SDS-WAS and ICAP multi-model products routinely plotted side by side
The Sand and Dust Storm Warning Advisory and Assessment System (SDS-WAS) is a World Meteorological Organization's project aimed at enhancing the capacity of countries to deliver timely and quality sand and dust forecasts to end-users. The SDS-WAS Regional Center for Northern Africa, Middle East and Europe daily computes multi-model products from the following set of models: BSC-DREAM8b, MACC, DREAM8-NMME-MACC,NMMB/BSC-Dust, MetUM, NASA GEOS-5, NCEP NGAC, EMA RegCM4 and DREAMABOL.
The International Cooperative for Aerosol Prediction (ICAP) is an international forum for aerosol forecast centers, remote sensing data providers, and lead systems developers to share best practices and discuss pressing issues facing the operational aerosol community. The ICAP computes its own dust multi-model ensemble for a global domain (Sessions et al., 2014). It is built from the following systems: ECMWF MACC, JMA MASINGAR, NASA GSFC/GMAO, FNMOC/NRL NAAPS, NOAA NGAC, Barcelona Supercomputing Centre NMMB/BSC-CTM and Met Office Unified Model.
This SDS-WAS Regional Center for Northern Africa, Middle East and Europe daily plots side-by-side the mean and the standard deviation of dust optical depth yield by both multi-model systems for their common domain. The product is published with a 2-day lattency. Plots since 1 April 2015 are available at
