I want the North Atlantic Oscillation (NAO) index data for all the CMIP5 or AR5 GCMs in monthly or seasonal format during 1901-2015. Please suggest me a data archive to get this data.
Hi Jitendra... You can download SLP fields from ESGF database (https://esgf-index1.ceda.ac.uk/search/cmip5-ceda/) and subtract values from 37.7°N, 25.7°W (Azores) and 65.1°N, 22.7°W (Iceland).
