Hello All,

This question is slightly related to grads program but not entirely.  But seeing 
that most of the users work with Climate Models, I was hoping that I would get 
some response to my questions.

I have produced the precipitation output from GCMs using the GraDs program.  The 
precipitation variable is in units kg/m2/sec.  Can anyone tell me how I can 
convert this to the units I need, which is inch/month?

Thanks
Spandana

Somebody sent you the answer before:

1 kg/m2  = 1 mm

the rest (the time scale and the change to inches)
you should be able to figure it out...

Dear GrADS users,
I want to run xcbar for a precipitation map VERTICALLY. I have a script for
this purpose
that work horizontally but I do not know how to use it in vertical form.

Any Idea?

Thanks in Advance

Hello,
I'm having some problem with cropping and subsetting GRIB files.
I found lats4d script very useful for that, but there is some annoying error it 
makes - in the resulting GRIB file it writes the wrong variable names (while in 
the resulting CTL file they are correct).

For example, I'm taking the lfff00120000p GRIB file (attached, together with its 
CTL and IDX),
and it has 5 fields inside: fi, omega, relhum, t, u, v.
You can see it in the attached lfff00120000p.ctl file, as well as by running 
"wgrib lfff00120000p".
Then I'm trying to extract only 2 fields, e.g. fi and t, to reduce the domain 
size, and to dump the result into a new GRIB file.
To do that, I'm using the following command:

lats4d.sh -i lfff00120000p.ctl -o lfff00120000p_crop.grb -format grads_grib -lat 
29 33.5 -lon 34 36 -vars fi t

This command generates 3 new files: lfff00120000p_crop.grb, 
lfff00120000p_crop.ctl and lfff00120000p_crop.gmp (attached as well).
The resulting GRIB file seems to be valid, and the CTL file looks absolutely 
fine!
But when I try to run "wgrib lfff00120000p_crop.grb", instead of fi & t, I see 
PRES & PRMSL variables!
My guess is, that the lats4d script is in some way unaware of the fact that the 
original GRIB file is encoded according to Offenbach (center code 78) GRIB 
table, but I don't know how to define it.

Any help would be highly appreciated!
Thanks!
Alon.

P. S. some aditional technical info, don't know if it's relevant:

lats4d Version 2.1.5

Grads v2.0.a9.oga.1
