The HMA-LTSER focuses on the Helsinki Metropolitan Area, comprising of the most urbanised part of Finland from the capital city of Helsinki to the city of Lahti 100 km North-East. Monitoring and research on long-term ecological and socio-economic phenomena are carried out by different departments at the University of Helsinki and Helsinki University of Technology under the Urban Studies Network. The cities of Espoo, Helsinki, Lahti and Vantaa, as the network partners, contribute to the LTSER by offering data for research, as well as applying research outputs in planning, policy-making and civic activities. Each of the Urban Studies partner has wide experience in its own field (urban ecosystem studies, urban ecology, urban geography, urban economics, urban sociology etc.), but the HMA-LTSER is a new approach to establish a joint long-term research environment for selected urban sites and themes.

The climate data presented here is based on Normal period of 1981-2010 in Helsinki.
