Hi Croco community,

I am trying to setup a new region with interannual forcing by following the same technique as in Benguela case.

I have downloaded the CFSR raw netcdf files and I am running the script for the variables:

varnameCFSR=(\ DSWRF_L1_Avg_1 \ DLWRF_L1_Avg_1 \ ULWRF_L1_Avg_1 \ USWRF_L1_Avg_1 \ U_GRD_L103 \ V_GRD_L103 \ PRATE_L1_Avg_1 \ TMP_L103 \ SPF_H_L103 \ TMP_L1 \ )

varnameCROCO=(\ Downward_Short-Wave_Rad_Flux_surface \ Downward_Long-Wave_Rad_Flux \ Upward_Long-Wave_Rad_Flux_surface \ Upward_Short-Wave_Rad_Flux_surface \ U-component_of_wind \ V-component_of_wind \ Precipitation_rate \ Temperature_height_above_ground \ Specific_humidity \ Temperature_surface \ )

The script works fine and generates the monthly nc files for some variables (e.g. Downward_Short-Wave_Rad_Flux_surface, Downward_Long-Wave_Rad_Flux, Upward_Long-Wave_Rad_Flux_surface, Upward_Short-Wave_Rad_Flux_surface, Precipitation_rate) but it fails for other variables (e.g. U-component_of_wind, V-component_of_wind, Temperature_surface)

I have checked the raw CFSR files for correct variable names and for temporal range and both the names and the times are correct.

But I am getting the following error: ... in file double free or corruption (out) ./ line 193: 47992 Aborted ncwa -O -a record ${var}_${ffile} ${var}_${ffile}

Any ideas where the error is coming from?

P.S. I am using the latest version of CROCO 1.2.1 and croco tools. Regards Konstantinos

I noticed in the script the option: ncwa -O -a record ${var}_${ffile} ${var}_${ffile} # <<<< the problematic line

other way to define the dimension as unlimited dimension

ncks -O --mk_rec_dmn $time_dim ${var}_${ffile} ${var}_${ffile} # <<<<<< alternative way

So I commented out the problematic line and uncommented the alternative line and it seems to overcome the error. But I still have to check and run the CROCO monthly netcdf generated files to make sure they are working properly.
