![]() LULCC affects the global concentration of greenhouse gasses, often times removing vegetation and forest cover that acts as a natural carbon sink. The impacts of LULCC are often complex as they occur in the context of a warming climate. Land use and land cover change (LULCC) can significantly contribute to overall climate change. Observational and modelling studies are welcome, as well as qualitative and mixed methods research and work that employs novel sensing or simulation techniques, big data products, and machine learning. We are also interested in studies that help build community resilience to extreme events, support decision-making, and potentially transform policy and practice. ![]() We welcome submissions of interdisciplinary and transdisciplinary teams and encourage collaborative studies with practitioners, stakeholders, city managers, emergency responders, NGOs, and partners from industry. This session solicits outcome-focused studies that address critical issues in the urban atmosphere and their impacts on people, communities, and society. This requires a paradigm shift from urban adaptation and mitigation solutions to personal and societal outcomes if those solutions were to be implemented. the people who live in cities, social structures, and public policy implications. Moving forward, the impact of the built environment on urban climate cannot be considered in isolation it needs to be examined holistically in the context of the human environment, i.e. How we (re)design cities will play a major role in alleviating climate stressors and building community resilience to extreme events as the world continues to urbanize. This session welcomes contributions from laboratory, field, and modeling work on basic CCN and ice nucleation processes, the development and model application of cloud microphysical parameterizations, ground based and aircraft based CCN, INP and cloud microphysics measurements, as well as new instrument and method developments for measuring CCN, INPs and cloud microphysical processes. ![]() Ongoing effort in laboratory, field and modelling work aims at better understanding, quantifying and modelling basic cloud condensation, ice nucleation and precipitation formation processes at scales from the microscopic to the global level. These direct impacts of aerosol particles on cloud formation are followed by a variety of secondary processes like coalescence, riming, or ice multiplication, which play major roles in the life cycles and climatic impact of clouds as well as the formation, distribution and intensity of precipitation. ![]() A large fraction of atmospheric aerosols acts as CCN (cloud condensation nuclei), but only a very minor and strongly temperature dependent fraction called INPs (ice nucleating particles) contributes to the primary ice formation in both mixed-phase and cirrus clouds. ![]()
