Greenhouse Gas(GHG) Modelling <\/strong> <\/p>\n\n\n\n

Cities are responsible for the majority of global greenhouse gas emissions and therefore play a central role in climate action. To design effective mitigation strategies, it is essential to understand where GHG come from, where they are removed, and how they move through the urban atmosphere. <\/p>\n\n\n\n

We are developing an integrated urban GHG modelling and Bayesian inversion framework to AMB. The framework combines high-resolution biospheric CO2<\/sub> fluxes, anthropogenic emission inventories, atmospheric transport models, and GHG observations<\/a> to quantify the urban carbon budget, identify the contributions of biosphere and human activities to atmospheric CO2<\/sub> , and estimate the uncertainties associated with these calculations.<\/p>\n\n\n\n

The framework can be applied to evaluate and improve greenhouse gas inventories, supporting evidence-based climate mitigation policies and urban planning.<\/p>\n\n\n\n

Extreme Weather-Heat waves<\/strong><\/p>\n\n\n\n

Climate change is expected to increase the frequency, duration, and intensity of extreme weather events, particularly heat waves.<\/p>\n\n\n\n

We are interested in how future climate scenarios with more frequent heat waves (HW) will affect cities. This is especially important to determine the efficacy of strategies of increasing urban green and other land use changes to reduce the effect of HW in the long term.<\/p>\n\n\n\n

Air quality<\/strong><\/p>\n\n\n\n

Urbanisation changes natural landscapes into buildings, roads, and other impervious surfaces, altering local weather conditions and air quality.<\/p>\n\n\n\n

Using WRF-Chem coupled with an urban canopy model, we investigate how changes in land use\u2014such as urban expansion, agriculture, and the development of parks and green spaces\u2014influence urban climate (temperature, wind, and boundary-layer processes) and atmospheric chemistry. We assess their impacts on important air pollutants, including nitrogen dioxide (NO\u2082), ozone (O\u2083), volatile organic compounds (VOCs), and particulate matter (PM). <\/p>\n\n\n\n
