PM1.0在臺中地區的污染來源大概是什麼 7. 針對能見度影響因子(諸如粒徑、**VOC成分**、PM成分、濕度影響等),與能見度之影響因果關係,建議建立各項因果關係,以利判定能見度劣化成因及空氣品質分析。 --- 境外污染SOP 選出日期可以參考 [台中市政新聞](https://www.taichung.gov.tw/8868/8872/9962) ## 期末報告 112 年 11 月 30 日前 提出 1. 完成兩測站各即時數據及化學成份分析整理 2. 完成兩測站能見度影響因子與貢獻探討 # 可以加的圖 (有看到什麼不錯的可以放上來) 1. ![](https://i.imgur.com/jXZxN1d.jpg) 2. ![](https://i.imgur.com/rjn44I2.png) 3. ![](https://i.imgur.com/xzS1d7R.png) ## Idea [Open air](https://bookdown.org/david_carslaw/openair/sections/intro/intro.html) 1. 長期趨勢 * [Theil-Sen estimates](https://davidcarslaw.github.io/openair/reference/TheilSen.html): 針對有顯著下降的物種進行進一步分析,討論其下降對能見度是否帶來影響 * 計算SOR、NOR、ALWC並比較歷年趨勢 * 要粒徑分布的資料,計算消光重建 2. event 根據**奕翰的分事件依據**,應該可以去比較 * 春夏秋冬事件的差異 * 事件可以分成 PM1主導 | PM1-2.5主導 | 均增加 三類去討論其差異 * 或許可以多做幾年 甚至長期? 但長期的粒徑資料無法merge,可能沒辦法做上面那項,資料處理也很麻煩 3. Deweather之後的trend 4. 加沙塵暴進去 5. 春季新增事件 6. 手動採樣期分析 # 要和老師討論的方向 ## 長期趨勢 1. 要粒徑資料 (raw data) ->才可以跑PMF | 比較長期粒徑分布 2. DN-VC 後比較歷年趨勢 3. 事件 | [其他分類依據?] * 發生頻率 - 是否受到季節影響 * 時間長短 * 固定SOP、分類依據 * 氣象條件 * 事件劣化的強度 -> 看是因為氣候影響 還是改善不夠 4. PMF (化學 | 粒徑) * 分季節 * 分年分(再分月份) * 提PMF困境:數據量大 一次跑一個月應該差不多 * 5. 境外污染事件 (class by 台中市政府) [台中市政府](https://www.taichung.gov.tw/10179/12878/?q=%E5%A2%83%E5%A4%96%E6%B1%A1%E6%9F%93&btnsearch=%E6%9F%A5%E8%A9%A2#gsc.tab=0&gsc.q=%E5%A2%83%E5%A4%96%E6%B1%A1%E6%9F%93&gsc.page=1) 6.

PMF(basic | IGOR) * 考量VOC反應性 (IGOR | 四維的) * 楊老師、丁老師有IGOR 可以先試用 * PMF統一方法 * 1. 只有做今年 交今年的PMF結果 * 2. 沒做 只拿俊發的結果來回應委員 * 3. 長期趨勢 哪幾年比較酷 可以拿出來做PMF * 化學部分 著重在手動採樣跑PMF * ICP比較正確 * 怕手動的data Q的不好 * 手動數據若怪怪的 就不要再做下去 * 化學成分和粒徑分布一起丟 會解得比較好 5. 境外污染事件可以後面一點做 比較像是找到不是我們自己造成的事件 再來討論境外污染 6. 設定目標 到11月底 哪些可以做完 * 減少機制面 著重在如何應用 * 列出時間表 弄一個Google calender * ## 事件 1. PM1和大顆粒主導事件討論 2. PMF 3. GR_surf + CS rate 4. 化學成分分析 5. Start | Increase | Peak | Decrease | End --- 1. 逆軌跡PSCF可以用在事件的分析 2. hy_split? NOAA 逆軌跡演算 3. 不同季節的事件 * 和長期作法類似 4. ## 子哲 1. 臭氧跟VOC的關聯: 若相關性佳,可以透過VOC的來源制定臭氧的減量策略(PMF+PSCF) 3. 健康風險評估(VOC、O3) 4. SOAP & SOC 的相關性 5. AOC=Ox/CO 6. --- 1. 延伸冠頡的內容 2. AOC要跑楊老師的MCM 3. 希望可以了解VOC對Nitrate和O3的角色 4. 哪些排放源 需要管制(機制 期中報告已提出 大概就是那樣) * 有無季節性的差異 * ## 警示和改善 1. --- 1. 獨立一個章節 整合前面提到的警示和改善 2. 找顧問審閱?楊樹章? 3. PMF比較重要 對於警示和改善 ## 我們各自的研究@@ ### Sylvie ### Harry 1. 化學+粒徑對消光的PMF 討論不同情況下的AAE 1. 重算ALWC,重抓PBL資料 2. Theil-Sen trend 5. Deweather
