Tree-ring cellulose d18O variability in pine and oak and its potential to reconstruct precipitation and relative humidity in central Japan
tree-ring cellulose d18O pine oak precipitation relative humidity central Japan
2017/4/10
Oxygen isotope ratios (d18O) of tree-ring cellulose in pine (Pinus densiflora) and oak (Quercus serrate and Quercus
variabilis) growing in central Japan from 1970 to 2011 share a common inter-annual ...
Influence of relative humidity and temperature on the production of pinonaldehyde and OH radicals from the ozonolysis of α-pinene
relative humidity and temperature pinonaldehyde and OH radicals α-pinene
2010/8/16
The ozonolysis of α-pinene has been investigated under dry and humid conditions in the temperature range of 243–303 K. The results provided new insight into the role of water and temperature in the de...

This paper uses radiosonde launches made by the UK Meteorological Office, from the British Isles, Gibraltar, St. Helena and the Falkland Islands between January 2002 and December 2006, to investigate ...
Organic particulate matter formation at varying relative humidity using surrogate secondary and primary organic compounds with activity corrections in the condensed phase obtained using a method based on the Wilson equation
Organic particulate matter formation surrogate secondary primary organic the Wilson equation
2010/8/13
Secondary organic aerosol (SOA) formation in the atmosphere is currently often modeled using a multiple lumped "two-product" (N·2p) approach. The N·2p approach neglects: 1) variation of activity coeff...
Effects of relative humidity on aerosol light scattering in the Arctic

2010/8/12
Aerosol particles experience hygroscopic growth in the ambient atmosphere. Their optical properties – especially the aerosol light scattering – are therefore strongly dependent on the ambient relative...

Measurement relative humidity dependent light scattering aerosols
2010/2/8
Relative humidity (RH) influences the water content of aerosol particles and therefore has an important impact on the particles' ability to scatter visible light. The RH dependence of the particle lig...
