Central Asian DUst Conference (CADUC)

8–12 April 2019, Dushanbe, Tajikistan

Preface

The Central Asian DUst Conference gains more insight into the different aspects of Asian dust: its properties, its sources, its transport mechanisms and processes, its effects on humans and economies, and finally on its sinks. The conference brings together scientists in Central Asia. Worldwide, the conference creates a better presence of the issue of Asian dust in Central Asia. The conference contributes to the cooperation of different countries regarding the Asian dust. Last but not least the conference supports capacity building, especially in contributing to the education of young scientists regarding the Asian dust in Central Asia.

Sessions:

Dust at sources
Dust at transport
Dust at sinks
Impacts of dust

Conclusions

Notes on Possible CADUC Follow‐On Activities
(Some results from the CAUDC discussions, Dushanbe, April 2019)

Possible Advances in Research

• Better integration of satellite data to provide context for site‐specific observations (can also help in selecting sites for future in situ observation)
• Dust source region mobilization & emission flux long‐term measurements, including wind gusts and extreme events (camera + OPC + anemometer)
• Dust particle optical properties (extinction, absorption, scattering phase function) – especially coarse dust and different dust types
• Particle composition measurements, including salt and bio‐aerosol components
• Dust particle property evolution during transport & at surface in source regions (including transport over pollution sources)
• Specific Source and Receptor profiles and in situ dust samples (aircraft + surface)
• In situ sampling of dust on glaciers to assess effects & help validate satellite observations
• Long‐term monitoring at surface stations to capture seasonal & inter‐annual variability
• Apply height‐resolved radiative forcing measurements to better constrain model simulations of aerosol (especially BC) radiative effects

Scientific Contributions offering Possible Direct Societal Benefit

• Source Identification and impacted regions
  • We can locate the specific, major source regions
  • We can identify transport pathways and likely deposition regions
• Source Characterization
  • Particle types: composition, fluxes, seasonal source behavior
  • Ambient water resources and water cycle
  • Vegetative environment, what exists, what might grow best
  • Projections of future change in source extent and properties
• Possible Mitigation Options (effectiveness, feasibility, sustainability, costs)
  • Planting (+ agricultural practices) in the region
  • Constructing wind breaks
  • Land and water management practices
  • Warning systems
• Scientific Report
  • Dispassionately present the scientific results
  • Present options, but avoid specific policy recommendations
