Poles Apart: Why has Antarctic sea ice increased and why don't coupled climate models reproduce observations, climate model data

Data produced in support of the NERC project Poles Apart (2014 - 2017) that investigated the atmospheric drivers of changes in surface wind forcing using the UK Chemistry and Aerosols (UKCA) model.

Ten HadGEM3 model simulations were undertaken. Monthly model data was taken from the final 30 years of each simulation and a number of variables of interest, e.g. temperature and precipitation were extracted and analysed.

The temporal range for the perturbed simulations is 1980-2013, and the control simulations are valid between 1841-1900.

See the detailed experiment documentation for the Unified Model experiment ids and their corresponding description (these have been used to organise the data).
