Site Description
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 ...

Geology
All the catchment areas of Helsinki are located on microline granite (1.82-1.84 Ga) bedrock. In Lahti the cathment areas of studies are located on mica schist and mica gneiss bedrock except for intermediate land-use are that is located on microline granite.
Vegetation
There is some remnant forest patches in high land-use intensity sites. The low-land-use intensity sites are typified by larger areas of remnant forests and yards of single-family houses. Catchment areas with intermediate land-use intensity are best described as strongly urbanised sites with cs. 50 % of the areas being impervious. The remnant forests are typically coniferous forests with Scot´s pine (Pinus sylvestris) as the dominant tree. In urban parks the uppermost organic layer of the soils autochtonous by nature and compacted by trampling.
Soils
The soil profile of the three areas in Helsinki consists of homogeneous clay and silt stratification as well as pre-quaternary bedrock outcrops. The soil type of Lahti´s areas is for the most part gravel and san till, but the most intensive land-use area is located on Salpausselkä I terminal moraine formed in the latest ice age during the Younger Dryas era 12 000 BP. The soils within the catchmens represent typical urban mosaic with a diversity of topsoils.
Hydrology
Hydrological aspects are being studied in sub-catchments in both Helsinki and Lahti. On each catchment area s discharge point sensor are monitoring the quality (turbidity, conductivity) and quantity in real time and collecting the data. Samplers are taking samples continually and the equipment produces data throughout whole year. Winter time surface water is studied as well. The water samples are analyzed for nutrients and trace elements as well as suspended solids and dissolved material.

Equipment notes
The estimate covers a total of seven measurements settings, each consisting of precipitation tipping bucket and its logger, and the devices in the urban stormwater monitoring site. These sites consists of runoff probe (ultrasound), and sensors for turbidity, conductivity, and temperature. Additionally, all the sites have their own sampler, a freezer, a logger for data saving, and a modem which enables real-time data transfer to an online site.

The continuous costs of data transfer, electricity, sampling material or sample anaysis were not included in this estimate.

Operation Notes
These opetarional costs cover the annual costs for energy, data transfer, and sample analysis.
The hydrological probes on the sites save data with one minute interval and composite samples are collected weekly.
