agera5tools is a python package to manage AgERA5 including CDS downloads, file management and simple data access through an HTTP API. It simplifies using AgERA5 for applications that require time-series of AgERA5 variables for a given location and it avoids having to handle the large number of NetCDF files in which AgERA5 data is stored.
In June 2025 AgERA5 v2.0 was released. This version contains some important improvements/bug fixes and comes with a number of new variables in the dataset. However, due to these changes the current agera5tools v2.1 is not compatible with AgERA5 2.0 anymore. Since 18 August, a new version of agera5tools (3.0) is available on the Python Package Index which is fully compatible with AgERA5 v2.0. It can handle the new data layers available and has improved robustness in downloading files from the CDS.
I believe this release helps to improve the usability of the AgERA5 product for many applications. See the https://agera5tools.readthedocs.io for the user guide and other documentation.
