为一个城市的空气污染问题制定有效的清洁空气行动计划需要一个广泛的监测站网络，以代表空间和时间模式，并了解造成问题的根源。在印度，2019年启动了国家清洁空气计划(NCAP)，为131个未达到目标的城市制定清洁空气行动计划，其中包括开展来源分配研究和建立排放基线。截至2023年2月，只有39个城市完成了分摊研究。在本文中，我们提出了加强环境空气监测网络所需的必要资源，以设计具有代表性的风场大小、采样大小和采样频率，以有效跟踪城市在改善空气质量方面所取得的进展。NCAP计划的城市被划分为104个空气污染区(占全国面积的5.3%)，总共代表164个城市，总人口2.95亿(占全国总人口的21%)。在这些空港中，73个只包含一个城市；18个包含两个城市，9个包含三个城市。德里、孟买、印多尔和昌迪加尔四个机场分别包含10个、8个、5个和5个城市。为量度和分析空气中的颗粒物污染，104个空气仓建议共设置2118个采样点。各城市可以考虑混合监测网络，用低成本/传感器级别的高密度监测网络来补充现有的监管监测网络。制定空气集散区一级的空气质量管理计划、加强监测网络以及整合排放源信息，对于优化《国家清洁空气行动计划》下的清洁空气工作至关重要。
Building an effective clean air action plan for a city's air pollution problem requires an extensive network of monitoring stations to represent spatial and temporal patterns and an understanding of the sources contributing to the problem. In India, the National Clean Air Programme (NCAP) was launched in 2019 to develop clean air action plans for 131 non-attainment cities, which includes conducting source apportionment studies and establishing emission baselines. As of February 2023, only 39 cities have completed the apportionment studies. In this paper, we present the essential resources needed to strengthen the ambient air monitoring networks, for designing a representative airshed size, sampling size, and sampling frequency, to effectively track the progress made in the cities for better air quality. The NCAP cities were grouped into 104 airsheds (5.3% of the national area), collectively representing a total of 164 cities and a total population of 295 million (21% of the national total). Of these airsheds, 73 contain only one city; 18 contain two cities, and nine contain three cities. Four airsheds – Delhi, Mumbai, Indore, and Chandigarh contain 10, 8, 5, and 5 cities respectively. To measure and analyse particulate matter pollution, a total of 2118 sampling sites are recommended for the 104 airsheds. Cities could consider hybrid monitoring networks by complementing existing regulatory monitoring network with a high-density network of low-cost/sensor-grade monitors. An airshed level air quality management plan, an enhanced monitoring network, and consolidation of information on emission sources, are crucial for optimizing the clean air efforts under NCAP.
