Zusammenfassung |
Land-use activities affect Earth's energy balance not only via biogeochemical
emissions, but also through perturbations in surface albedo, the latter of
which is often excluded in impact assessment studies. In this short technical
note, we present and compare a simple model for estimating shortwave
radiative forcings at the top of Earth's atmosphere to a more sophisticated
8-stream radiative transfer model based on a discrete ordinate method.
Outcomes from monthly albedo change simulations for ten globally distributed
regions and a single year revealed that the simple model – based on a single
exogenously supplied meteorological variable – performed quite well, having
a sample correlation coefficient of 0.93 and a normalized root mean square
error of 7.2%. Simple models like the one presented here can offer an
attractive and efficient means for non-experts to begin including albedo
change considerations in climate impact assessment studies enveloping land
use activities. |
