these two should equals ,but not , latitude was wrong

import numpy as np import xarray as xr data1 = xr.open_dataset('test1111111.nc') ```

wrong code

np.array(data1.sel(time='1990-1' , isobaricInhPa=200 ).z[: , ::-10 , ::10]) Out[37]: array([[[109890.25, 109890.75, 109890.75, ..., 109888.25, 109889.25, 109889.75], [110014.75, 110017.75, 110020.75, ..., 110006.75, 110009.75, 110012.25], [110109.75, 110115.25, 110119.75, ..., 110098.25, 110101.75, 110106.25], ..., [107800.25, 107824.75, 107845.75, ..., 107719.75, 107747.25, 107775.25], [107684.25, 107697.75, 107709.75, ..., 107641.25, 107656.25, 107670.25], [107585.75, 107587.75, 107589.75, ..., 107578.75, 107581.25, 107583.25]]], dtype=float32) ```

right code
