Joint visualization. Dust AOD at 550 nm
RUN: 21 Oct 2012 VALID: 21 Oct 2012 12:00 – 24 Oct 2012 00:00
Joint visualization. Surface concentration
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

nrt evaluation using AERONET data
• Monthly• Seasonal• Annual
Besides dust, there might be other aerosol types. Therefore, negative BE could be expected.
• Bias Error• Root Mean Square Error• Correlation Coefficient• Fractional Gross Error

Capacity building
19-23 Nov 2012: Cours sur l’utilisation des produits satellitaires aux applications agrometeorologiques, Niamey, Niger
26-28 Nov 2012: Workshop on Meteorology, Sand and Dust Storm (SDS), Combating Desertification and Erosion. Ankara, Turkey
Important meetings
Sep 2012. The WMO CBS-15 meeting recommends the designation of the Center as Regional Specialized Meteorological Center with Specialization on Atmospheric Sand and Dust Forecast(RSMC-ASDF).
Jul 2013. It is expected that the WMO Executive Council meets the recommendation and the RSMC starts working.
9-15 Sep 2012: WMO Fifteenth Session of the Commission for Basic Systems (CBS-15), Jakarta, Indonesia
20-22 Nov 2012: Regional Conference on Dust and Dust Storm, Kuwait
UNEP and WMO organized a special session on the scientific aspects of the Regional SDS Programme. Experts gave recommendations on the programme improvement.
Plans for 2013: Outstanding activities
• Dissemination of numerical forecast products (Mar 2013)• Publication of an activity report (Jun 2013)• Start of activities in the Operational Center
(Sep 2013)• Preparation of a scientific conference on
dust to be held in Barcelona in spring 2014 (together with a face RSG meeting)• Participation in capacity building activities
(Turkey, Oman)• Joint evaluation of the dust models: new
approaches
