The COVID-19 pandemic enforced nationwide lockdown, which has restricted human activities from March 24 to May 3, 2020, resulted in an improved air quality across India. The present research investigates the connection between COVID-19 pandemic-imposed lockdown and its relation to the present air quality in India; besides, relationship between climate variables and daily new affected cases of Coronavirus and mortality in India during the this period has also been examined. The selected seven air quality pollutant parameters (PM₁₀, PM_2.5, CO, NO₂, SO₂, NH₃, and O₃) at 223 monitoring stations and temperature recorded in New Delhi were used to investigate the spatial pattern of air quality throughout the lockdown. The results showed that the air quality has improved across the country and average temperature and maximum temperature were connected to the outbreak of the COVID-19 pandemic. This outcomes indicates that there is no such relation between climatic parameters and outbreak and its associated mortality. This study will assist the policy maker, researcher, urban planner, and health expert to make suitable strategies against the spreading of COVID-19 in India and abroad.

2020 年 3 月 24 日至 5 月 3 日，COVID-19 大流行实施了全国封锁，限制了人类活动，导致印度各地的空气质量有所改善。本研究调查了 COVID-19 大流行造成的封锁与印度目前空气质量之间的关系；此外，还研究了气候变量与这一时期印度每天新增的冠状病毒感染病例和死亡率之间的关系。选定的七个空气质量污染物参数（PM ₁₀、PM _2.5、CO、NO ₂、SO ₂、NH ₃和 O ₃）在 223 个监测站和新德里记录的温度被用来调查封锁期间空气质量的空间格局。结果显示，全国空气质量有所改善，平均气温和最高气温与COVID-19大流行的爆发有关。这一结果表明，气候参数与疫情及其相关死亡率之间不存在这种关系。这项研究将帮助政策制定者、研究人员、城市规划者和健康专家制定适当的策略来应对 COVID-19 在印度和国外的传播。
