Dependence of surface albedo on snow cover duration and other snow parameters in Estonia
Meteorologische Zeitschrift, 1995 The duration of snow cover, the state of surface, and the albedo in late winter to early spring are studied as climatic factors. A linear dependence of the surface albedo on the duration of snow cover has been found from the data recorded at Tartu ...

Water and carbon balances in a hemi-boreal forest
Forestry Studies, 2023 The carbon and water fluxes and their inter-relations are key aspects of ecosystem dynamics. In this study, regionalization was used in transferring parameters from the GR4J-Cemaneige model calibrated in Reola hydrographic basin to predict daily flows in

Changes in snow cover and surface albedo in Estonia during the last 100 years
Meteorologische Zeitschrift, 1995 The year-to-year changes of the snow cover and the albedo in late winter and early spring as climatic factors are studied. The dependence of the surface albedo on the duration of snow cover recorded at the Tartu Actinometric Station in 1953-1992 has been

Proxy-based reconstruction of erythemal UV doses over Estonia for 1955-2004
, 2006 . A proxy-based reconstruction of the erythemally-weighted UV doses for 1955-2004 has been performed for the Tartu-Toravere Meteorological Station (58°16' N, 26°28' E, 70 m a.s.l.) site. The pyrheliometer-measured daily sum of direct irradiance on partly

Changes in the spectral aerosol optical thickness in Estonia (1951–2004)
Estonian Journal of Ecology, 2007 Broadband solar radiation has been measured during several decades, but the history of spectral measurements is relatively short. Several models exist for the calculation of the spectral atmospheric aerosol thickness from broadband solar radiation data ...

Relationships between surface albedo and spring heat accumulation
, 1996 A correlation is found between the June warmth index and the March surface albedo at Tartu-Toravere Actinometric Station for the period 1953–1992. To investigate the relationships between surface albedo and spring heat accumulation over larger areas ...
