The exchange of reactive trace gases and particulate matter (PM) between the atmosphere and terrestrial ecosystems influences air pollution, ecosystems, and climate. Even though land–atmosphere exchanges of reactive gases and PM are expected to evolve with climate and human activities, they are poorly understood from a mechanistic perspective (e.g., Barth et al. 2005 ; Fowler et al. 2009 ; Fiore et al. 2015 ; Kanakidou et al. 2018 ). Advances in the fields of atmospheric chemistry and land

1. Introduction Air pollution episodes in a region can be attributed to high emission levels and favorable meteorological conditions. Most air pollution control strategies are aimed at emissions reductions as a measure to keep pollutant levels in check. The outcome of such strategies depends upon relatively accurate understanding of chemical transformation and long- and short-range transport of primary–secondary pollutant species in the atmosphere. Meteorological variables like temperature

1. Introduction The recent years have seen rapid growth of megacities around the world, especially in South Asia ( Kraas 2007 ); it is estimated that 60% of the world population will live in urban areas by 2030 ( Sokhi 2008 ). This rapid growth of the urban population also brings with it increasing demands for energy-based goods and services, as well as the associated pollution. Urban air pollution has emerged as a major concern for the populations of megacities (cities having populations equal

low-Earth orbits provide observations only once per day and, as a result, are unable to monitor pollution throughout the daytime. Geostationary air quality constellation A new era of satellite imaging spectrometers in geostationary orbit is already upon us. The National Institute of Environmental Research (NIER) of the Ministry of Environment, South Korea, recently launched the Geostationary Environment Monitoring Spectrometer (GEMS; Kim et al. 2020 ) in February 2020 with a field of regard (FoR
