set_options is applied on init, not enter

Really nice stuff! I'm not impacted by this, but I noticed a bug. In the following example, I would expect corresponding options to be applied to operations on their corresponding...

Support query

This is kind of inspired by the way we handle weights. The weights must be `DataArrays` for `xarray`, but `cf_xarray` allows strings so we can do `cf.weighted('volume')`. How about introducing...

hvplot accessor?

1

As mentioned by @dcherian in https://github.com/xarray-contrib/cf-xarray/issues/101#issuecomment-705214357, it would be cool to have an accessor for hvplot, which would hopefully identify lon/lat coordinates in hvplot removing the need to enter them...

should guess_coord_axis optionally create a variable for unindexed coordinates

1

```python da = xr.DataArray(np.ones(2,3), dims=("x", "y")) ``` This kind of dataarray exists in CMIP datasets. `x,y` have absolutely no data (no values, no attrs) associated with them, and so `guess_coord_axis`...

item assignment

Couldn't see an issue open for this. It may also not be in the roadmap. ``` import xarray as xr ds = xr.open_zarr("s3://era5-pds/zarr/2021/01/data/air_temperature_at_2_metres.zarr").isel(lat=0, lon=0) # coord named time0 with standard_name:...

In recent years, [Semantic Web](https://en.wikipedia.org/wiki/Semantic_Web) technologies have been used to record the data processing steps involved in producing climate products (i.e. maps, plots or any other climate research outcome stored...

This builds on @dcherian work to track history and cell_method and adds basic provenance tracking. https://github.com/xarray-contrib/cf-xarray/issues/228#issuecomment-909787315 It's inspired by what [metaclipR](https://github.com/metaclip/metaclipR) is doing. Things to do: - [ ] xarray:...

Add attribute tracking functionality

3

Simple test of https://github.com/pydata/xarray/pull/5668 (cc @keewis) This just adds the `cell_methods` attribute for reductions and a placeholder for tracking history. ``` python import cf_xarray as cfxr import xarray as xr...
