Abstract

Abstract The 2021 The Air Quality and Climate Change (1st AQCC) and The 3rd Malaysia Air Quality Annual Symposium (MAQAS) organized by Clean Air Forum Society of Malaysia (MyCAS) and supported by Department of Environment Malaysia (Air Division) and Taiwan Association for Aerosol Research (TAAR) was held on the 17th–18th November 2021 in virtual form. Due to the Covid-19 pandemic, “Combating Climate Change and Improving Air Quality in a Global Pandemic” was chosen as the theme of this year’s conference. High challenges have been faced by our team members to manage this event due to the Covid-19. However, with the collaboration and hard work among committee members and participants this event was successfully conducted virtually and managed remotely from Bangi Resort Hotel, Putrajaya and from University Malaysia Terengganu as a second centre. With that, the conference had emphasized interdisciplinary research along with practices and fosters exchanges among tiscientists, practitioners, professionals and young researchers in finding solutions and sharing latest technology in aerosol and air quality studies and work during this situation. It was an honour to receive more than 50 papers submitted to the conference and I am very pleased to announce that around 17 papers have been selected to be published in the IOP proceeding. All papers which have been accepted were subjected to a rigorous peer-reviewing process to ensure quality and consistency. Hence, it is vital to tackle air quality issues. The conference also served as an opportunity in establishing networking among scientists, practitioners, professionals and young researchers in international regions in strengthening international collaboration. A wide range of topics was covered from fundamental, applied and technology aspects of aerosol science and air quality that focused on monitoring, control strategies, health impact, policy and management, big data and air pollution modelling using earth observation data, atmospheric transport and emissions from combustion process. I acknowledge with gratitude the assistance rendered by the scientific team of 2021 AQCC and MAQAS was led by Prof. Dr Juliana Jalaludin and her publication team along-with all the track chairs with continuous support and advice led to the smooth publication of this issue. Last, but not least, we thank the authors, reviewers and the conference secretariat for their contribution which has enabled this publication to become a reality. Hopefully, all participants and other interested readers will benefit scientifically from the proceedings and also find it stimulating in the process.
