Hi Arlindo,<br>
<br>
I already saw that recipe and the data used there is annual. Mine's
hourly. Can I use it with hourly data? If yes, is there something I
need to change in my data to make the recipe work?<br>
<br>
Thanks,<br>
<br>

I am still figuring out how to convert my station data into
GrADS binary as I am very new to GrADS. I already posted my
problem yesterday but nobody has answered it yet. <a

I do not know how to create a binary with more than one
surface variable. I was able to create a binary for one
variable only and most examples I find use only one
variable. Now I have three, and data is hourly. Here's a
sample:<br>

<pre>Hi Nena.
Here a simple formula to have U and V in m/s from wind speed (velv) and direction (dirv):
'set gxout barb'
'd -velv*cos((dirv-90)/180*3.14);-velv*cos(dirv/180*3.14)'
To display these data with OACRES function first you must create a base grid file
with a "dummy" constant value for example and then you can interpolate wind data:
'vel=oacres(dummy.1,velv.2,4,3,3,1)'
'd vel'
'run <a moz-do-not-send="true" href="http://cbarn.gs" target="_blank">cbarn.gs</a>'
Good luck.

Oggetto: [gradsusr] Visualize Wind Vectors
Hello Guys!
I am trying to create a visualization of the wind vectors. I am not sure where to begin as my data is not split into U and V components. Here's a snippet of the sample data I have. These are from 24 weather stations in the Philippines. Can I also interpolate these scattered data to create a gridded data using the OACRES function?
Station ID Latitude Longitude Wind Speed (m/s) Wind Direction (degrees)
12 15.721279 121.522293 0.8 204
70 7.135233 124.814758 2.21 148
72 6.960916 126.212082 6.34 286
73 9.282162 123.244572 9.6 20
74 8.997093 124.883595 1.54 85
75 9.217067 124.713134 3.84 89
Thanks,
Nena
