DustClim: Decadal DUST reanalysis, ready!

Sand and Dust Storms (SDS) are an important threat to life, health, property, environment and economy in many countries, play a significant role in different aspects of weather, climate and atmospheric chemistry. There is an increasing need for SDS accurate information and predictions to support early warning systems, and preparedness and mitigation plans. This is in alignment with the mission of the WMO Sand and Dust Storm Warning Advisory and Assessment System.

An advanced dust regional model reanalysis for Northern Africa, Middle East and Europe covering 10 years (2007-2016) based on the MONARCH atmospheric model is now ready. The novelties of the DustClim reanalysis include an unprecedented high-resolution (10 km x 10 km), the assimilation of satellite products over dust source regions with specific dust observational constraints, and a thorough evaluation (with a particular focus in the period 2011-2016, see Figure) using a wide variety of observations and data from experimental campaigns from ground-based and satellite products. This dust reanalysis is being used for the development of dust services specifically designed for air quality, aviation and solar energy.

There is currently a very limited integration of dust information into practice and policy. DustClim methods for assessing dust impacts in selected socio-economic sectors (i.e. air quality, solar energy and aviation) are used in the ongoing United Nations  Asian and Pacific Centre for the Development of Disaster Information Management (ESCAP/APDIM) risk assessment report for Asia-Pacific.
