This dataset presented here is a timeseries version of the CDS AgERA5 dataset on approximately 0.1° x 0.1° resolution and is stored in Analysis Ready Cloud Optimised (ARCO) format, which has been implemented for retrieving long time-series for a single point in a efficient way. The AgERA5 data version used to produce the dataset is v2.0.

Methodology

Excerpt

The process to generate this dataset involves:

  • Fetching AgERA5 data in netCDF format.
  • Ensure only files with version 2.0 are ingested
  • Applying homogenization conventions, as applicable:
    • Ensure latitude, longitude ranges are between [-90, +90], [-180, +180].
  • Writing to an ARCO Zarr archive (which is similar in structure to netCDF).
  • The CDS requests the data from the Zarr archive using xarray and writes the data to netCDF or CSV (as requested).
