meteopendata2netcdf 0.3.0

Leverages open-data weather information via the NetCDF interface

meteopendata2netcdf

Leverages open-data weather information via the NetCDF interface.

Download ECMWF IFS open-data surface forecasts (temperature, wind, humidity) via ecmwf-opendata and export them to NetCDF.

Uses HTTP Byte-Range requests: only the bytes corresponding to the requested parameters and forecast steps are transferred, not the full GRIB2 files.

Installation

pip install meteopendata2netcdf

[!NOTE] eccodes must be installed on your system (required by cfgrib): apt-get install libeccodes-dev on Linux · brew install eccodes on macOS · bundled in the cfgrib wheel on Windows.

Quick start

from meteopendata2netcdf import IFSSurfaceDownloader

dl = IFSSurfaceDownloader(output_dir="./ifs_output")
result = dl.download()          # latest IFS run, GRIB2 + xr.Dataset
result.to_netcdf("ifs_surface.nc")
print(result.dataset)

# CLI
meteopendata2netcdf --output ./data/ifs --netcdf ifs_surface.nc
meteopendata2netcdf --source aws --time 0 --log-level DEBUG
