Leaf-level gas exchange of Salix arctica in various plots representing high snow deposition and ambient snow in response to a snow fence. Snow fence was installed in 2003, gas exchange measured in 2012. Deep snow plots had approximately 74 cm of snow covering them. Ambient snow plots were 23 cm deep. LiCor 6400 w/ 2-cm2 fluorometer chamber. Samples were collected six days during 2012. Measurement parameters were: light 1250 umol m-2 s-1, 400 ul l-1 CO2 in chamber. Measurements made approximately 2 hours either side of solar noon. .csv, comma-delimited text. Data are standard output from 6400 with the addition of day of year, a plot identifier, and a rep identifier. Plots 1-3 are +snow, plots 4-6 are ambient snow.
