IIBR's multi-faceted air pollution research includes numerous aspects of meteorological
modeling and measurement, pollutant sampling, and risk assessment. The Institute
employs and develops calculational tools for the prediction of flow regimes and
pollution concentrations on various scales, from the indoor environment, through
urban areas, up to large, complex terrains. Among these tools are advanced models
for atmospheric winds and meteorological profiles (WRF, MM5, as well as IIBR-developed
models), dispersion models for simulating the concentration field (CALPUFF and Lagrangian
techniques), statistical models for small- and meso-scale wind prediction, and fluid
dynamic models for indoor flow calculations (FLUENT, CONTAM).
IIBR's environmental and occupational safety testing is performed by state-of-the
art equipment and qualified personnel certified by the USEPA and also authorized
by the Israel Ministry of Labor. The versatile, integrated meteorological array
includes a tethered balloon system capable of simultaneously measuring wind, temperature,
and humidity at a high sampling frequency at various heights. In addition, IIBR's
meteorological system is comprised of equipment and proven techniques for measuring
extremely low wind speeds near surfaces, necessary, for example, in indoor environmental
measurements.
Incorporating its vast experience in working with atmospheric tracers, both gaseous
and particulate, IIBR conducts field tests, both indoors and outdoors, of atmospheric
pollutant transport models, relying on the Institute's in-house sampling and analysis
capabilities.
On the basis of their expertise in these fields, IIBR researchers also perform assessments
of environmental risk in various scenarios, such as those resulting from possible
malfunctions in industrial processes involving hazardous materials, including their
production, transport, and storage. These analyses employ the accepted PRA (Probabilistic
Risk Analysis) approach, HAZOP (Hazard Operability Studies) and HAZAN (Hazard Analysis)
techniques, linked with various models to assess the potential environmental consequences.
