7Be in Finland during the 1999-2001 Solar maximum and 2007-2009 Solar minimum

► The solar modulation effect was not observed in 7Be air concentrations or in deposition. ► A 45-90-day intraseasonal oscillation was found in the surface air 7Be concentrations. ► 7Be deposition velocities were found to be less compared to mid-latitude ones. ► First quantitative analysis of regional and temporal variation of 7Be deposition in Finland.
