grads script

[Eric Altshuler]

The last command given below is not valid:

d hgt.5(lev=500, time=3, lon.4,lat.4)

First: the time specification should be t=3, not time=3. Using "time=<value>" requires an absolute time specification, such as "time=00z24sep2009".
Second: lon.4 and lat.4 are not dimension specifications. The command should be something like this:

d hgt.5(lev=500,t=3,lon=<longitude value>,lat=<latitude value>)

Hi Tanusri !

When you work with multiple files, each variable of a file can be poltted adding a point and a numbre of a file opened, for example:

If you wanto to plot geopotential heights of a file 1 just do:

d hgt.1

If you want to plot geopotential heights of file 2 in level 500 Hpa just do:

d hgt.2(lev=500)

If you want to plot geopoential heights of file 3 in level 500 and time 2 justo do:

d hgt.3(lev=500,time=2)

If you want to plot gepotential heights of file 4 in level 500, time 3, lon -33 and lat -70, justo do:

d hgt.4(lev=500, time=3, lon=-33,lat=-70)

If you want to plot gepotential heights of file 5 in level 500, time 3 and the lon and lat applied to file 4, justo do:

d hgt.5(lev=500, time=3, lon.4,lat.4)

sir/madam,
I am doing research in IITM,Pune,India. I want do some ploting on grads. the
problem is that I want to open more than two nc file which contaning same variable say
OLR. so i want to average that variable from those different file grid wise and plot
one average graph.
Thanking you.
