In addition, natural scents from plants, and experimental music - made up of nature-like sounds (breeze, water, birds) are employed to provide a soothing experience while walking inside the pavilion. All of these inventive methods could further be applied to solve air pollution in other kinds of design. © Napon Jaturapuchapornpong At an individual level, a personal mobile suit equipped with a portable air filter could be manufactured, allowing users to move around refreshed. Looking wider at an urban scale, bus stops, recreational space under expressways, and skywalks also have the potential to be revitalized with such purification systems. In the end, even high-rise buildings might become old-fashioned when

Global tropospheric ozone responses to reduced NOx emissions linked to the COVID-19 worldwide lockdowns

Abstract Efforts to stem the transmission of coronavirus disease 2019 (COVID-19) led to rapid, global ancillary reductions in air pollutant emissions. Here, we quantify the impact on tropospheric ozone using a multiconstituent chemical data assimilation system. Anthropogenic NO x emissions dropped by at least 15% globally and 18 to 25% regionally in April and May 2020, which decreased free tropospheric ozone by up to 5 parts per billion, consistent with independent satellite observations. The global total tropospheric ozone burden declined by 6TgO 3 (∼2%) in May and June 2020, largely due to emission reductions in Asia and the Americas that were amplified by regionally high ozone production efficiencies (up to 4 TgO
