As the following code shows, when I read this raster for the first time, xarray can read its content correctly. When this raster is modified, it can't be read correctly. ### What did you expect to happen? _No response_ ### Minimal Complete Verifiable Example ```Python import rasterio import xarray as xr import numpy as np import os data = np.arange(10*10.).reshape(10, 10) inp_rs = ""demo.tif"" def generate_raster(data): with rasterio.open( inp_rs, 'w', driver='GTiff', height=data.shape[0], width=data.shape[1], count=1, dtype=data.dtype, crs='+proj=latlong', ) as dst: dst.write(data, 1) generate_raster(data) rs1 = rasterio.open(inp_rs) print(""rasterio :"", rs1.shape) rs2 = xr.open_dataset(inp_rs) print(""xarray: "", rs2.band_data.shape) # modify it os.remove(inp_rs) data_new = np.arange(9*9.).reshape(9, 9) generate_raster(data_new) rs1 = rasterio.open(inp_rs) print(""rasterio :"", rs1.shape) rs2 = xr.open_dataset(inp_rs) print(""xarray: "", rs2.band_data.shape) ``` ### MVCE confirmation - [X] Minimal example — the example is as focused as reasonably possible to demonstrate the underlying issue in xarray. - [X] Complete example — the example is self-contained, including all data and the text of any traceback. - [X] Verifiable example — the example copy & pastes into an IPython prompt or [Binder notebook](https://mybinder.org/v2/gh/pydata/xarray/main?urlpath=lab/tree/doc/examples/blank_template.ipynb), returning the result. - [X] New issue — a search of GitHub Issues suggests this is not a duplicate. ### Relevant log output ```Python Read correctly the first time: rasterio : (10, 10) xarray: (1, 10, 10) Incorrectly read the second time: rasterio : (9, 9) xarray: (1, 10, 10) ``` ### Anything else we need to know? _No response_ ### Environment
