SO&P: HadCM3 data and information

Important notes regarding the HadCM3 data:

Do not redistribute data to others outside the SO&P project.

Hadley Centre will require co-authorship and need to know from the start what analyses you are using the HadCM3 data for. Please contact Simon Tett (see SO&P participants table) and keep him informed.

To ensure collaboration between SO&P partners, please refer to the list of ongoing/planned model-data comparisons. Please contact others who have listed an interest in the same area, to initiate collaboration. To add your planned areas of model-data work to the list, email Tim Osborn.

A small climate drift, unrelated to the external forcings, is present in the HadCM3 simulations. It's significance depends on the region and variable being considered. Simon Tett describes how this should be dealt with, by reference to the HadCM3 control simulation, in this report (not yet available). The HadCM3 control simulation data is not yet available.

Please inform Tim Osborn of any errors that you find in the data.

Simulations available:

control : 1243-2252 constant forcings
nat : 1500-1999 natural forcings only
all : 1750-1999 all forcings
