This Air Pollution Training Institute (APTI) course uses video presentations, text materials, and reading assignments to present basic meteorology, meteorological effects on air pollution, meteorological instrumentation, air quality modeling, and regulatory programs requiring a knowledge of meteorology. It consists of seven lessons that cover solar and terrestrial radiation, cyclones and anticyclones, wind speed and direction, atmospheric circulation, and many other topics. To finish the course, an online quiz is offered. Students may take the quiz for APTI Continuing Education Unit (CEU) credits; registration is required to receive CEU credits.
