Error trying to concatenate a number of nc files

[jbensabat]

Hello
I am trying to concatenate a number of files that all have identical structure (See picture).

I get error (-57) "start + count exceeds dimension bound" on variable u10
I cant figure out where the error is as these files are generated automatically (via the EU Climate Data Shop ERA5-LAND)

Hi
thanks for the hint
Assume that I have two netcdf files with a structure that is identical to the one in the picture above.
The only difference is that the times are different.
when I apply ncecat to these two files, ncecat does not merge the variables but adds another dimension

for example if I have ISRAEL_METEO_2010_01_01_04.nc with 96 time steps dimension of u10 for example is 96X40X18

and file ISRAEL_METEO_01_01_05_08.nc with 96 other time steps with variable u10 having the dimensions 96X40*18

ncecat will create a variable u10 with 4 dimensions instead of fully merging the values in u10

this instead of having u10 with dimensions 141X40X18

I guess I am using the wrong function or option. Is there a way to merge files, the variables in the files instead of putting them together ?
thanks

It sounds like you need to use ncrcat instead of ncecat. The manual explains the differences here.

Hi
thanks - I figured that out for the docs
the problem is that ncrcat does not seem to be included in the distribution or at least not under this nam e

If you do not have the ncrcat executable you can run ncra -Y ncrcat ... instead. Or you can copy ncra.exe to ncrcat.exe. It's one executable that behaves differently depending on how it was invoked.
