The experiment aims to investigate how the representation of convection influences the West African Monsoon during the mid-Holocene.
Atmospheric and SST input data originate from the MPI-ESM Holocene simulations reflecting Holocene condition.
External Parameters (surface condition) reflect present-day conditions similar to the experimental setup of PMIP1: The Sahara remains a desert.
We use the ICON (ICOsahedral Nonhydrostatic) model framework version 2.5.0 (see Zängl et al. (2014) for more details).
The provided data covers one simulation from June to October (JJASO) for the year 7023 before present (BP) with the year 2000 as the reference year.
The time axes of the NetCDF files reflect the model year which is based on the time axes of the MPI-ESM slo0021a Holocene simulations. The artificial model year 1001 in slo0021a refers to the year 8000 BP. Therefore, the model year 1977 refers to the year 7023 BP.
The experiment compares a 5km horizontal resolution, cloud-resolving simulation with a 40km-horizontal resolution, parameterized convection simulation.
The 40km-domain (DOM01) covers a range from 70.5°W - 99.5°E; 49°S - 59°N
The 5km-domain (DOM04) covers a range from 37°W - 53°E; 0°N - 40°N
The dataset provides daily mean values on the triangular ICON grid.
The datasets provide atmospheric (3D), surface (2D) and precipitation (2D) data an the following variables:
rain_con_rate, rain_gsp_rate, clct, geopot, temp, rh, qv, u, v, w, w_so, runoff_g, runoff_s, lhfl_s, shfl_s, soiltyp
