Hello,
I am trying to do a regional simulation where my land grid is 0.05 degrees resolution and rof grid is 0.125 degrees resolution. When I created the mapping file (lnd to rof and rof to lnd) to work with two different resolutions, the mapping files created but failed in grid check. I created the mapping files using the conservative and bilinear approach.
Run failed with the mapping file created by conservative interpolation and cpl log file showed that it stopped at the following lines:
(seq_mct_drv) : Initializing fractions
(seq_frac_check) [lnd init] afrac min/max = 1.00000000000000000 1.00000000000000000
(seq_frac_check) [lnd init] lfrac min/max = 1.00000000000000000 1.00000000000000000
(seq_frac_check) [lnd init] lfrin min/max = 1.00000000000000000 1.00000000000000000
(seq_frac_check) [rof init] lfrac min/max = -0.727638457703174923 1.67271132771549458
(seq_frac_check) [rof init] rfrac min/max = 1.00000000000000000 1.00000000000000000
Instead, I used the mapping file created using a bilinear approach which made the model run. However, I found in the output file that after a certain latitude, the volume of water stored in river (VOLR) is zero and no flow is adding to the main channel from the nearby small channels, and streamflows are not increasing in the downstream.
I checked QRUNOFF from the land model which seems resonable.
***Any idea how to make the mapping file using conservative interpolation (by ESMF) so that it doesn't fail in the grid check by ESMF Regrid Weight Check tool?
***How to deal with the problem of having zero VOLR after a certain latitude?
***I am assuming the error is due to the use of an inappropriate mapping file. Any other possible issue that I should look for?
Any insight/suggestion to solve the issue is appreciated.
Thanks
