Description In this contribution, active layer thermal regime is presented in relation to net radiation components, air temperature and surface albedo variation at the Petuniabukta (Billefjorden, Svalbard) from July to August 2013. We estimated surface albedo from single measurements of incoming and outgoing shortwave radiation under clear-sky conditions. We found that diurnal variability of incoming solar radiation was clearly apparent from the changes of active layer temperature up to depth of 30 cm. Additionally, multivariable regression analysis was applied in order to estimate ground temperatures at the individual depths, considering the effects of air temperature, incoming radiation and surface albedo as the independent variables.
