Opening virtual datasets with NASA dmrpp files

1

The idea is to speed up opening up netcdf4/hdf5 datasets with a NASA specific optimization. Load data like `xr.open_mfdataset` with kerchunk/zarr speeds by translating **existing dmr++ metadata files to zarr...

Integrate the virtualizarr dmr++ parser into pydap

2

### Description There have been some discussions to have the `virtualizarr` dmrpp parser as a part of`pydap`. This would be beneficial since the parser can make sure to maintain strict...

open_virtual_dataset returns some coordinates as data variables

1

The `xr.Dataset` constructed by `open_virtual_dataset` doesn't seem to correctly identify coordinates when the coordinate has more than one dimension. The bug seems to be in `separate_coords` [on this line](https://github.com/zarr-developers/VirtualiZarr/blob/f60707f86f6fa7415463c1a3e886eb134b84bdb0/virtualizarr/xarray.py#L363). The...

Datetime coordinate missing single timestep (NaT) when data is loaded

1

I was trying to virtualize references and then load some NASA MERRA2 data offered at GESDISC. I noticed that when the dataset is loaded using the references made by virtualizarr,...

Original comment: https://github.com/zarr-developers/VirtualiZarr/pull/265#issuecomment-2456072544 There is some code in `from_kerchunk_refs` which creates a ZArray with `fill_val = np.nan` as the default value which does not match the default value set in...

Refactor `open_virtual_dataset` and `open_virtual_mfdataset` API to match `virtualizarr`

1

Currently `earthaccess.open_virtual_mfdataset` is implementing some logic that should be in virtualizarr. We should remove this logic from earthaccess and simplify the current implementation. Then the earthaccess API will only add...
