SMEAR data preservation 2019

Abstract

This data publication was done for preservation of SMEAR data. It links together 12 published datasets that contain continuous long-term environmental measurements under different themes or fields of science (meteorology, soil, air chemistry, fluxes, tree ecophysiology, water quality). See the list of related datasets in the metadata and in the .pdf file of this dataset. The data were exported from SMEAR database in early June 2019 and cover time period from the beginning of the station operation or measurements until the end of 2017 or 2018 (if the station or measurements were still in operation at that time). The oldest data originate in year 1992. The data are so called end-user data, that is, they have undergone processing from raw signals into relevant physical units, quality check by expert scientists and technicians, and aggregation into regular time intervals, mostly 1-minute or 30-minute averages. Information on the stations, measurements and data can be found in each dataset in the 'intro' and 'readme' files in .pdf format. The data are in tabular form in yearly .csv files. The columns of the data files are described in more detail in 'VariableMetadata' files in .csv format.
