Global distributions of methanol and formic acid retrieved for the first time from the IASI/MetOp thermal infrared sounder
formic acid the IASI/MetOp thermal infrared sounder
2011/2/24
Methanol (CH3OH) and formic acid (HCOOH) are among the most abundant volatile organic compounds present in the atmosphere. In this work, we derive the global distributions of these two organic species...
Assessing observed and modelled spatial distributions of ice water path using satellite data
observed and modelled spatial ice water path satellite data
2011/1/19
The climate models used in the IPCC AR4 show large differences in monthly mean ice water path (IWP). The most valuable source of information that can be used to potentially constrain the models is glo...
Polar organic marker compounds in atmospheric aerosols during the LBA-SMOCC 2002 biomass burning experiment in Rondônia, Brazil: sources and source processes, time series, diel variations and size distributions
Polar organic marker atmospheric aerosols the LBA-SMOCC 2002 biomass burning experiment time series diel variations size distributions
2010/10/11
Measurements of polar organic marker compounds were performed on aerosols that were collected at a pasture site in the Amazon basin (Rondônia, Brazil) using a high-volume dichotomous sampler (HV...
Particle size distributions from laboratory-scale biomass fires using fast response instruments
Particle size laboratory-scale biomass fires fast response instruments
2010/9/14
Particle size distribution from biomass combustion is an important parameter as it affects air quality, climate modelling and health effects. To date, particle size distributions reported from prior s...
The effect of reported high-velocity small raindrops on inferred drop size distributions and derived power laws
reported high-velocity small raindrops inferred drop size distributions derived power laws
2010/8/16
It has recently been shown that at high rainfall intensities, small raindrops may fall with much larger velocities than would be expected from their diameters. These were argued to be fragments of rec...

elemental carbon extinction urban and rural locations the pearl river delta region
2010/8/13
Elemental carbon (EC) in size-segregated aerosol samples were determined at five urban, one suburban, and one rural locations in the Pearl River Delta region in South China during 2006–2008 period. Th...
Particle number size distributions in urban air before and after volatilisation
Particle number size distributions urban air volatilisation
2010/8/13
Aerosol particle number size distributions (size range 0.003–10 μm) in the urban atmosphere of Augsburg (Germany) were examined with respect to the governing anthropogenic sources and meteorological f...
