	DEMONSTRATION OZONE CALCULATOR

The purpose of the ozone calculator is to provide community members some information about how ozone forecasts are made, and also some insight into how weather conditions and can affect ozone air quality.   You can input values for the next day's weather forecast to get an approximate ozone forecast.  Also, you can tinker with the calculator to see the effects of changing the weather conditions.

The University of Louisville ozone models are statistical models based on relationships between meteorology and ozone concentration.  The models use several meteorological parameters as input.  Some of these parameters, such as "atmospheric transmittance"  are abstract quantities derived from complex equations.  Some other information, such as hourly wind speed, dew point temperature, etc. can be obtained from the output of numerical weather forecast models.   The automated forecast models obtain the numerical weather forecast model output from regularly updated websites.   Ozone forecasters have access to a wide range of meteorological forecast information.  Ozone forecasters sometimes adjust the model output based on subjective judgments about regional transport of pollutants and synoptic weather conditions.   The demonstration ozone calculator uses basic weather forecast information (e.g. daily maximum temperature, daily maximum temperature, sky conditions, etc.) for making ozone forecasts.
