The merged Hadley-OI sea surface temperature (SST) and sea ice concentration (SIC) data sets were specifically developed as surface forcing data sets for AMIP style uncoupled simulations of the Community Atmosphere Model (CAM). The Hadley Centre's SST/SIC version 1.1 (HADISST1), which is derived...

Directly measured and continuous records of atmospheric carbon dioxide (CO2) extend back to 1958. CO2 has also been measured in ancient air samples trapped in ice cores, and these records extend back hundreds of thousands of years. More recently, CO2 is being sampled by satellites providing global...
