– to investigate the spatial extent of the effects caused by downwind deposition of dust emitted from the new desert regions; to measure chemical and physical properties and to assess the effect of dust on local meteorological conditions, climate and ecology (the project will incorporate the study of the nature of dust produced from new desert regions and mechanisms of dust product ion, composition, transport, and deposition);
– to investigate the chemical composition of the aerosols and soil, the shape and size distribution of particles, spectral course of the complex refractive index, spectral transparency for the solar and thermal radiation, meteorological conditions pressure, temperature, wind, humidity, visibility, their connection with the atmospheric turbidity and with conditions of forming dust outbreaks;
– to develop numerical models for dust and salt transfer in new desert regions with reference to concrete regions, topography being taken into account.
Exected results: to develop a numerical model capable of predicting dust fluxes for remote and poorly mapped areas of desert regions; to develop methodologies to assess salt and dust deposition on agricultural areas; to estimate the effect of dust on meteorology, climate and ecology; to develop recommendations for suppressing the processes of dust and salt transfer.
Scientific and economic significance: understanding of the mechanisms of desertification for agricultural areas, the role of lake desiccation in the global dust budget and the role of dust and salt In change of the local radiation balance.
The International Science and Technology Center (ISTC) is an intergovernmental organization connecting scientists from Kazakhstan, Armenia, Tajikistan, Kyrgyzstan, and Georgia with their peers and research organizations in the EU, Japan, Republic of Korea, Norway and the United States.
ISTC facilitates international science projects and assists the global scientific and business community to source and engage with CIS and Georgian institutes that develop or possess an excellence of scientific know-how.
