[AAS09-14] Short-term PM2.5 and black carbon air quality measurements at Qaanaaq, Northwestern Greenland, in the summer of 2023 and the following continuous PM2.5 measurement
キーワード：PM2.5、ブラックカーボン、北極、グリーンランド、大気質
The first air quality measurement on PM2.5 was carried out in Qaanaaq, Northwestern Greenland, in the Arctic region in the summer of 2022 (Yasunari et al., in review; also see the planned presentation at A-CG42 session of JpGU2024). In the summer of 2023 (from July 27 to August 1), we performed PM2.5 measurement at a house there using the commercial version of the PM2.5 measurement system (available via Tanaka Co., Ltd.: http://kktanaka.co.jp/products), which was based on Yasunari et al. (2022). Also, black carbon (BC) measurement was carried out at the same house during the same period, using MA350 (AethLab: https://aethlabs.com/microaeth/ma350/overview). In addition to the short-term observation above, we installed two PurpleAir sensors (https://map.purpleair.com/1/mPM25/a1440/p0/cC0?select=179585#10.85/77.4509/-69.1747) at a guesthouse and school to obtain continuous PM2.5 measurement in Qaanaaq so that the people in Qaanaaq can see the current air quality information anytime. Although the PurpleAir at the guesthouse had some issues after the installation and is unavailable now, the other one at the school has been working well. Therefore, here we show the results from the measured data at the school of Qaanaaq.
Although the PM2.5 highly increased midnight within one hour on August 1, air quality was mostly good during the measurement period. Except for a few cases, the correlations between PM2.5 and BC were primarily low during the measurement period. After installing the PurpleAir sensor at the school on August 1, we observed continuously increased PM2.5 events a couple of times, though the concentrations were low. I will discuss the results more on the day of the presentation.
