Simulations made with the ECHAM-HAM model as part of the PDRMIP project. Model version is ECHAM6.3-HAM2.2. The model has been run by the Department of Physics at Oxford, UK and the Institut für Meterologie at the University of Leipzig, Germany. Documentation of the ECHAM-HAM model can be found in https://doi.org/10.1002/jame.20015 and https://acp.copernicus.org/articles/12/8911/2012/. ECHAM-HAM delivered data on the base experiment, for the core experiments CO2x2 (doubling of CO2), BCx10 (tenfold BC) and Sulx5 (quintupling of Sulphate), and the phase 2 experiments CFC12 (from present day mixing ratio to 5ppb CFC12), CFC11 (from present day mixing ratio to 5ppb CFC11), N2O1p (from present day mixing ratio to 1ppm) and BCSLT (as BCx10, but with reduced atmospheric lifetime of BC). For this model there are three different versions of the core experiments base, base2 and base4. Base is the control run for the core experiments, base4 is for the BCSLT experiment, and base2 is the control run for the rest of the experiments.
