本計畫目標為執行環保署微粒超級監測站(以下稱超測)儀器品質保證(品保)查核，以確認監測數據品質。各監測站每月與每季均需執行1次定期查核，本年度並進行原橋頭站搬遷成為崙背站的品保查核。在數據品質提昇方面，本計畫參與每月及每季超級測站維護作業與運轉檢討會議，自99年4月份起，每週並檢視維護單位彙整的儀器狀況週報表，提供審查意見給環保署。此外，本年度整合訂出一個適用於所有超測儀器的品保查核程序，以及訂出刪除錯誤和不合理數據的方法，使監測數據品質得以提昇。在各項儀器的資料可用率方面，共通性儀器以微粒質量濃度監測儀PM2.5的98.6%為最佳，微粒碳成分分析儀的66.3%最差；特殊儀器以新莊、輔英兩核心測站的四款微粒粒徑分布監測儀，資料可用率較差。新莊站的資料可用率微米微粒粒徑分布監測儀為43.3%，奈米微粒粒徑分布監測儀為77.0%。輔英站的微米微粒粒徑分布監測儀為71.1%，奈米微粒粒徑分布監測儀經以更新的數據轉換軟體重新取得測值數據後，才得以提升成69.7%。透過嚴密有效的品保查核機制，重大問題如：微粒碳成分分析儀系統漏氣、氣膠散光儀chopper鏡片損壞、微米微粒粒徑分布監測儀粒徑偏移，得以發掘出來並進行矯正。總之，經由本計畫的努力，超測數據有效性得以確保，監測儀器使用期程得以延長。

The goal of this project is to validate monitoring data quality of the aerosol supersite (herein supersite) of the Taiwan Environmental Protection Administration (TEPA) by implementing quality assurance (QA) procedure. To achieve this goal, a regular site inspection at each monitoring station is performed every month and every season. The QA inspection is also applied to the Loon-Bay site moved from the Chiao-Tou site. To improve data quality, this project participates in every supersite maintenance and operation review meeting on monthly and seasonal bases. Meanwhile, an assessment on the weekly data report submitted by the maintenance company has been filed consecutively to the TEPA since April. In addition, a consistent QA procedure was accomplished and applied to all supersites plus the method for eliminating erroneous and unrealistic data further improve the data quality. The data acquisition rate in common instruments across all sites is the highest at 98.6% for PM2.5 aerosol mass monitor and the lowest at 66.3% for aerosol carbon analyzer. The four aerosol size spectrometers at the Hsin-Chuan and the Foo-Yin core sites performed badly this year. The data acquisition rate of micron-particle size spectrometer was only 43.3% and the nano-particle size spectrometer was 77.0% at the Hsin-Chuan site. In contrast, the data acquisition rate of micron-particle size spectrometer was 71.1%, while the nano-particle size spectrometer was increased to 69.7%, after replacing with a new data-conversion-software at the Foo-Yin site. Through a stringent and effective QA mechanism, significant problems such as the leakage of aerosol carbon analyzers, the worn-out of chopper glass of an Integrating Nephelometer, the size shifting of a micron-particle size spectrometer were thus discovered and fixed. In summary, the effectiveness of monitoring data quality is assured and the life of instruments is extended due to the efforts contributed from this project.
