It should look something like this: min_lon = -24.995 Now, you can create the mask for indexing purposes using the extent. You can see that it has 275 columns on x and 205 rows on y as well as xc and yc coordinates (which have a different name on your dataset).

One way is to create a boolean mask for the dataset coordinates using the extent you specified and then using the. What is the correct xarray way of cropping a large raster to a given lat/lon window? I tried to use xarray's filters and subsetting, but it seems I am doing something wrong, since I can't get the required slice: # Example 1īoth of them produce: KeyError: 'not all values found in index 'x'' So, as you can see, the longitude and longitudes are stored under the 'x' and 'y' coordinates and they come in WGS84 (EPSG:4326) format. The raster file description looks like this: I have seen some examples here and here trying to make this operation I am describing, but it seems they are not working in this case. Turns out that the extent of this raster file is too big to combine it with other layers, so I would like to crop it to a given extent specified in lat/lon coordinates. I have a netcdf file showing elevation over Europe derived from GTopo30.
