MM5toGrADS

[Hristina Kirova]

Hi,

I am trying to run MM5 with 5 domains and I have problem with the
finest one.But when I tried to vizualize DOMAIN5 with GrADS, using
MM5toGrADS there is something strange with specific longitudes around -
112.For example

ga-> set lon -112.2
LON set to -112.202 -112.202
ga-> d t
Data Request Error: Invalid grid coordinates
World coordinates convert to non-integer grid coordinates
    Variable = t  Dimension = 0
  Error ocurred at column 1
DISPLAY error:  Invalid expression
  Expression = t

The same is situation with longitudes  -112 and -112.1.These longitudes
are  in the middle of the domain5 and there are not inside of  particular
grid cell.All other data for different from these lon are OK.
I sent my problem to mm5 users list but they wrote to me that there is
nothing wrong with my MMOUT_DOMAIN5 file and it is may be a problem
which have to be send to the grads users list.
In MM5toGrads there is a possibility to prepare a GrADS file only for 1
point.So I used
ga-> query w2gr -112 33
Xdim = 178.778  Ydim = 21.0001

and put this values in mm5_to_gradsc.csh:
............................
IFSKEW=1
! IFSKEW=0 will write fully 3-D data
! IFSKEW=1 will write out data at 1 grid point only.
ISKW=178.778 ! the i point (in N-S direction)
JSKW=21.0001 ! the j point (in E-W direction)

..............

and with so created file it is possible to be ploted  different variables.

I put my MMOUT_DOMAIN5.gz on ftp://ftp.meteo.bg/incoming/

Can someone help me to solve this problem?

Thank you very much

Hristina
