공공데이터포털
The BOREAS group TE-05 collected measurements in the NSA and SSA on gas exchange, gas composition and tree growth. Soil respiration data collected in the BOREAS NSA and SSA to compare the soil respiration rates in different forest sites using a Li-Cor 6200 soil respiration chamber (model 6299).
BOREAS TE-05 Leaf Carbon Isotope Data
공공데이터포털
The BOREAS group TE-05 collected measurements in the NSA and SSA on gas exchange, gas composition and tree growth. This documentation describes leaf carbon isotope data that were collected in 1993 and 1994 at the NSA and SSA OJP, OBS and NSA UBS sites. In addition, leaf carbon isotope data were collected in 1994 only at the NSA and SSA OA sites. These data were collected to provide seasonal integrated physiological information for 10 to 15 common species at these 6 BOREAS sites.

BOREAS TE-09 Photosynthetic Capacity and Foliage Nitrogen Data
공공데이터포털
The BOREAS TE-09 team collected several data sets related to chemical and photosynthetic properties of leaves in boreal forest tree species. This data set describes the spatial and temporal relationship between foliage nitrogen concentration and photosynthetic capacity in the canopies of black spruce, jack pine, and aspen. The data were collected from June to September 1994 and are useful for modeling the vertical distribution of carbon fixation for different forest types in the boreal forest.
BOREAS TE-05 Leaf Gas Exchange Data
공공데이터포털
The BOREAS group TE-05 collected measurements in the NSA and SSA on gas exchange, gas composition and tree growth. The leaf photosynthetic gas exchange data were collected in the BOREAS NSA and the SSA using a Li-Cor 6200 portable photosynthesis system. The data were collected to compare the photosynthetic capacity, stomatal conductance and leaf intercellular CO2 concentrations among the major tree species at the BOREAS sites. The data are average values from diurnal measurements on the upper canopy foliage (sun leaves).
BOREAS TE-10 Photosynthetic Response Data
공공데이터포털
The BOREAS TE-10 team collected several data sets in support of its efforts to characterize and interpret information on the gas exchange, reflectance, transmittance, chlorophyll content, carbon content, hydrogen content, nitrogen content, and photosynthetic response of boreal vegetation. This data set contains measurements of quantitative parameters and leaf photosynthetic response to increases in light conducted in the SSA during the growing seasons of 1994 and 1996 using an oxygen electrode system. Leaf photosynthetic responses were not collected in 1996.
