Abstract
Recent studies have demonstrated empirical relationships between surface soil moisture and the α′ parameter in Priestley and Taylor's version of the combination model. An evaporation study conducted at a high arctic site shows that for gravel and loamy surfaces underlain by permafrost, α′ can be expressed as the following function of soil moisture (Sm): Comparison with α′ and soil moisture relationships obtained in more temperate latitudes suggests that under drying conditions the evaporation rate will be a response to the particular site characteristics, so that there is no unique relationship between surface soil moisture and evaporation rates.Keywords
