2010/8/12
The influence of varying levels of water mixing ratio, r, during the formation of secondary organic aerosol (SOA) from the ozonolysis of α-pinene on the SOA hygroscopicity and volatility was investiga...
Widening the gap between measurement and modelling of secondary organic aerosol properties?
gap measurement modelling secondary organic aerosol properties
2010/3/16
The link between measured sub-saturated hygroscopicity and cloud activation potential of secondary organic aerosol particles produced by the chamber photo-oxidation of α-pinene in the presence or abse...
Gap filling and noise reduction of unevenly sampled data by means of the Lomb-Scargle periodogram
Gap filling noise reduction Lomb-Scargle periodogram
2009/7/1
The Lomb-Scargle periodogram is widely used for the estimation of the power spectral density of unevenly sampled data. A small extension of the algorithm of the Lomb-Scargle periodogram permits the es...
Towards closing the gap between hygroscopic growth and activation for secondary organic aerosol – Part 2: Theoretical approaches
hygroscopic growth secondary organic aerosol Theoretical approaches
2009/6/22
We examine the hygroscopic properties of secondary organic aerosol particles generated through the reaction of α-pinene and ozone using a continuous flow reaction chamber. The water activity versus co...
Towards closing the gap between hygroscopic growth and activation for secondary organic aerosol: Part 1 – Evidence from measurements
hygroscopic growth secondary organic aerosol
2009/6/22
Secondary Organic Aerosols (SOA) studied in previous laboratory experiments generally showed only slight hygroscopic growth, but a much better activity as a CCN (Cloud Condensation Nucleus) than indic...
Distinct wind convergence patterns in the Mexico City basin due to the interaction of the gap winds with the synoptic flow
Distinct wind convergence Mexico City gap winds synoptic flow
2009/1/6
Mexico City lies in a high altitude basin where air quality and pollutant fate is strongly influenced by local winds. The combination of high terrain with weak synoptic forcing leads to weak and varia...
