SMEAR II Siikaneva 1: Wetland Meteorology and Soil Data from Finland, 2005–2021

SMEAR II Siikaneva 1 contains time series of meteorology, solar and terrestrial radiation, ground heat flux, peat temperature, moisture, and water table depth measured at a fen site in Ruovesi, Finland. The data covers the years 2005 to 2021 and was exported from the SMEAR database by Pavel Alekseychik of the University of Helsinki. The most recent version of the data is available from the SMEAR platform.

Use Cases

• Modeling peatland carbon fluxes based on long-term meteorological and soil moisture time series.
• Analyzing the relationship between water table depth and ground heat flux in a fen ecosystem.
• Studying long-term trends in solar and terrestrial radiation within a boreal wetland.
• Calibrating hydrological models using peat temperature and moisture profiles.

Strengths

• Data spans a 17-year period from 2005 to 2021, enabling long-term trend analysis.
• Includes multiple coordinated physical measurements (meteorology, radiation, soil parameters) from a single site.
• Data originates from the authoritative SMEAR (Station for Measuring Ecosystem-Atmosphere Relations) database.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale ML tasks.
• Last update date is unknown; freshness unverified.
