Abstract

|
|
The study has analyzed impacts and intensity of weather that affect PM₁? concentration based on PM₁? forecast conducted by the city of Seoul in order to identify ways to improve the accuracy of PM₁? forecast. Variables that influence PM₁? concentration include not only velocity and direction of the wind and rainfalls, but also those including secondary particulate matter, which were identified to greatly influence the concentration in complicated manner as well. In addition, same variables were found to have different impacts depending on seasons and conditions of other variables.
The study found out that improving accuracy of PM₁? concentration forecast face some limits as it is greatly influenced by the weather. As an estimation, this study assumed that basic research units and artificially estimated pollutant emissions, study on mechanisms of secondary particulate matter productions, observatory compliment, and enhanced forecaster"s expertise are needed for better forecast.
