A large portion of atmospheric particulate matter is produced in arid regions of the Earth and transported around the globe. The impact of mineral dust on meteorology, air quality, climate, health and ecosystems represents a major scientific and societal issue. The World Meteorological Organization (WMO) Scientific Steering Committee meeting for Sand and Dust Storm (SDS) Project (November 2006 Shanghai, China) approved the establishment of a WMO-coordinated global network of SDS forecasting Centers delivering products useful to a wide range of users for reducing the impacts of SDS. For Europe, Africa and Middle East, Spain is currently implementing a WMO Regional SDS WS Centre. A consortium of three research institutions composes the Regional Centre: the Barcelona Supercomputing Center (BSC), the Spanish National Institute of Meteorology (INM) and the Earth Sciences Institute ‘Jaume Almera’ (IJA-CSIC).

This Regional Centre aims to achieve three major objectives: 1) provide real-time information from a core-operational and quality controlled dust monitoring and forecasting system; 2) maintain a web portal with both research and near-real information and links to available dust forecasting and monitoring systems within the region; and 3) implement a web-oriented modelling and observational historical data base available for case-study and climatological analysis.
Real time dust monitoring and forecasting is now the main duty of the Regional SDS WS Center. The initial state of the system is based on the Dust Regional Atmospheric Model (DREAM) which provides daily 50x50 km2 dust forecasts for Europe, North Africa and Middle East (http://www.bsc.es/projects/earthscience/DREAM/). Quantitative verification studies performed so far, using data from observation networks such as the European EARLINET (lidars; http://www.earlinet.org/) and the international AERONET/PHOTONS (sun photometers; hhtp://aeronet.gsfc.nasa.gov), satellite and ground level PM levels have outlined the good skills of the model concerning both the horizontal and vertical extent of the dust plume in the geographic region of application. Near-real time monitoring is performed using aerosol optical depth from AERONET/PHOTONS network, PM from on-line ground stations and 15-minute resolution and 3x3 km2 dust products derived from Seviri-MSG (Meteosat Second Generation). On going activities deal with both scientific and operational improvements. New user-driven dust products are being implemented with the final goal to set up a dust-“one stop shop” within the Region.
