The latest global reanalysis BRAN2020 was released in May 2021. The initial dataset spans 1993 to 2019; however, it is periodically extended to recent months. Currently, the dataset extends to the end of 2021.

External users can access the data at the NCI data catalogue. This provides a description of the dataset and access via a Thredds server.

A paper by Chamberlain et al. (2021) has further details and results.

Users of output are encouraged to join the BRAN-users Google Group. (Log into Google, then click ‘Ask to join the group’.)


The previous reanalysis BRAN2016 spanned January 1994 to August 2016. It has been superceded by BRAN2020.
