We used data from a field experiment
in Northern Sweden,
in which climate
change was
simulated with open top chambers to increase the
air and soil
temperature, and with addition of plant litter from willow and birch - shrubs.
Scatter plot of
simulated springtime Δαs / ΔTs values
in climate
change (ordinate) vs
simulated springtime Δαs / ΔTs values
in the seasonal cycle (abscissa)
in transient climate
change experiments with 17 AOGCMs used
in this report (Δαs and Ts are surface albedo and surface
air temperature, respectively).
