How to Create Station Data from Grid Data

[Srinivas Desamsetti]

Dear Sir,
Thank you very much for your reply.
But still I cannot get clear idea how to use gr2stn function in GrADS.
I fixed latitude, longitude and varied the time dimension.
and I gave  a command

d gr2stn(u,83.14,17.42)
It gives the error like "Invalid Stn Data Dimension Environment".

I request you to kindly suggest me to solve the problem.
I will be so thankful for your help.
Thanking you
Best regards
Srinivas

Hello,
   I believe what you can use is the gr2stn() function built into Grads (more info http://www.iges.org/GRADS/GADOC/gradfuncgr2stn.html).  Essentially you'll type into the Grads command line: gr2stn(grid variable, lon, lat) and it will output a station value for you.

Dear Sir/Madam,

I have a gridded data and I can plot the variables.
I want to get the Data at one Particular Latitude and Longitude (ie) for a station.

When I give 'set lat 12.42' it is taking at 12N as I have 1 degree data.

So, I request you to suggest me to get an interpolated value to a particular
lat/long (Station) from the Gridded data.

Thanking you

Srinivas
