Environmental and gross primary production observations for a mature black spruce site located in central Saskatchewan, Canada

This record is for the dataset “Environmental and gross primary production observations for a mature black spruce site located in central Saskatchewan, Canada” at doi.org/10.20383/101.0300 Observations are presented here for the late winter / early summer period (March 20 to June 26) for 2019 and 2020 at a mature black spruce site located in central Saskatchewan, Canada. Daily means and standard deviations of the diurnal variability are reported for photosynthetically active radiation (PAR), soil volumetric water content (VWC), soil temperature, air temperature, vapour pressure deficit (VPD) and gross primary production (GPP).

The site is equipped with a walk-up scaffold tower, 25m in height. PAR was measured with a Li-COR LI190R installed at the top of the tower; air temperature and relative humidity were measured at 6m height with a Vaisala HMP45C probe housed in a 12-plate Gill radiation shield; soil temperature at 10 cm depth was measured at two locations with Type-T (copper-constantan) thermocouples and averaged; soil VWC at 7.5 cm depth was measured at two locations with Campbell Scientific CS615 probes and averaged; VPD was calculated from air temperature and relative humidity.
