Summary | The data set comprises the output from a coupled ocean atmosphere model experiment. The model was run for 75 years with 1 x carbon dioxide in the control run and a compound increase in carbon dioxide of 1% per year in the transient run. 2 x carbon dioxide reached at 70 years. The atmosphere model is on a 2.5 x 3.75 degree latitude/longitude grid and has 11 vertical levels as follows: 100m, 600m, 1.5km, 3km, 4.5km, 7km, 9km, 10.5km, 13km, 17km, 25km. The ocean model is on a 2.5 x 3.75 degree latitude/longitude grid and has 17 vertical levels as follows: 5.0m, 15.0m, 25.0m, 35.1m, 47.4m, 66.5m, 95.8m, 138.9m, 203.7m, 301.0m, 447.1m, 665.3m, 995.6m, 1490.0m, 2232.3m, 3295.9m, 4707.0m. Stored variables for atmospheric data - daily fields for years 66-75, monthly fields for years 1-65: mean sea level pressure, x and y components of wind at 850mb, 500mb and 250mb, temperature at 850mb and 500mb, 500mb height, surface pressure, x and y components of wind, temperature, specific humidity, surface sensible heat flux, evaporation from surface, convective rainfall, snowfall, large-scale rainfall, snow depth, soil moisture content, 00Z surface temperature, minimum, maximum and mean surface temperature, lowest model layer wind speed, wind mixing energy, mean temperature at lowest model level, sublimation, snow melt, run-off. Monthly-mean fields for years 1-65 in addition to those above: boundary layer height, surface geopotential height, mean temperature at lowest sigma level, CD (drag coefficient), CH (bulk heat transfer coefficient), x and y components of stress, soil temperature in layers 2, 3 and 4, incoming/outgoing solar flux, outgoing infrared flux, surface solar flux (up and down), surface infrared flux (up and down), cloud amount in model layers, convective cloud base and top (weighted), convective cloud amount, total cloud amount, sub-gridscale orography variance, ocean: x and y components of wind stress, net surface heat flux, net solar radiation, precipitation-evaporation.
