| 英文摘要: | Comparisons between climate models have found large differences in predictions for the albedo of forested regions with snow cover, leading to uncertainty in the strength of snow albedo feedbacks on climate change predicted by these models. To explore this uncertainty, three commonly used methods for calculating the albedo of vegetated surfaces are compared, taking observed snow and vegetation distributions as inputs. Surprisingly, all three methods produce similar results and compare reasonably well with observations over seasonally snow-covered regions of the Northern Hemisphere. It appears that some climate models use unrealistic parameter values, and snow albedo masking need not be as large a source of uncertainty as it is in current climate projections. Key Points Climate model comparisons have shown wide range in albedo of snow-covered forest Models of widely differing complexity can compare well with albedo observations Good land cover data required, and optimal model parameters depend on data used ©2013 The Authors.
