The data represent 6 hours values of a simulation of an annual increase of 1%,starting in 1931, until CO2 quadrupling. In the year 2001 the CO2 concentration were held constant. The simulation is a continuation of the 1CO2_2-run and was run on a NEC-SX6 (hurrikan), the output from the model run is stored in : hurrikan.dkrz.de:/ut/k/k204098/EXP000/run017 Datasets with monthly mean values are also available.
