Title 101年度鹿林山背景測站科技研究及操作維護計畫
Abstract 基於探討區域性與跨洲際大氣污染傳送對台灣的影響，以及我國背景大氣化學基線資料之建立，環保署於2006年4月13日啟用位於中部鹿林山之空氣品質背景站，進行大氣污染物及大氣輻射長期監測。鹿林山地理位置優越，作為自上游中南半島、中國青藏高原、華南、台灣、西太平洋夏威夷一線大氣污染監測之唯一中繼站，相當具地理優勢及國際水準，足以吸引國際目光，更易於推動國際合作，加入相關國際監測組織，增進我國觀測技術，加強資料交換，並與國際接軌。本年度計畫為第一期（2006-2008年）、第二期（2009-2010年）及第三期(2011)之延續，計畫目標如下： 一、推動參與全球性長程傳輸污染物大氣監測合作、參與國際聯合監測實驗。二、強化監測數據之品保/品管作業，精進維護及管理SOP。三、建立我國空氣品質基線資料，釐清區域、當地污染特徵及變化。四、鹿林山背景測站儀器設備操作維護。 本團隊整合降水化學、微量氣體、大氣氣膠、大氣汞、大氣輻射等主要領域專長研究人員進行相關儀器測試、運轉、操作維護、資料品保品管及分析等技術之建立，並整合協力專業公司進行技術轉移與定期維護，以及開發資料整合系統。推動與美國環保署、太空總署、海洋大氣總署、美國海軍、日本科學界合作，進行技術交流與資料交換。積極參與國際合作，例如7-SEAS國際聯合觀測實驗、聯合國大氣褐雲國際觀測實驗(ABC)、美國太空總署亞洲生質燃燒國際觀測實驗(BASE-Asia)、以及其他有利我國參與之區域合作實驗等，進行實質監測、資料交換、技術交流、參與會議。另分析及比對鹿林山背景測站各項儀器資料，定期執行資料品保/品管作業，確保數據品質。並整合分析自動監測基本資料、各項大氣污染現象特定監測，及氣象資料，以探討鹿林山背景大氣化學特性，區域污染事件日成因，及源區與受體關係。並維持鹿林山背景測站儀器正常運作，維護測站安全。

EngAbstract In order to clarify the intercontinental and regional transport (for instance, acid pollutants, Asian dust, biomass burning and mercury), and to collect the atmospheric baseline data, the Lulin Atmospheric Background Station (LABS, 2862 m MSL), located at Mt. Lulin in central Taiwan, has been operated since 13 April 2006. This project integrates the researchers in the fields of precipitation chemistry, gas chemistry, aerosol chemistry, atmospheric mercury and radiation to test and maintain the instruments, conduct data analysis and construct long-term database. Up to now, total on-site maintenances (includes regular and mobile) are 50 times. The data acquisition rate for aerosols, radiation and meteorological instruments are greater than 90 %, whereas atmospheric mercury and trace gases instruments shows lower rates, due to their complexities.During the project conducting period of January–November in 2012, the average concentrations of CO, O3 and PM10 are about 131.1 ppb, 42.6 ppb and 9.2 g m-3, respectively. The average pH value of precipitation is 5.8. The average concentrations of mercury such as GEM, RGM and PHg are about 1.54 ng m-3, 13.91 pg m-3 and 1.79 pg m-3, respectively. Monthly variation shows the high concentration of pollutants generally occurred during spring time, especially in March. Integrating trajectory analysis and chemical component analysis, we suggest the high concentration events are most likely associated with the biomass burning from SE Asia. The atmospheric background values for CO, O3, and PM10 in Lulin are estimated to be about 115.5 ppb, 36.5 ppb, and 4.1 g m-3, respectively. In addition, we have established intensive international collaborations with USEPA, NOAA, NASA, Japan, and EU countries. We have also participated international experiments or campaigns including UNEP/ABC/EAREX, 7-SEAS, BASE-Asia, and Japan Mt. Fuji Project. The LABS is now part of global networks, for instance, American Mercury network/AMNET, NASA/AERONET, NASA/MPLNET, NOAA /GMD/CCGG sampling network.
