Sensing the Microenvironment

摘要

You are an air quality sensor! As an air quality professional you will have developed a peculiar set of skills - a sensitivity to clean or polluted air - above and beyond the reach of mere 'normal' people. For some it is the calibrated expert nose. Others have a finely-tuned eye for haze. Some have an uncanny ability to estimate concentrations of invisible pollutants to the nearest ppb just by 'being there'. And the rest of us can often just look at or visit a site and just 'feel' the air quality.
