　　據《science》28日最新消息,一款可實時監測空氣品質狀況的新型儀器問世。

　　霧霾在身邊,中國空氣汙染已成為人們心中「會呼吸的痛」。據報導,每年因為空氣汙染而死亡的早產新生兒達1600百萬,觸目心驚的背後使我們不得不面對的現實。

　　基於這種現狀,考慮到家人的健康狀況,位於北京的數據科學家Yann Boquillod有些坐不住。他出資創建了名為AirVisual Earth的智能空氣品質檢測器,該檢測器可根據人造衛星和超過8000個的監測站提供的信息,通過整合數據處理,實時觀測,展現全球空氣汙染狀況。

　　這種空氣品質檢測器主要通過展現風向的流動模式和通過不同顏色表示PM2.5(指空氣動力學直徑小於等於2.5微米的細顆粒,可吸入細支氣管和肺泡中,對人體危害極大。)的濃度來體現空氣品質狀況。用戶可放大,傾斜,旋轉以便更好地觀看。

　　Yann Boquillod指出,這樣是為了讓人們能更深入的了解空氣品質狀況,從而為下一步更好的治理空氣汙染做好打算。除此之外,他還為智慧型手機提供了一款可觀測600多個不同城市未來三天空氣品質的軟體,最近它已經開始低價售賣,用戶可通過其實時觀測室內和室外空氣品質狀況。

　　Watch air pollution flow across the planet in real time

　　China’s air is notoriously toxic: Each year, it contributes to the premature deaths of some 1.6 million people. Concerned about how such pollution was affecting his family, Beijing-based data scientist Yann Boquillod founded AirVisual Earth, an online air pollution map that uses data from satellites and more than 8000 monitoring stations to display global air pollution in real time. The AirVisual Earth interactive maps prevailing wind patterns and shows color-coded concentrations of PM2.5—airborne particulate matter less than 2.5 microns in diameter that can penetrate deep into the lungs. Users can zoom in, tilt, and spin the globe for better viewing. The air pollution visualization was crafted 「so people really understand how bad it is,」 says Boquillod, who hopes an informed citizenry will pressure governments and communities to clear the air. AirVisual also delivers 3-day air pollution forecasts for 6000 cities to smartphones, and it recently began selling low-cost monitors people can use to track indoor and outdoor air pollution. 「People want to share that data,」 Boquillod says.
