本計畫主要針對環保署現有監測站執行不定期品保作業，確保維護作業及監測站網監測數據品質。計畫工作內容包括(1)執行監測站儀器績效查核共80站、及績效查核複查10站、(2)執行監測站功能檢查共486站、(3)每季提交監測數據季評估報告。 績效查核主要評估監測數據準確度，本計畫總計完成80站次績效查核，總查核項次為1457項次，未達查核品質標準共58項，整體滿意率96.0%，為近五年查核滿意度最低(96執行年至99執行年整體滿意率分別為：96.2%、96.2%、96.8%、96.5%)。各監測儀器類型查核滿意度，以氣狀物監測儀平均滿意率99.9%為最高，粒狀物監測儀平均滿意率97.6%居次，而動態稀釋校正器平均滿意率89.4%為滿意率最低的監測儀器。為將查核結果更貼近監測數據準確度，本計畫另新增超低濃度查核及測站零空氣查核比對兩項工作。 功能檢查主要不定期對測站站房設施設備、文件記錄狀況、監測儀運轉狀況、異常數據檢查及測站儀器準確度狀況等進行完整之檢查評估。本計畫總計完成486站次功能檢查，總檢查項次達68175項，共發現325項檢查缺失，缺失率0.48%。近五年整體檢查缺失率有下降趨勢。各檢查類型缺失發生率依序為準確度檢查之1.38%、站房設施設備之0.51%、氣象儀器設備之0.38%、監測儀器之0.33%、文件紀錄之0.15%。 另為了解整體監測儀器運轉狀況及管理狀況，本計畫共提交了4次監測數據季評估報告，報告內容除包括品保執行結果外，另針對維護管理事項、監測資料可用率等方面進行整理綜合彙整分析。

This project executing period was from May 8th 2011 to May 7th 2012. The main purpose of this project is aiming at non-periodically inspecting and auditing all current Environmental Protection Administration’s Air Quality Monitoring Stations to guarantee the quality of monitoring network data. The work content mainly included (1) the execution of monitoring instruments performance audit 80 stations, (2) the execution of monitoring instruments functional check 486 stations, (3) submit the quarterly reports of monitoring data quality. The performance audit primarily inspected the deviation between the monitoring value and the standard value (accuracy), there were 80 stations completed in this year , audited items total was 1457, just 58 items does not meet the audit quality objectives, the degree of satisfaction was 96.0%, it’s the lowest satisfaction degree in recent five years. According to the monitoring instrument type, the highest satisfaction degree was 99.9% performed by gaseous monitoring instruments, the second one was 97.6% done by particle monitoring instruments and the lowest one was 92.8% done by dynamic dilution calibration system. To ensure the performance audit results closer to the monitoring data accuracy, new work items is ultra-low concentrations of checking, and zero air purity check in this project. Functional check was mainly to focus on non-periodically surveys and assessments on stations house maintenance, facility equipments, the document recording, the monitor operation conditions, the monitoring data check and the monitoring instruments accuracy inspection. There were totally 486 functional checks in this year ,checked items total was 68175, just finded 325 items missing, the whole result of functional check demonstrated the defect rate only 0.48%. Which presented declining trend year by year due to the high quality in sustaining operation and maintenance of monitoring stations. According to different kind of functional check result, the unqualified defects were shown in sequence. The highest defect rate was accuracy check 1.38%, the second was station & facility equipments 0.51%, meteorological instruments 0.38% is third, then malfunctioned monitors 0.33%, and finally document recording conditions 0.15%. In order to assessment the quality of monitoring data and maintenance management condition, total submitted 4 times quarterly reports of monitoring data quality, the report content included the results of quality assurance, the maintenance management conditions, the availability of monitoring data, and another related contents.
