We are pleased to announce that a new dataset has been published today, 01-06-2026, in the Climate Data Store (CDS):
This dataset is a post-processed version of the original CDS Agrometeorological indicators from 1979 to present derived from reanalysis (AgERA5) and is stored in Analysis Ready Cloud Optimised (ARCO) format, which has been designed for fast access long-timeseries for a single point or a 5°x 5° area.
To generate this AgERA5 time-series dataset, homogenisation conventions have been applied to the original data to ensure consistency, usability, and alignment across chosen variables and time steps. The processed data were then written to an ARCO Zarr archive, enabling efficient cloud-optimised access and scalable data retrieval. Please refer to the user guide for details.
This dataset offers:
- interactive access to the data files using the AgERA5 Time-series Download form
- programmatic access to the data files using CDS API service
- NEW - programmatic access to the full AgERA5 time-series without downloading individual files (analysis-ready Zarr stores) - please refer to instructions provided on the new Analysis Ready Data tab. Please note that this is a Beta service . Data Store Service administrators reserve the right to take the necessary actions at any moment, including closing access to maintain the overall performance of the Data Store Service.
