shr_map_getWts error for a single point simulation

[koichi_sakaguchi@pnnl_gov]

I am trying to run CLM4 for a single point with my own surface and atmospheric forcing data.
I have made the required surface forcing data sets with "getregional_datasets.pl"
For atmospheric forcing, I downloaded an example monthly forcing data for Vancouver, Canada and changed its lat, lon, and grid edges to be the same as the surface forcing data for testing. The coordinates look like:

atmo (clm1pt-0000-01.nc) surface
EDGEN -1.894737 -1.89473684210535
EDGES -3.789474 -3.78947368421061
ESGEE 306.25 306.25
EDGEW 303.75 303.75
LATIXY -2.842105 -2.84210526315798
LONGXY 305 305


But I get this error message at runtime.

('shr_map_getWts') ERROR: yd outside bounds -2.84210526315798
(shr_sys_abort) ERROR: ('shr_map_getWts') ERROR yd outside 90 degree bounds

Somehow the subroutine shr_map_getWts complains that my latitude coordinate is beyond + or -90 degree bounds, but they are obviously not.

If anyone knows how to solve this problem, please let me know.

Thanks,

Koichi
