
<br>
What our team wants is to be able to visualize the hourly data we have for
temperature, humidity, pressure, wind speed, wind direction, solar radiation,
and hourly rain. But our priority is pressure, wind speed, and wind direction.
If you know of other techniques/recipes that I could follow please let me know.
<br>
<br>
Thanks and BR,<br>

<p class="MsoNormal" style="margin-bottom: 12pt;"><span style="font-size: 10pt; font-family: "Tahoma","sans-serif";">Hi Guys,<br>
<br>
First of all, I'm not a meteorologist so pardon me if my questions here might
sound silly to you. :-)<br>
<br>
I need help with <a href="http://cookbooks.opengrads.org/index.php?title=Recipe-013:_Gridding_and_Plotting_Station_Data" target="_blank">Recipe-013: Gridding and Plotting Station Data</a>. 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.<br>
<br>
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. :-)<br>
<br>
Thanks and regards,<br>
<br>
Nena</span></p>
