There is nothing wrong with your data.
The coordinate are monotonically increasing 1D arrays.
Most of it seems to be missing [_FillValue].
Note that your data does have the cyclic pt
included [lon=361 , -180 to +180]
^
The gsn_csm* suites of map functions assume that
there is no cyclic pt. It implicitly adds the
cyclic [wrap around] point.
Try:
res@gsnAddCyclic = False ; data already has cyclic pt
Perhaps, u might want to turn on Raster mode
res@cnFillMode = "RasterFill" ; Raster Mode
