Welcome to the Satellite and Models databases web site of the AMMA project


The AMMA project includes in situ measurements at many locations of West Africa and in the Gulf of Guinea, an intensive use of satellite data and diverse modelling studies. Therefore, the AMMA database aims at storing a great amount and a large variety of data, and at providing the data as rapidly and safely as possible to the AMMA research community. In order to stimulate the exchange of information and collaboration between researchers from different disciplines or using different tools, the database provides a detailed description of the products and uses standardized formats. The database is now developed jointly at MEDIAS-France in Toulouse (for in situ measurements database and AMMA user interface) and at IPSL in Paris (AMMA-SAT for satellite database and AMMA-MOD for model database, avalaible on this site), and will be mirrored in Africa as early as 2008.

At this time, you can access in-situ measurements as well satellite data from AMMA-SAT via the AMMA user interface (http://amma-international.org/database/) but not yet the model outputs, only available on this web site.

African Monsoon Multidisciplinary Analyses (AMMA)

AMMA is a coordinated international project to improve our knowledge and understanding of the West African monsoon (WAM) and its variability with an emphasis on daily-to-interannual timescales.

AMMA overarching aims are:

  • To improve our understanding of the West African Monsoon and its influence on the physical, chemical and biological environment regionally and globally.
  • To provide the underpinning science that relates climate variability to issues of health, water resources and food security and defining the relevant monitoring strategies.
  • To ensure that the multidisciplinary research carried out in AMMA is effectively integrated with prediction and decision making activity.

It is AMMA's aim to provide the African decision makers with improved assessments of similar rainfall changes which are likely to occur during the 21st century due to natural fluctuations and as a result of anticipated global climate change. An essential step in that direction is to improve our ability to forecast the weather and climate in the West African region.

Based on a French initiative, AMMA was built by an international scientific group and is currently funded by a large number of agencies, especially from France, UK, US and Africa. It has been the beneficiary of a major financial contribution from the European Community's Sixth Framework Research Program. Detailed information on scientific coordination and funding is available on the AMMA International web site http://www.amma-international.org/.

At this time scientists from more than 25 countries, representing more than 140 institutes are involved in AMMA. An international structure has been established to oversee and coordinate the ongoing activities, the basic research and a multi-year field campaign. AMMA is developing close partnerships between those involved in basic research of the West African Monsoon, operational forecasting and decision making, and it is establishing blended training and education activities for African technical institutions and schools.

In addition to this international structure which has been set up, a network of African scientists linked to AMMA has been established which will help to consolidate existing collaborations in Africa and to federate initiatives through a pan-African partnership.

AMMA is endorsed by the World Climate Research Program (WCRP) and continues to develop in association with CLIVAR and GEWEX. AMMA has also been endorsed by IGAC and ILEAPS within International Geosphere-Biosphere Program (IGBP). AMMA is also working with THORPEX to achieve shared goals concerned with the prediction and predictability of meteorological and climate events which affect African societies. AMMA is working other international projects and programs of WMO to achieve its aims including GCOS and GOOS.
