Classification of dust days over Israel by integration of satellite remote sensing products

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).

Remote sensing of airborne particulate matter near the ground by nighttime hyperspectral imaging

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.

Development of methodology for risk assessment as a result of large scale area development and open pit phosphate mining

Concentrations of particulate emissions from a quarries/open pit mines located in hilly terrain, estimated by atmospheric dispersion models, were hardly ever evaluated.

Integration of satellite-borne observations and ground monitoring and its application for assessing exposure to PM in Israel

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)

Exploring the applicability of future air quality predictions based on synoptic system forecasts

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.
