possile problem with merging files getting inconsistent verificaion time

Added by cynthia hays about 11 years ago

Hi,

I seem to be having problems with merging two files. My original files are netcdf and I think I have transformed them to grb correctly (inverting levels, getting hybrid levels coefficients and a z-axis description file). When I merge orog.grb and temp4.grb to temp5.grb (cdo -t echam6 merge orog.grb temp4a.grb temp5a.grb) [The files were not echam6 originally they were MICROC5 but I was trying to use the grib codes for echam6 since I had worked a little with echam6 before.] when I do any commands with temp5.grb I get Warning (cgribexScanTimestep1) : Inconsistent verification time (param=134 level=0). I was trying to get enough variables in a file to get pressure levels using ml2plx for the air temperature, u and v windspeed components, specific humidity and geopotential height. I've attached the 3 files (I've reduced them to one timestep). My version of cdo is CDO version 1.5.6.1

Any help with this will be appreciated and if you need anymore information please let me know

Download all files
temp4a.grb (12.6 MB) temp4a.grb
orog.grb (64.1 KB) orog.grb
temp5a.grb (12.7 MB) temp5a.grb

Hi,

It seems this is not a problem with merging files, although depending on the merge order you get different variables/param's forWarning (cgribexScanTimestep1) : Inconsistent verification time.

I'm still having problems with using ml2plx I keep getting warnings
cdo ml2plx (Warning): Orography (surf. geopotential) not found - using zero orography!

cdo ml2plx (Abort): Temperature not found, needed to compute geopotheight!

I'm pretty sure I do have 129 surf. geopotential in the file so I'm somewhat at a loss as why I am getting this warning?

Obviously I'm missing something? Any ideas what I am doing wrong?

Thanks

Cindy

I think, the error is due to the fact that the parameter table number may different from the ECHAM5 table number. you could set the same with "setparam" (e.g. cdo -setparam,129.128 ...) please have a look at

Thanks for the quick answer I changed 129 to 128 put that didn't work either same problem.

cdo ml2plx (Warning): Orography (surf. geopotential) not found - using zero orography!

cdo ml2plx (Abort): Temperature not found, needed to compute geopotheight!

sorry, that was my mistake. you should have tried with "setpartab"

for example, for 1000,850,500 ...hPa

cdo -ml2plx,100000,85000,50000,30000,20000,5000 -setpartab,echam5 temp5a.grb ofile.grb

hope this helps,

Cheers,
J
