Climate Simulation with CLM, Scenario A1B run no.2, Data Stream 2: European region MPI-M/MaD


Keuler, Klaus et al.

The experiment CLM_A1B_2_D2 contains European regional climate simulations of the years 2001-2100 on a rotated grid (CLM non hydrostatic, 0.165 deg. hor. resolution, see ). It is forced by the second (_2_) run of the global IPCC scenario A1B (EH5-T63L31_OM-GR1.5L40_A1B_2_6H), which describes a possible future world of very rapid economic growth, global population peaking in mid-century and rapid introduction of new and more efficient technologies with a balance across all energy sources.
In data stream 2 (_D2) the output variables of CLM are stored as time series on a rotated grid. The model region starts at -20.8725/-23.7275 (lat/lon in rotated coordinates; centre of lower left grid box) with rotated North Pole at 39.25/-162.0 (lat/lon). The number of grid points is 255/241 (lat/lon). The sponge zone (numerically unreliable boundary grid points) of the original model output has been cut off.
The regional model variables include two-dimensional near surface fields, as well as soil and atmospheric fields on different layers. The soil fields are simulated on 10 different levels with a maximum depth of 15 meters. The atmospheric fields are given on 6 pressure levels (200, 500, 700, 850, 925 and 1000 hPa). The time interval of the output fields ranges from 1 to 3 hours and includes daily output fields, depending on the respective variables.
