A team of 10 interdisciplinary researchers from the University of Surrey’s renowned Global Centre for Clean Air Research (GCARE), including PhD students and post-doctoral researchers, have united to develop a rapid assessment of the impact COVID-19 has had on air quality.
Figures from the World Health Organisation show the ongoing pandemic has caused more than 477,000 deaths worldwide as of June 2020, 14,000 of which occurred in India.
