| Zusammenfassung |
| We investigate the suitability of ELPI for condensation sink and ion sink
measurements. The aim is to find the simple calibration factors by which the
measured ELPI current can be converted to condensation or ion sinks. The
calibration is based on DMPS and ELPI measurements within the period 15–25 May 2005
at a boreal forest site in Southern Finland. The values
of condensation sink and ion sink were calculated from the DMPS size
distributions using their theoretical definitions. After that the values were
compared to theoretical and measured ELPI current, and calibration factors
were specified. For condensation sink the calibration factor was found to be
7.27E-06 s−1 fA−1 and for ion sink 8.55E-06
s−1 fA−1. Simply by multiplying the total current of the
outdoor ELPI by these factors, the values of condensation sink and ion sink
can be measured. |
