...and now...
attaching the new 25m2 teflon bag to the flow reactor
Biogenic Secondary Organic Aerosols Workshop, August 11-15, 2008, Tovetorp Zoological Research Station, Sweden
Scientific interests and outlooks
Main focus: laboratory measurements of evaporation rates of aerosol particles
 vapor pressure
Of binary (organic/water) and ternary particles (organic/inorganic/water)
...and complementary smog chamber measurements
(Ozone/NO/NO2 monitors, SMPS)
...and CCN activity... (DMT/CCN and Wyoming type CCN counter)
Implementation of the results into microphysical models (BCOND-Helsinki)
...and from this workshop it would be nice to have somebody who asks me
to measure something…
