臺灣與離島地區的空氣品質除了受到季節性境外移入的中國沙 塵暴與霾害影響外， 本土污染物的排放也是重要的來源， 而各個地 區的空氣品質與主要污染物， 受生活型態差異、地理因素及天氣型 態影響， 有不同的時間及空間變化特性， 因此客觀預報技術的發展 便更顯重要。本計畫的工作目標在於結合數值動力模式預報與統計 方法， 發展空品區及縣市的客觀空氣品質AQI 預報指引， 為日後提 供鄉鎮尺度預報產品的重要基礎。本期工作重點有三， 首先進行現 有客觀預報指引產品的擴充， 包含維運現有統計模式MOS 及發展預 報校正產品DCA 及DMOS； 其二為利用氣象局高速運算電腦計算資 源，作業化運轉及維護環保署現有CMAQ-OP1.0 模式， 同時評估未來 模式升級之可行性； 最後則是維運及擴充空氣品質預報編輯及校驗 系統， 除持續精進空氣品質預報編輯及校驗系統外， 也介接不同工 作團隊的預報產品， 提供空氣品質預報圖像化產品。

In addition to the seasonal transboundary pollution included sandstorm and haze from China, the air quality of Taiwan and Taiwan’s offshore islands are also affected by the local pollutants. Caused by different lifestyle, geographical factors and weather condition, the time and spatial variability of air quality are quite different from space to space. Therefore, the 2 objective forecast technology development is significant for the air quality forecast. The major goal of this project is to develop objective air quality forecast guideline. The objective air quality forecast guideline combines with numerical dynamic model forecast and statistics forecast method which is an important basis for air quality forecast of villages and towns’ scale. There are three key aspects in this work. First, the expansion for current objective forecast guide products, including maintenance of existing statistic model DMOS and the development of statistic post-processing model DCA and DMOS. Second, operation and maintenance of EPA CMAQ-OP1.0 model on high-performance computing system in CWB and upgrade feasibility assessment for CMAQ-OP1.0 is also included. Last is the maintenance and expansion for forecast editor system and forecast calibration system. Besides improving the forecast editor system and forecast calibration system, the graphic air quality forecast products have been provided including the forecast products from other work teams.
