这项研究是使用开源数据库系统进行的，沿着的是印度和全球COVID-19大流行封锁期间全球数据集的连续空气质量监测站结果。我们进行这项研究的目的是研究全球各国在COVID-19疫情封锁期间空气质量和人类死亡率的改善情况。全球空气质量数据来自六大洲超过12，000个连续空气质量监测站，覆盖100多个国家的1000个主要城市。在此，我们讨论了在印度实施的基本空气污染物（如PM 2. 5、NO2、温度、相对湿度和空气质量指数变化）的开源数据集在封锁前和封锁期间的COVID-19大流行期间的实施情况，并描述了全球方面。PM2.5平均浓度（145.51微克/立方米）、NO2平均浓度（21.64微克/立方米）和空气质量指数（55.58）持续下降。PM2. 5（NO2）的变化每年通常超过25微克╱立方米，但于COVID-19封城期间（二零二零年四月）持续下降至20微克╱立方米以下。同样，世界上许多国家的空气质量指数和温度、相对湿度、风速变化等气象因素均显著下降。在亚洲国家，空气质量在全国封城期间有所改善，尤其是在北京、德里和南京等全球污染最严重的城市，以及马德里、纽约、巴黎、首尔、悉尼和东京等发达城市。此外，颗粒物减少约46%，而其他气体污染物于封城期间减少约54%。我们正目睹污染减少，大大改善空气质素。这是由于化石燃料的使用大量减少，这反过来又减少了一般的生产和运输。现在人们愿意看到一个相对健康的世界，有漂白的天空和自然生态系统。这一研究结果表明，在COVID-19大流行期间，空气质量和死亡率的改善带来了潜在的安全效益，导致印度和世界各地的死亡率下降。本文的在线版本（10.1007/s11869-020-00892-w）包含补充材料，可供授权用户使用。
This research was carried out using the open-source database system along with the continuous air quality monitoring station results from global data sets during the COVID-19 pandemic lockdown in India and the global. Our purpose of this research is to study the improvement of air quality and human mortality rates in countries worldwide during the COVID-19 pandemic lockdown. Worldwide air quality data were collected from > 12,000 continuous air quality monitoring stations on six continents covering 1000 major cities from over 100 countries. Here, we discussed the implementation of the open-source data set of basic air pollutants such as PM 2.5, NO2, temperature, relative humidity, and Air Quality Index variation during the pre-lockdown and lockdown pandemic COVID-19 in India and described the global aspect. An average concentration of PM 2.5 (145.51 μg/m3), NO2 (21.64 μg/m3), and AQI index (55.58) continuously decreased. The variation of PM 2.5, NO2, normally shows more than 25 μg/m3 every year, but during the COVID-19 lockdown period (April 2020) continuously decreased below 20 μg/m3. Similarly, the AQI index and meteorological factors such as temperature, relative humidity, and wind speed variation decreased significantly in the many countries in the world. In Asian countries, air quality improved during the national lockdown especially in the most polluted cities globally such as Beijing, Delhi, and Nanjing and also in developed cities like Madrid, New York, Paris, Seoul, Sydney, Tokyo. Furthermore, the reduction of particulate matter was in about 46%, and other gaseous pollutants during the lockdown period were observed in a 54% reduction. We are witnessing pollution reductions which add significantly to improvements in air quality. This is due to the massive decrease in the use of fossil fuel, which in turn reduces production and traffic in general. People nowadays are now willing to see a comparatively healthier world with bleached skies and natural ecosystems. This research finding demonstrates potential safety benefits associated with improving air quality and mortality rates during the COVID-19 pandemic, resulting in decreases in mortality rates in India and around the world.
