The Environmental Protection Agency (EPA) of the Executive Yuan has carried out the air quality forecasting work for the next 3 days in 7 air areas and 3 outlying islands (Penghu, Matsu and Kinmen) since 2010. Since 2018, EPA has uploaded the air quality forecasts to the EPA website, “Environment Info Push” APP and “i-Environment” website every 10:30 AM, 4:30 PM and 10:00 PM. People can download and checkout the forecast anytime. In addition, pictures and press will be released to remind relevant units and the public to pay more attention on this issue during the time of poor–quality air each year. Nowadays, the air quality forecasting products depend on forecasters analysis. Forecasters need to analyze lots of observation and forecasting data so that they can determine the content of air quality forecasts. With the technology and data forecasting models progress, EPA would like to strengthen the forecast editing systems. This project provides kinds of statistical methods which can transform the result into the initial value of official forecasts by interfacing multi–model system. The forecasters can just find–tune the calculation results. This will make them take less time to edit the official forecasts. It’s really a good way to increase the efficiency of forecasts editing and the possibility of developing more elaborative forecasts in the future.
