Leena Järvi (PhD) is Professor in Urban Meteorology and leads the urban meteorology group. Her research expertise lies in urban meteorology, climate and their interaction with 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 and how to reduce their uncertainties, urban land surface modelling and urban LES. She is PI of the two eddy covariance stations located in Helsinki, with one of them being the ICOS Associated Ecosystem site. 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.

D.Soc.Sc. Rosa Rantanen works as a Research Coordinator in the CO-CARBON project. Her background is in practical philosophy and she has also worked for NGO’s and humanitarian organizations. She is specialized in interdisciplinary approaches and social inclusion. In CO-CARBON she focuses on general coordination, stakeholder engagement, and creating new ideas and social impact.

Joyson Ahongshangbam (PhD) is working as a Postdoctoral Researcher in the CO-CARBON project. He will focus on quantifying carbon fluxes and storage in urban green areas. His research interests lie in forest carbon and water cycle studies through measurements, modelling and remote sensing applications. 

Nahid Atashi (PhD) works as postdoctoral researcher at the CousCous project. She will focus 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.

Yiyang Ding (Ph.D) is a joint postdoctoral researcher working in CarboCity project (urban ecosystem) and TWINWIN project (agricultural ecosystem). Her research focuses on soil-root interface and below- and above-ground carbon (C) fluxes in forest/urban/agricultural ecosystems. Over 10 years of studying soil ecology, she considered that the fine roots and their symbionts could significantly affect soil C storage and nutrient cycling in northern hemisphere.

Pak Lun Fung (PhD), also known as Alan, is working as a postdoctoral researcher in the project Artificial Intelligence for Urban Low-Emission Autonomous Traffic (AIforLEssAuto). In the project, he will focus on carbon dioxide emission modelling under different driving scenarios in urban areas by exploring new spatial models. He is interested in combining machine learning methods with physics-based atmospheric models and remote sensing applications. He is also passionate about bridging science and art via data visualization and sonification.

Yaxing Du (PhD) works as a visiting researcher in the group as part of the CousCous project. She will focus on simulating the different air quality fields within urban neighborhoods and including to study the impact of turbulent transport and ventilation on the concentration fields. She is interested in understanding air quality and outdoor thermal comfort in urban environment within neighborhood scale.

Minttu Havu (MSc)  is a doctoral researcher working with urban carbon dioxide surface exchange and added it as simulated component to the Surface Urban Energy and Water Balance Scheme (SUEWS). She is also working with simulating urban soil respiration with soil carbon model Yasso. She is interested on how different planning options can impact the spatial and temporal variability of carbon dioxide exchange.

Sasu Karttunen (MSc) is a doctoral student in meteorology working with urban boundary layer with focus in coastal cities. He utilises Lidar and DTS measurements together with LES modelling  to understand development of urban boundary layers including the interaction with water bodies.

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.

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.

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.

Jesse Soininen is an undergraduate student from the University of Helsinki working with CarboCity and CO-CARBON projects.
