Aerosol fluxes and dynamics within and above a tropical rainforest in South-East Asia
Aerosol fluxes and dynamics a tropical rainforest South-East Asia
2010/10/11
Atmospheric aerosol measurements were conducted near Danum Valley, in the Malaysian state of Sabah, North-East Borneo, as part of the OP3 and ACES projects, in April and June/July 2008. Here, aerosol ...
On the impacts of phytoplankton-derived organic matter on the properties of the primary marine aerosol – Part 1: Source fluxes
phytoplankton-derived organic matter the primary marine aerosol Source fluxes
2010/10/11
A novel sub-micrometric size-resolved source flux function, explicitly defined as a function of the diatomaceous exudate concentration, was derived from the size distribution measurements and the esti...
Fluxes and concentrations of volatile organic compounds from a South-East Asian tropical rainforest

2010/9/21
As part of the OP3 field study of rainforest atmospheric chemistry, above-canopy fluxes of isoprene, monoterpenes and oxygenated volatile organic compounds were made by virtual disjunct eddy covarianc...
During two field campaigns (OP3 and ACES), which ran in Borneo in 2008, we measured large emissions of estragole (methyl chavicol; IUPAC systematic name 1-allyl-4-methoxybenzene; CAS number 140-67-0) ...
A comparison of dry and wet season aerosol number fluxes over the Amazon rain forest
dry and wet season aerosol number the Amazon rain forest
2010/8/12
Vertical number fluxes of aerosol particles and vertical fluxes of CO2 were measured with the eddy covariance method at the top of a 53 m high tower in the Amazon rain forest as part of the LBA (The L...
Linking urban aerosol fluxes in street canyons to larger scale emissions

Number fluxes of particles with diameter larger than 10 nm were measured with the eddy covariance method over the Amazon rain forest during the wet season as part of the LBA (The Large Scale Biosphere...
Surface fluxes and tropical intraseasonal variability: a reassessment
Surface fluxes tropical intraseasonal variability
2009/12/2
The authors argue for the hypothesis that interactive feedbacks involving surface enthalpy fluxes, both turbulent and radiative, are important to the dynamics of tropical intraseasonal variability. ...
Scale-dependency of surface fluxes in an atmospheric mesoscale model:effect of spatial heterogeneity in atmospheric conditions
Scale-dependency surface fluxes atmospheric mesoscale model spatial heterogeneity
2009/11/2
We examined the nonlinear effect of spatial heterogeneity in atmospheric conditions on the simulation of surface fluxes in the mesoscale model, MM5 by testing their scale-invariance from a tower footp...
