Data of sap flow, tree size, soil water conditions and meteorology from Finland
<h3>Overview</h3><p>This data set includes the records of stem size at breast height, sap flow, soil water conditions and meteorology of/near two Scots pine (<i>Pinus sylvestris</i>) trees (named 'Pentti' and 'Sylvi') at Hyytiälä, Finland (61.8°N, 24.3°E). The data have been used in Liu <i>et al.</i> <i>Carbon source and sink limitations on boreal trees' cambial growth: implications of a coupled stomatal and growth model</i> (submitted to <i>New Phytologist</i> in October 2023). The Data Collector (Che Liu, University of Helsinki) collected the original data from SmartSMEAR (https://smear.avaa.csc.fi/) and processed to the current format and temporal resolution.</p><h3>Meanings (and units) of the columns</h3><h4>Sheet "tree_stats" </h4><ul><li>DBH, diameter at breast height (cm)</li><li>Asw, sapwood area (m^2)</li><li>H, tree height (m)</li></ul><h4>Sheets "Pentti_30min" and "Sylvi_30min"</h4><ul><li>DOY, day of the year</li><li>RBH, change of radius of breast height (mm), measured using the point dendrometer (AX-5 Solartron Metrology) and with thermal expansion corrected.

Sap flow in Norway spruce trees during the growing season 2015
<p>Primary data on the sap flow of Norway spruce trees growing on the southern border of their range in 2015 are presented. Coordinates N55.834715, E48.829725. The measurements were carried out from May 14 to August 31 with the help of instruments EMS51А (EMS, Brno, CZ). Measurement interval 10 minutes. At the same time, meteorological<br> observations.</p>
BOREAS TE-07 Sap Flow Data
The BOREAS TE-07 team collected data sets in support of its efforts to characterize and interpret information on the sap flow of boreal vegetation. The heat pulse method was used to monitor sap flow and to estimate rates of transpiration from aspen, black spruce, and mixed wood forests at the SSA-OA, MIX, SSA-OBS, and Batoche sites in Saskatchewan, Canada. Measurements were made at the various sites from May to Oct 1994, May to Oct 1995, and Apr to Oct 1996. A scaling procedure was used to estimate canopy transpiration rates from the sap flow measurements.
BOREAS TE-11 Sap Flow Data
The BOREAS TE-11 team collected several data sets in support of its efforts to characterize and interpret information on the sap flow, gas exchange, and lichen photosynthesis of boreal vegetation and meteorological data of the area studied. This data set contains measurements of sap flow conducted at the SSA-OJP site in the growing seasons of 1993 and 1994.
