I started following links the Wikipedia page on the General Circulation Model and tried to get to what data the IPCC had on HadCM3 experiments. One would think this data is free for all and had been archived. I sure did find a link to "The UPCC Data Distribution Centre" but had no luck accessing the data.

When I go to the first link, and try to download the first GZIP/GRIB file, I getThis is the HadCM3 (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 Run
 HC3CI
 (constant CO2)
 a Greenhouse Gas Integration
 HC3GG ,
historical and IS95a, with specification of CO2 and various minor gases individually
 an all-anthophogenic forcing Integration
 HC3AA ,
greenhouse gas, plus the direct and first indirect effect of sulphate aerosols, and ozone changes
Data from these experiments have already been widely distributed by the Climate Impacts LINK Project.
