wrong grid for LM external parameters for ERA5
Dear all,
I am trying to downscale ERA5 cas files using cosmo. I run into an error using int2lm_2_clm4, I tried the suggestions posted in the forum (such as changing startlon_tot by 0.001) but it still didn’t work. I made sure that
EXTPAR
domain is larger than my requeted LMout. I hope you can help me.
Thank you very much.

The grid you defined in LMGRID is within the area of the external data set and has the same grid mesh size, however, the nots of the LMGRID are shifted relativ to the external data set grid nots.
