Leena Järvi (PhD) is Professor in Urban Meteorology and leads the urban meteorology research group. Her research expertise lies in urban meteorology, climate and air quality using state-of-the-art observations and modelling at different urban scales. She has expertise in urban eddy covariance measurements of variety of compounds , urban land surface modelling and urban large eddy simulation. She is PI of the two eddy covariance stations located in Helsinki, with one of them being the ICOS Associated Ecosystem station FI-Kmp. She has been developing the Surface Urban Energy and Water balance Scheme (SUEWS) and the parameterisations within. Currently her research interest lies in urban carbon storage, impact of meteorological conditions on local air quality distributions and how cities should be planned from the atmospheric perspective.

Omar Al-Jaghbeer (MSc) is a doctoral student working with carbon emission modeling in the PAUL project

Nahid Atashi (PhD) works as postdoctoral researcher at the Urban Meteorology Group. She focuses on applying high-resolution air quality simulations in planned city boulevards in Helsinki using large eddy-simulation modelling (LES). She is interested in understanding air quality in different levels in the urban environments and conducting atmospheric sciences to provide urban planning solutions in order to improve the local air quality.

Veera Bilaletdin is an undergraduate student working with greenhouse gas exchange in urban green areas. She is working in the GHUGHS project.

Minttu Havu (PhD) is a postdoctoral researcher working with urban biogenic GHG cycles and urban heat islands. 

Yiling Hu (MSc) is a doctoral student studying the impacts of electric vehicle (EV) adoption on urban air quality, with particular focus on non-exhaust emissions (NEE) and secondary organic aerosol (SOA) formation. She utilizes the LES model PALM coupled with the aerosol module SALSA to investigate how mixed traffic fleets shape aerosol concentrations in urban street canyons. 

MSc Anni Karvonen is a doctoral researcher with a focus in simulating urban biogenic carbon sinks and surface energy balance using SUEWS model. She works with ICOSCities project.

Hei Shing (Michael) Lee is a doctoral student primarily focusing on the urban land surface model SUEWS in relation to urban green space. His MSc in Atmospheric Sciences enables him to utilize atmospheric observations, develop SUEWS and perform model simulations for his doctoral research which is part of the projects CarboCity and CO-CARBON.

Xiaoyu Li (MSc) is a doctoral student working with urban air quality and formation of urban aerosol particles. She will use comprehensive air quality observations for different global cities as well as the LES model PALM in her research. Particularly she will further evaluate and improve the sectional aerosol module in PALM.

PhD Kaisa Rissanen is a postdoctoral researches tudying different aspects of urban tree physiology and vitality, including tree water relations, growth, acclimation and emissions of volatile organic compounds (VOCs). Her current project, funded by Kone Foundation, explores the impacts of varying urban growth environments on tree functioning, vitality and stress, with the goal of better quantifying the spatial drivers of urban tree ecosystem services and disservices.

MSc Jesse Soininen is a doctoral researcher conducting measurements of carbon uptake by urban green spaces. He focuses on eddy covariance flux measurements of carbonyl sulfide (COS) and CO2, which are supported by chamber measurements of CO2 urban parks. His work contributes to CO-CARBON and ICOS-Cities projects.

Jani Strömberg (MSc) is a doctoral researcher using LES modelling to study turbulent transport processes in an urban boundary layer. His work aims to reduce uncertainties in greenhouse gas emission measurements for better interpretation and design of EC setups in the ICOS-Cities project.

PhD Qian Wang, funded by the China Scholarship Council, is joining the group as a postdoctoral researcher for two years. She is a lecturer at Changsha University of Science and Technology. Her research focuses on tree eco-physiological functioning, particularly the water relations of trees in both urban and forest environments.
