Abstract
There is evidence that the land surface influences the variability of the West African Monsoon (WAM) over a wide range of spatio-temporal scales. A high priority goal of the AMMA project is to better understand and model the influence of the spatio-temporal variability of surface processes on the atmospheric circulation patterns and the regional water cycle related to the West African Monsoon. This issue is being addressed under the auspices of the AMMA Land surface Model Inter-comparison Project (ALMIP). An ensemble of state-of-the-art land surface models have been forced with the best quality and highest (space and time) resolution data available in order to better understand the key processes and their corresponding scales.
In the first and primary part of this talk, a summary of the first phase of ALMIP (at the regional scale for several annual cycles) is given. An overview of the experimental design and different forcing (input) datasets is presented, followed by a summary of the main model inter-comparison results for several annual cycles focusing over West Africa. Next, a summary of various uses of the resulting model simulated fields is given, consisting in coupled land-atmosphere model initiation and evaluation (since regional scale estimates of surface fluxes and deep soil moisture since 2002 currently do not exist). Finally, various evaluation efforts are highlighted.
In the second part of this talk, perspectives for ALMIP Phase 2 will be given. The main goal of ALMIP-2 is to examine the ability of the land surface models to capture key processes related to near surface hydrology, sub-surface transfers of energy and water, surface atmosphere transfers and vegetation. This phase of ALMIP will focus on the mesoscale to local scales using data from the dense observational networks set up during the AMMA field campaign. An overview of candidate sites and datasets will be given, and the main scientific goals will be presented.
