Delhi had 192 ‘good air’ days due to lockdown

All attention was focused only on the insidious coronavirus during the passing year, so not many realised that in 2020, Delhi enjoyed the most good-air days of the past three years. There were 192 days when the PM2.5 level was below the National Ambient Air Quality Standard of 60 micrograms per cubic metre. In contrast, there were just 120 such days in 2018 and 145 in 2019, according to System of Air Quality and Weather Forecasting and Research (SAFAR), the forecasting body under the Union ministry of earth sciences.
