The Sand and Dust Storm Warning Advisory and Assessment System (SDS-WAS) is an international scientific coordination initiative established in 2007 under the Global Atmosphere Watch (GAW) programme. Its primary objective is to develop a global network for sand and dust storm (SDS) research and operational forecasting, thereby advancing the science underpinning the United Nations Coalition for Combating Sand and Dust Storms.

By facilitating technology transfer and collaboration across a coordinated network, SDS-WAS enhances the capacity of WMO Members to deliver timely and accurate SDS forecasts and early warnings. This initiative strengthens global preparedness and mitigates the impacts of SDS on ecosystems, health, and socio-economic activities.

Since May 2017, China Meteorological Administration (CMA) has designed and served as the Regional Specialized Meteorological Centre for Atmospheric Sand and Dust Forecasting (RSMC-ASDF Beijing) under WMO Integrated Processing and Prediction System (WIPPS). In compliance with WMO regulations (WMO-No.485), the centre delivers critical services for the Asian region, including SDS numerical forecasts, observational data dissemination, model verification, as well as technical exchanges and capacity-building activities.

Aligned with the WMO Strategic Plan (2024–2027)—which prioritizes early warning systems, climate resilience, and cross-border collaboration—the 11th SDS-WAS Asia Regional Steering Committee Meeting and International Workshop on Sandstorm Early Warning will strengthen RSMC-ASDF Beijing’s role in operational guidance and foster global cooperation. By facilitating the exchange of cutting-edge research, operational best practices, and regional SDS monitoring technologies, this event directly supports WMO’s goal of "Early Warnings for All" and enhances collective preparedness for SDS impacts across Asia and beyond.
