Impacts of Sand and Dust Human Health (Asthma, infections, Meningitis in Africa, Valley Fever in the America’s) Agriculture (negative & positive impacts) Marine productivity (negative & positive impacts) Improved Weather and Seasonal Climate prediction Aviation (air disasters) Ground Transportation (high speed rail) Industry (Semi-conductor, etc.) Energy (Thermal solar energy)
SDS-WAS Mission To enhance the ability of countries to deliver timely and quality sand and dust storm forecasts, observations, information and knowledge to usersthrough an international partnership in research and operations
SDS-WAS research issues • Sources • physical, optical and chemical properties • interaction with radiation, clouds and precipitation • Model validation and intercomparison • Ensemble forecasting • Impacts of dust (health, transport, agriculture) • Improve weather, climate and air quality modelling
History and Milestones in SDS-WAS • 2004: International Symposiumon SDS & a WMO Experts Workshop on SDS (CMA, Beijing-China). • 2005: a questionnaire on SDS to WMO Members indicated 40 interested countries. • 2006: Sand and Dust Storm Warning Advisory and Assessment System (SDS-WAS) proposed (CMA, Beijing-China). • 2007: the 14th WMO Congress endorsed the launching of the SDS-WAS • 2008: WMO SDS-WAS Implementation plan drafted (Athens, Greece). • 2010: First SDS-WAS hands-on training Workshop (BSC, Barcelona-Spain).

CollaborationMechanisms Flow of information between SDS-WAS system components for a regional node consisting of a consortium of partners supported by the Regional Steering Group and Regional Centre
A Pan-American Center for the WMO SDS-WAS • Information relevant to airborne dust (as it impacts socio‐economic and environmental sectors including health, safety, water supplies, air quality, agriculture, fisheries, commerce and defense) is at the Center’s core. • The Center facilitates research & applications for North, Central and South America. • The Pan‐Am Center acts as a node to Exchange information, talent, & infrastructure across the Americas to facilitate progress in predicting, adapting to, and avoiding maladies of airborne dust, crossing scales of weather and climate, región & globe. William A. Sprigg Chapman University (USA)
Future West Asia (Gulf Countries + Iran + Turkey) for the WMO SDS-WAS A support from the West Asian UNEP office • A short-term project to perform an assessment report on skills and needs for establishing a new WMO SDS-WAS node • A technical UNEP/WMO SDS conference was held in Abu Dhabi (May 2013) to discuss further steps
Current research topics in SDS-WAS Regional Centers Model validation/evaluation High resolution modelling Data assimilation Long term forecasting Improvement/characterization of dust observations Dust impacts
Themodels • VARIABLES: Dust surface concentration – Dust Optical Depth at 550 nm • LEAD TIME: 0 – 72 hours, every 3 hours • GEOGRAPHICAL DOMAIN: 25ºW – 60ºE, 0 – 65ºN
Generation of multimodelproducts Model outputs are bi-linearly interpolated to a common 0.5ºlon x 0.5ºlat grid mesh. Then, different multi-model products are generated: • CENTRALITY: median - mean • SPREAD: standard deviation – range of variation
