Xarray backend to map an ECMWF style request to a service onto an Xarray Dataset
This Open Source project is build by B-Open - https://www.bopen.eu
xarray-ecmwf is a Python library and Xarray backend with the following functionalities:
- opens an ECMWF style request as a Xarray Dataset connected to the remote services
- the Climate Data Store via cdsapi: ERA5, Seasonal forecasts
- the Athospheric Data Store via cdsapi
- the ECMWF Open data via ecmwf-opendata: High resolution forecasts, ensemble forecast
- allows lazy loading the data and well integrated with Dask and Dask.distributed
- allows chunking the input request according to a configurable splitting strategy. Allowed strategies:
- by one month
- by one day
- supports requests returning a single GRIB file, via cfgrib
>>> import xarray as xr
>>> request = {
... "dataset": "reanalysis-era5-single-levels",
... "product_type": "reanalysis",
... "variable": ["2m_temperature"],
... "year": ["2002"],
... "month": ["01"],
... "day": ["15"],
... "time": ["00:00", "12:00"],
... }
>>> ds = xr.open_dataset(request, engine="ecmwf")
>>> ds
<xarray.Dataset>
