Forests will also influence other biophysical properties of climate relevance, such as surface roughness affecting convective heat transfer and the amount of water recycled to the atmosphere by evapotranspiration. These biophysical factors may strengthen or weaken the albedo effect, depending on the particular system properties. In boreal regions, snow-covered fields or tundra may have albedos approaching 0.6-0.8, compared to only 0.2-0.3 for evergreen conifer forest during winter and around 0.1 during summer (Anderson et al. Actual albedo values will depend on specific ecosystem and climate factors like the angle of incoming radiation, clouds, terrain, and snow conditions.
