In May of 2022, the World Meteorological Organization Research Board’s COVID-19 Task Team released a set of lessons learned regarding Meteorological and Air Quality Services for COVID-19 Risk Reduction and Management. These findings were based in part on the Task Team’s March 2021 Review on Meteorological and Air Quality Factors Affecting the COVID-19 Pandemic and were further informed by evidence published after that Review. In order to provide a formal update on the Review, the Task Team commissioned and accepted an updated umbrella review that summarized the evidence of meteorological and air quality influences on the pandemic provided in review articles published through April 2022. The commissioned review updates and confirms the evidence basis for the Key Findings that the Task Team issued in May 2022.
