TLONG (nlat, nlon) float64 320.6 321.7 322.8 323.9 325.1 326.2 327.3 ... Dimensions without coordinates: nlat, nlon Attributes: long_name: area of T cells units: centimeter^2 In [6]: advt = xr.open_dataarray('advt.nc') In [7]: advt Out[7]: <xarray.DataArray 'ADVT' (nlat: 384, nlon: 320)> [122880 values with dtype=float64] Coordinates: TLAT (nlat, nlon) float64 -79.22 -79.22 -79.22 -79.22 -79.22 -79.22 ...

Dimensions without coordinates: nlat, nlon In [8]: advt * tarea Out[8]: <xarray.DataArray (nlat: 384, nlon: 320)> array([[ nan, nan, nan, ..., nan, nan, nan], [ nan, nan, nan, ..., nan, nan, nan], [ 8091417.091781, 15948194.682816, -49201736.790674, ..., nan, nan, nan], ..., [ nan, nan, nan, ..., nan, nan, nan], [ nan, nan, nan, ..., nan, nan, nan], [ nan, nan, nan, ..., nan, nan, nan]]) Dimensions without coordinates: nlat, nlon ``` TLAT and TLONG are gone. Any suggestion? Here I provide my test data. |
