→ l19 : 那時候就是數據派 因為看了就能決定220.132.104.86 12/03 00:01
→ l19 : 空氣盒子跟aqi 數字比大概就1:2.5-3220.132.104.86 12/03 00:01
→ l19 : 大概兩年前左右開始 感覺越來越不對220.132.104.86 12/03 00:01
→ l19 : 不管白天 晚上 出門跑步看到的天空220.132.104.86 12/03 00:01
→ l19 : 或燈光 跟以往aqi的數字脫節很明顯220.132.104.86 12/03 00:02
→ l19 : 明明空氣很矇 眼睛會刺痛 還流鼻水220.132.104.86 12/03 00:02
→ l19 : 可是aqi卻不高 對照空氣盒子一堆紫220.132.104.86 12/03 00:02
→ l19 : 查了一下發現 aqi改了計算方式220.132.104.86 12/03 00:02
→ l19 : 之後出門運動 aqi跟空氣盒子對照後220.132.104.86 12/03 00:03
→ l19 : 再決定該不該出門 這樣維持一陣子220.132.104.86 12/03 00:03
→ l19 : 決定不參考aqi 因為完全跟之前脫節220.132.104.86 12/03 00:03
→ l19 : 空氣盒子點多 用多點參考一個區域220.132.104.86 12/03 00:03
→ l19 : 跟外面看到或是感受的情況相去不遠220.132.104.86 12/03 00:03

→ l19 : 空污嚴重時還看過1:1 大概16X:16X220.132.104.86 12/03 00:04
→ l19 : 後來再看aqi 就是看它有數據多離譜220.132.104.86 12/03 00:04
→ l19 : 所以你說要看aqi變綠色 還真不敢信220.132.104.86 12/03 00:04
我不是說叫你看環保署網站,而是叫你去切換空氣盒子app內建顯示指標模式

這會造成什麼差異呢?首先我昨天就貼給你看過,再貼一次,英國指標會造成空氣品質不
錯的假象,因為它把35微克以內都視為不錯,以上到54微克都是中等
但AQI的綠色只到15微克(表擷取自台南市環保局自製對照表,我猜他們用到美國AQI標準
了,所以綠色會是12微克以內),35以上就被標成橘色,54以上跳到紅色,紅色這區間可
視為英國指標的紫色

這會造成什麼差異呢,我擷取目前台中空氣品質給你看過有知道差異
首先是AQI,可以看到整個海線普遍在紅色,明顯有嚴重污染堆積,而市區呈現黃色到紅
色,空氣品質也不好

接著是英國指標,海線因指標分色過細造成看不清楚有個霧霾沉降於此,這先不談,但市
區很明顯出現綠色!這很容易讓人誤判某些地區空氣不錯

綜上所述,我才會建議你改用AQI指標,這跟環保署網站ㄧ點關係都沒有啊......
