ICON-NWP simulations of the mid-Holocene West African Monsoon using parameterized an explicit convection and present-day land surface

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

Attribute description
air_temperature
Descriptor

Air temperature is the bulk temperature of the air, not the surface (skin) temperature. [CF-Standard Name]; unit: not filled

Attribute description
geopotential
Descriptor

Geopotential is the sum of the specific gravitational potential energy relative to the geoid and the specific centripetal potential energy.[CF-Standard Name]; unit: not filled

Attribute description
specific_humidity
Descriptor

"specific" means per unit mass. Specific humidity is the mass fraction of water vapor in (moist) air.[CF-Standard Name]; unit: not filled

Attribute description
pward_air_velocity
Descriptor

pward_air_velocity; unit: not filled

Attribute description
soil_type
Descriptor

A variable with the standard name of soil_type contains strings which indicate the character of the soil e.g. clay. These strings have not yet been standardised. Alternatively, the data variable may contain integers which can be translated to strings using flag_values and flag_meanings attributes.[CF-Standard Name]; unit: not filled

Attribute description
eastward_wind
Descriptor

"Eastward" indicates a vector component which is positive when directed eastward (negative westward). Wind is defined as a two-dimensional (horizontal) air velocity vector, with no vertical component. (Vertical motion in the atmosphere has the standard name upward_air_velocity.) [CF-Standard Name]; unit: not filled

Attribute description
northward_wind
Descriptor

"Northward" indicates a vector component which is positive when directed northward (negative southward). Wind is defined as a two-dimensional (horizontal) air velocity vector, with no vertical component. (Vertical motion in the atmosphere has the standard name upward_air_velocity.) [CF-Standard Name]; unit: not filled

Attribute description
upward_air_velocity
Descriptor

vertical wind velocity A velocity is a vector quantity. "Upward" indicates a vector component which is positive when directed upward (negative downward). Upward air velocity is the vertical component of the 3D air velocity vector. [CF-Standard Name]; unit: not filled
