Access to the HadCM2 (HCCPR) experiments


This is the HadCM2 (HCCPR) experiment page. From here you can take the choice between the experiments listed below. Afterwards you have to decide which variables you need and which data format you prefer. Finally, you will be guided to the files themselves. Up to now, these experiments are available

a Control Integration
(constant CO2)
an ensemble of 4 Greenhouse Gas Integrations
HCGGa1 , HCGGa2 , HCGGa3 and HCGGa4 .
(historic CO2 1860 - 1989, 1 % compound increase 1990 - 2099)
an ensemble of 4 Greenhouse Gas Integrations
HCGGd1 , HCGGd2 , HCGGd3 and HCGGd4 .
(historic CO2 1860 - 1989, 0.5 % compound increase 1990 - 2099)
an ensemble of 4 Greenhouse Gas plus Sulphate Integrations
HCGSa1 , HCGSa2 , HCGSa3 and HCGSa4 .
(historic CO2 1860 - 1989, 1 % compound increase 1990 - 2099,
additionally historic SO4 1860 - 1989, IS92d 1990 - 2099)
an ensemble of 4 Greenhouse Gas plus Sulphate Integrations
HCGSd1 , HCGSd2 , HCGSd3 and HCGSd4 .
(historic CO2 1860 - 1989, 0.5 % compound increase 1990 - 2099,
additionally historic SO4 1860 - 1989, IS92d 1990 - 2099)

Ensemble simulation means that a number of runs with identical forcing, but with different initial conditions, are performed. In this case the runs of each ensemble initialised at periods 150 years apart on the control run. A schematic of the conceptual structure of the Hadley Centre's ensemble simulations can be seen here.

Data from these experiments have already been widely distributed by the Climate Impacts LINK Project.
