A CLI utility to print metadata of datasets in various formats (e.g. NetCDF, zarr, GRIB etc)
powered by xarray
You need the following binary dependencies:
- Python >= 3.9
- Optionally, eccodes, which is necessary for GRIB support.
The recommended way of installation is pipx:
pipx install inspectds
or if you want support for GRIB, SELAFIN or both:
pipx install 'inspectds[grib]'
pipx install 'inspectds[selafin]'
pipx install 'inspectds[all]'
If you want to install the latest development version from git, then use:
pipx install 'git+https://github.com/pmav99/inspectds.git#egg=inspectds[all]'
