The historical emissions simulation contained in this dataset includes time varying (1949-1989) forcing from major and minor greenhouse gases, anthropogenic sulphur cycle with direct plus indirect sulphate aerosol effects, and variations in tropospheric ozone based partly on off-line chemistry calculations. It forms part of the second QUMP (Quantifying Uncertainty in Model Predictions) fully coupled transient ensemble. A previous simulation covered the period 1859-1949 (HadCM3-HIST1-QUMP).

The simulation data contained in this dataset is part of the 2nd QUMP (Quantifying Uncertainty in Model Predictions) Fully Coupled Transient Ensemble. It uses boundary conditions representing historical emissions covering the latter part of the 20th century. This run is part of a 17 element historical emissions ensemble produced by the Hadley Centre QUMP project. The HadCM3 model was used by the Hadley Centre to provide input for the IPCC Third Assessment Report.

Data members run for this experiment: aenwh

Boundary conditions: HadCM3 all-anthropogenic forcings experiment with multiple species of greenhouse gases including various minor species); sulphate aerosol direct and indirect forcing; sulfur chemistry with natural DMS and 3D SO2 background emissions, and tropospheric/stratospheric ozone.

Initial conditions: The model is initialised directly from the previous QUMP historical emissions simulation covering the period 1859-1949 (run: aenwg date: 1949-12-01).

More detailed metadata on the model configuration and parameters is available in XML format.
