SUEWS and Yasso Model Runs for Helsinki Street Tree Carbon Sequestration

Model runs and measurement data from a study on the carbon sequestration potential of street trees in Helsinki support the calibration of urban environmental models. The dataset includes gap-filled meteorological data from 2003-2016, soil water content measurements, and 30-year simulation outputs for Alnus and Tilia tree species. Researchers can analyze canopy photosynthesis, soil carbon decay rates across three soil types, and the long-term impact of urban forestry.

Use Cases

• Calibrating the SUEWS urban energy and water balance model using gap-filled meteorological data from Helsinki-Vantaa airport and Kumpula.
• Estimating soil carbon stock changes with the Yasso model using monthly decay rates for three soil types from 2002 to 2016.
• Comparing carbon sequestration potential between Alnus and Tilia tree species based on site-specific model runs and canopy photosynthesis data.
• Validating model predictions against field measurements of soil water content from two streets and sap flow data.
• Conducting long-term (30-year) simulations of carbon sequestration from leaves and pruned branches using the provided Lifetimerun data.

Strengths

• Includes multi-year meteorological data (2003-2016) from the SMEARIII station in Kumpula, providing a substantial temporal baseline.
• Contains model outputs for a 30-year simulation (Lifetimerun), allowing for analysis of long-term carbon sequestration trends.
• Provides data for two distinct tree species (Alnus and Tilia) and three soil types, enabling comparative studies.

Limitations

• The exact row count, column names, and total dataset size are not specified in any source, limiting precise assessment of data volume.
• Metadata completeness is low; the last update date and specific file formats beyond MATLAB and Fortran codes are unknown.
• Primary data files appear to be model code and outputs rather than raw, systematically structured observational datasets.

Collection Method

Data collection involved meteorological measurements from Helsinki-Vantaa airport and the Kumpula SMEARIII station, combined with model runs from the SUEWS and Yasso environmental models.

Time Range

2002 to 2016 for core model outputs, with a 30-year simulation extending the temporal scope.

Geography

Helsinki, Finland, specifically street tree plantings and the Kumpula and Helsinki-Vantaa airport measurement sites.
