problem with INT2LM for EURO-CORDEX domain

Added by Edoardo Bucchignani about 8 years ago

Dear all,
I am trying to perform a simulation over an enlarged EURO-CORDEX domain, extending until 43.23 degrees north, using a rotated pole (-162, 39.25) and forced by ERA-Interim.
Unfortunately, I am obtaining an error message in INT2LM, reported below.
I suppose it is a problem related to the ec_ext.nc file (which is equal to one of the ERA-Interim cas files).
Attached please find the namelist used.
Could please help me ?
Best regards
Edoardo

It seems that your domain crosses the North Pole. The ECMWF data end at 89.4628219604492 North and 179.296875000000 East. In order to fill the “gap” to 90 North and 180 East you need to set in namelist GRID_IN:

north_add_in=1, east_add_in=1,

This internally copies the 180 West values to an additional column 180 East and the 89.4628219604492 North values to an additional pseudo row 90+(90-89.4628219604492) North.
