The Contribution of GHG and SLCP To Global Warming And Climate Change In Urban Areas

About this Research Topic

Over half of the world's population live in urban areas, which are projected to house 60% of the population by 2030. These areas are expanding in all parts of the world, and are recognized as important atmospheric sources of greenhouse gases (GHG) and of short-lived climate pollutants (SLCP). The SLCP are gases and particulates that are also responsible for global warming not caused by CO2 and have an atmospheric lifetime of less than 20 years. The emissions, fate and atmospheric concentrations of these species will be affected by economic growth, governmental policies of pollution control, climate change, leading to expected modification of temperature and humidity, specifically by the atmospheric temperature, and by extreme hydrometeorological events. This knowledge became more urgent after the Paris Conference between the Parties (COP21) signed in December 2015.

Countries are asked to develop GHG emission inventories and programs for their reduction targets to 2030 and 2050. But there is a great deal of uncertainty in top-down inventories and there is an initiative in several countries to monitor the concentrations and flows of CO2 and CH4. However, there are few urban areas with GHG measurement networks, even those that are responsible for large emissions of GHG and SLCP on a global scale. In addition to emission inventories uncertainties, they also do not consider all the sectors, and specific sources of local process of energy generation, domestic cooking, heating, and air conditioning. This Research Topic will aim to highlight the latest advances on how GHG and SLCP are contributing to global warming and climate change in urban areas. We will focus on the recent advances on surface and remote measurements, source appointment and emission estimates of GHG and SLCP in urban areas.

Topics of interest include but are not limited to:
• GHG emissions and measurements in urban areas
• CH4 emissions and concentrations in urban areas
• SLCP emissions and measurements in urban areas
• Surface O3 measurements in urban areas
• Chemical and optical properties measurements of atmospheric aerosols
• Impact of SLCP in radiative balance and microphysics process
• Non-conventional sources of SLCP
• Inventories improvement based on GHG measurements


Keywords: Greenhouse gases, short-lived climate pollutants, urban areas, GHG measurement networks, global warming, climate change, surface and remote measurements, CH4, emissions
