What Is New About This Web Site
For the first time, students have direct access to the database of air monitoring information gathered from EPA’s Melbourne and Geelong Air Monitoring stations.
Since 1998, information about current air quality has been available on EPA’s web site, but with this new facility, students can access historical data and build up pictures of how air pollution varies with time.
For example, a student can select to view the concentration of particles for a 24-hour period in the middle of winter and see how the concentration of air borne particles starts to build up about 6pm (as people light their fires for home heating) and build up to a peak close to midnight. If the concentration of particles in winter time is low, they can check the temperature and wind conditions to see why the readings might be low.
Selecting a 24-hour period for particles in summer time will show much more modest readings for air particles, except when unusual occurrences such as the King Island fires, with the right wind conditions, were responsible for smoke blowing across Melbourne.
Being able to see how different pollutants vary at different times of the year, and different times of the day, can be important factors in working out how best to control such pollutants.
