The SDS-WAS programme at WMO

SDS-WAS was established in 2007 in response to the intention of 40 WMO member countries to improve capabilities for more reliable sand and dust storm forecasts. Research forecasting products from atmospheric dust models may substantially contribute to risk reduction in many areas of societal benefit. It will rely on real-time delivery of products.

More than 15 organizations currently provide daily dust forecasts in different geographic regions. The SDS-WAS integrates research and user communities (e.g. medical, aeronautical, agricultural users). SDS-WAS is established as a federation of partners organized around regional nodes. At the moment two nodes are established: the Northern Africa-Middle East-Europe Node (hosted by Spain) and the Asian Node (hosted by China). The SDS-WAS mission is to achieve comprehensive, coordinated and sustained observations and modeling capabilities of sand and dust storms in order to improve the monitoring of sand and dust storms to increase the understanding of the dust processes and to enhance dust prediction capabilities.

Objectives of the SDS-WAS

SDS-WAS Science and Implementation Plan 2015-2020

  • To enhance operational SDS forecasts through technology transfer from research.
  • To improve observation technology
  • To provide users access to forecasts and observations
  • To promote research and applications related to the sand and dust storm process
  • To build capacity of countries to utilize SDS products
  • To build bridges with other relevant communities
