This work presents an overview of the results obtained in
an analysis of the 7Be activity concentrations recorded in
surface air in Helsinki, Finland, over a 25-year period
(1987-2011), and stored in the online Radioactivity
Environmental Monitoring (REM) database.
First, lagged linear correlations of the 7Be specific
activity with several meteorological variables:
tropopause height (TPH); mean, minimum and
maximum temperature; precipitation (Prec); atmospheric
pressure (Press); potential vorticity (PV) at 300 hPa and
200 hPa; solar zenith angle (SZA); and sunspot number
are analysed (Tab. 1). The time lag in the correlation
calculations is allowed to vary between 0 and 7 days for
TPH, meteorological parameters and PV, and between 0
and 31 days for SZA and sunspot number. The
correlations are calculated for the total set of
measurements as well as for different seasons.
