This November, unfavorable conditions led to widespread pollution, with over 30 cities issuing heavy pollution alerts. The Ministry of Ecology and Environment, in collaboration with other agencies, launched a three-year action plan to combat severe pollution events, focusing on key regions such as the Beijing-Tianjin-Hebei area, Fenwei Plain, Northeast China, and the northern slope of the Tianshan Mountains. Using data from over 4,000 monitoring stations covering all cities above the prefecture level, #BlueMap presents hourly air quality data for November, visualizing the spatial and temporal distribution of heavy pollution, tracking haze and dust transmission paths, and providing insights into atmospheric pollution patterns. Defending blue skies requires greater attention and collective action!

In September, high temperatures and drought in the south gradually alleviated, while the northwest experienced multiple sandstorms. In North China, ozone levels remained elevated in areas such as the mountain plains and the Bohai Sea region. The Beijing-Tianjin-Hebei area recorded an average PM2.5 concentration of 34.3 μg/m3 in the first three quarters, meeting the secondary standard for the first time.

In August, the Yangtze River Basin experienced widespread high temperatures, with the Sichuan-Chongqing region frequently making headlines due to the heat. Meanwhile, northern China enjoyed pleasant early autumn temperatures, with overall good air quality. In the Beijing-Tianjin-Hebei region, the monthly average PM2.5 dropped to a historic low, and the cumulative average for the first eight months fell below 35 micrograms, meeting national secondary air quality standards for the first time.

This June, widespread high-temperature warnings swept across northern regions, with ozone levels rising significantly year-on-year in cities within the Beijing-Tianjin-Hebei area and its surroundings. In contrast, South China experienced above-average rainfall, bringing the monthly PM2.5 average in the Pearl River Delta down to single digits. Using data from over 4,000 monitoring stations covering all cities above the prefecture level, #BlueMap presents air quality dynamics for June, visualizing the spatial and temporal distribution of heavy pollution, tracking haze and dust transmission paths, and providing insights into atmospheric pollution patterns.

In May 2022, Northern China experienced high temperatures and elevated ozone levels, while Southern China saw widespread rainfall and Northeast China endured strong winds and cold waves. Among the 168 key cities, PM2.5 levels dropped by 8.4% year-on-year, while ozone levels rose by 10.3%. Using data from over 4,000 monitoring stations covering all cities above the prefecture level, #BlueMap presents air quality dynamics for May.
