... the approximation T C ≈ T L is fairly precise for most caves. Effects of snow Moving northwards, the effect of a continental climate on the precipitation season holds, but an important new phenomenon is seen and is discussed here for the case of Perm (Russia). The average temperature in Perm is +1.7°C...

... Abstract Snow albedo is an important climate parameter as it governs the amount of solar energy absorbed by the snow and can be considered a major contributor to the surface radiation budget. The present study deals with the estimation of temporal variation of snow albedo at the upper elevation...
