To generate this ERA5-land hourly time series dataset, homogenisation conventions have been applied to the ERA5 source GRIB 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 see details below. The dataset presented here is a subset of selected parameters from the full CDS ERA5 hourly data on single levels (1940–present). Requirements for additional parameters may be considered. Please raise your request with ECMWF Support here |
Please be aware that the generation of this dataset is using an alternative source for the ERA5-land data and may be subject to changes over time (e.g. file format, data file structure, deprecation etc). This dataset should therefore be regarded as “experimental” and is not recommended for use in a production environment. Notification of changes via the catalogue entry warning banner and/or in the Forum will be provided on best efforts

Introduction
ERA5-Land is a reanalysis dataset providing a consistent view of the evolution of land variables over several decades at an enhanced resolution compared to ERA5. It covers the period from January 1950 to the present with hourly sampling and continues to be extended forward with 5 days behind real time.
