Parameterisation of convective PBL using surface data for the wind and stability classes
A simple two-layer model of convective planetary boundary layer (CPBL), consisting of a Surface Layer and an Ekman layer over it and developed in accordance with the similarity theory is used to obtain the vertical profiles of the temperature, wind velocity and the turbulent exchange coefficient in CPBL from the surface wind measurements and atmospheric stability data. As input to this model the ...

A Lagrangian dispersion model with chemical reactions
A Lagrangian stochastic (single particle) model is modified in order to account for simple chemistry reactions and tested against measured wind tunnel data. These data refers to a reactive plume generated by a single point source of NO inside a turbulent grid flow doped with ozone. The comparisons were made at different distances from the emission considering all the substances involved in the ...

Airport Monitoring at Riyadh Airport - Case Study
Riyadh King Khalid International Airport faces heavy pollution due to frequent dust storms and airplane emissions. Oizom helped in monitoring the air quality of the airport by installing Polludrone. Polludrone acquired the pollution data and analyzed the historical data and trends. With this solution, the airport authorities were able to identify the source and generate alerts in cases of high ...

Site Vulnerability Assessments for Facilities That Use, Store, or Transport Chemicals
In response to pressing issues facing the new Department of Homeland Security, over 15,000 chemical and industrial plants may have to evaluate their vulnerability to terrorist attack and improve countermeasures at their facilities. Federal lawmakers are considering two bills requiring facilities to submit site security plans: the Chemical Security Act (Senate Bill S. 157, reintroduced in January, ...

Managing dust risks at quarries
In the following article, Josh Thomas from instrumentation specialist Ashtead Technology, discusses the risks associated with dust at quarries, and highlights the vital role of monitoring. Background Almost all quarrying operations have the potential to create dust. Control measures should therefore be established to prevent the generation of levels that cause harm. These measures should be ...
