Domain near 180 date line. Problem with grid decompositon – in #10: INT2LM

in #10: INT2LM

<p> Your guess is right. The problem very likely lies in the longitude interval of the global model (-180, 178.125). The interpolation subroutine does only look for longitudes outside this interval. In your case a longitude larger than 178.125 is requested. To solve this problem add the following line in the <span class="caps"> GRID </span> _IN part of the namelist: <br/> <pre> east_add_in=1, </pre> <br/> This copies the first column of the input field to the end of the input field and such extends the interval to (-180, 180). <br/> A similar problem may appear for the poles. In these cases the corresponding parameters are north_add_in and south_add_in. </p>

east_add_in=1,

This copies the first column of the input field to the end of the input field and such extends the interval to (-180, 180).
A similar problem may appear for the poles. In these cases the corresponding parameters are north_add_in and south_add_in.
