Overview
South and Southeast Asian countries cover a total area of 9.75 million km2 and with a sizeable population exceeding 2.36 billion people. They represent almost 30.66% of the world’s population in only 6.57% of the world’s land area. Several major cities in South/Southeast Asia have air quality issues with Greenhouse gases (GHG), Short-Lived Climate Pollutants (SLCP) and aerosol emissions. The most common GHG pollutants include CO2, CH4, and N2O, whereas the SLCP’s include both warming agents (black carbon particles and ozone precursor gases such as NOx, NMVOC and CO) and cooling agents (organic carbon particles and SO2). Similarly, aerosols can influence climate by scattering light and changing Earth's radiation budget, and can also alter the climate via cloud interaction. Quantifying the GHG’s, SLCP and aerosol emissions from different sectors such as from energy, transportation, urban, waste and industries is important to address the air quality problem. In addition to emissions from these sectors, biomass burning in S/SEA is the most common phenomenon. Biomass from forest fires and crop residue field burning contributes significantly to emissions. The smoke and aerosols from large-scale biomass burning activities can rise high into the troposphere and be carried long distances by wind currents affecting air quality on regional scales. Although important sources of these pollutants are known, large uncertainties exist in the literature. Thus, a detailed quantification and understanding of GHG’s, SLCP’s and aerosol emissions, their drivers, states and impacts gain significance in South/Southeast Asian countries. Information on emission sources and their spatial and temporal distributions is important for air quality management and to arrive at best management practices and mitigation strategies.
Recent advances in instrumentation have resulted in improved air quality measurements to characterize atmospheric composition. Laboratory and field in-situ measurements combined with satellite remote sensing and geospatial technologies are enabling sampling of pollutants and pollutant episodes in challenging conditions. Integrated methodologies combining both top-down (using field-based measurements, remote sensing and geospatial technologies) and bottom-up (using activity data and emission factors) approaches are being developed for improved emission estimates across broad spatiotemporal scales. Weather and chemistry integrated models combined with observation data are being used to address the wide range of questions regarding emissions, their transformation, transport and deposition at a variety of scales. In addition, models are also being used to assist in air pollution health risk assessments and to communicate the impact of pollutants on different socio-economic, environmental and policy circumstances. The purpose of this Special Issue is to solicit updated research on the above aspects in South/Southeast Asian countries. The following themes are of interest:
- Measurement data from land-based stations, ship-based platforms, space-based satellites, and other platforms on GHG’s, SLCP’s and Aerosols linking with Environmental Pollution;
- Quantifying biomass burning pollutants/pollution episodes, drivers and impacts on environmental pollution at local to regional scales;
- Quantifying the impact of environmental pollutants on local/regional climate;
- Remote sensing of air pollutants and characterizing air pollution episodes from different sources/sectors;
- Geo-sensor data networks for air pollution mapping, monitoring and modeling;
- Integrating top-down (remote sensing, geospatial technologies) and bottom-up (field measurements) for quantifying environmental pollution episodes/pollutants;
- Emission inventories development and validation;
- Urban heat island effect and pollution;
- Biogenic volatile organic compounds and pollution;
- Chemical transport modeling;
- Integrated assessments involving air quality and societal benefit.
