After the war, since 1950 the measurements were continued at the Tartu Actinometric Station, located at the outskirts of the town (58.35[degrees]N, 26.68[degrees]E).
The model was used by Yarkho-Gorbarenko to analyse spatial and temporal variability of the AOT550 according to the broadband observations from 155 actinometric stations on the territory of the Soviet Union (Gorbarenko, 1997).
This well-equipped actinometric station is included into the Basic Surface Radiation Network (BSRN) where PW is an indispensable input in studies of radiation and aerosol regime (McArthur, 2005).
