However, as the government relaxed more restrictions in the recovery MCO beginning June 10, air quality started to dip. Boosts in air quality were recorded for all stages of the MCO, but such improvements became less apparent in the recovery MCO period between June 10 and 22. Based on the DOE’s readings, air quality improved the most, or by 53% during the conditional MCO phase between May 4 and June 9. And during the recovery MCO from June 10 to June 24, people spent about 5% to 15% more time at home. When the recovery MCO kicked off on June 10 – a phase which lifted the ban on interstate travel, the air quality improved by only 32% compared to pre-MCO days.
