The Technion Center of Excellence in Exposure Science and Environmental Health
Past Projects
The last decade has shown a considerable progress in satellite remote sensing (SRS) of dust particles. From an environmental health perspective, such an event detection, after linking it to ground PM concentrations, can proxy acute exposure to respirable particles of certain properties (i.e. size, composition, toxicity).

A portable hyperspectral camera system that operates in the visible-NIR spectral range was used to develop a ground hyperspectral imaging methodology for spatiotemporal monitoring of fine PM concentrations along urban-scale open paths (line segments) during the night.

Concentrations of particulate emissions from a quarries/open pit mines located in hilly terrain, estimated by atmospheric dispersion models, were hardly ever evaluated.
More...
developing advanced statistical methods to assess ground PM levels based on satellite AOT observations and studying the feasibility to use MODIS products of higher spatial resolution (MAIAC) over the currently used coarse resolution products (DT and DB algorithms)

For a given emissions inventory, the general levels of air pollutants and the spatial distribution of their concentrations are determined by the physicochemical state of the atmosphere.
