Air Quality Consulting
The Air Quality Department specializes in analyzing odor events and locating sources of air and odor pollution, professional consulting services in the field of air quality, writing and verifying environmental impact surveys.
Detection of odor sources / air pollution and analysis of odor events
Odor nuisances occur in many areas of the country due to industrial, agricultural or pirate activity and they have a great impact on the quality of life of the city and country residents. Local and government authorities receive a large number of complaints about bad odors suffered by residents. In most cases the authorities do not have the means to determine what or where the source of the odor is, or to prove that a suspicious source is indeed to blame, in order to take preventive action, and thereby provide a solution to those residents affected by the odor nuisance.
Meteo-Tech’s Air Quality Department specializes in analyzing odor events and locating odor sources and air pollution. Meteo-Tech performs these analysis, and the detection of odor sources, using a unique, patent-protected model, which was developed by Meteo-Tech, and is based on meteorological data measured from an unlimited number of meteorological stations, which allows a complete and reliable answer, without need for air samples or field trips. The model has been tested many times and has shown great accuracy in locating odor sources. Also, using the model, it is also possible to test whether a potential odor source is what causes the odor nuisances. The system is accepted and used by the Ministry of Environmental Protection.
Using the model enables real-time results, using an online system that works from any computer, tablet or smartphone with Internet access. A retrospective event analysis can also be performed, based on historical meteorological data.
The meteorological analysis is based on backward and forward integration in time. In order to locate a potential source that emitted the odor, a backward integration in time is performed from the complaint site and in order to confirm the source, a forward integration in time is performed from the source in order to check where the emission from it spreads. Meteo-Tech has been providing its services in the field of detecting sources of odor / air pollution and analyzing complaints and odor incidents to the Ministry of Environmental Protection, industrial zones, local councils and municipalities for over 20 years.
Assessment of air pollution levels using models for pollutant dispersion
The Air Quality Department has extensive experience in calculating atmospheric pollutant dispersion and assessing local-scale air pollution levels. The department uses a number of advanced and regulatory models for calculating pollutant concentrations in the atmosphere and particle subsidence. These models (such as AERMOD, CALPUFF and CALROAD) are approved by the EPA, EEA and the Ministry of Environmental Protection.
Using these models it is possible to perform calculations of air pollutant concentrations resulting from industrial, transportation and other sources, to estimate the levels of potential concentrations expected to be emitted as a result of various activities and to use the results of the calculations for licensing, planning or testing purposes.
Our special projects:
Some special projects include unique and complex research and consulting work that reflects the diverse ability of Meteo-Tech to combine the field of meteorology with the field of air quality and the environment. Among the projects are the following works:
- A project on behalf of the Ministry of Environmental Protection "National Reduction Targets for Air Pollution in Israel".
- A project for "air resource management in Israel" on behalf of the Ministry of Environmental Protection.
- Inventories of dioxin and purine emissions in Israel for 2005.
- Estimates of air pollution emissions from aircraft and cruises in Israel.
- Emissions of air pollution from trains in Israel.
- A guide to treating odor hazards.
The department has an extensive archive of meteorological data and observations. The archive includes more detailed data from dozens of meteorological stations in Israel and thousands of stations in the Middle East. The data are of the highest resolution and have undergone comprehensive quality tests
