2010/8/16
One of the major objectives of the Megacities Initiative: Local And Global Research Observations (MILAGRO-2006) campaign was to investigate the long-range transport of polluted Mexico City Metropolita...
Satellite observations of long range transport of a large BrO plume in the Arctic
Satellite observations a large BrO plume the Arctic
2010/8/16
In this study, BrO measurements from the satellite instrument GOME-2 are used together with model calculations with the dispersion model FLEXPART to study an arctic BrO event in March 2007, which coul...
Long range transport of mercury to the Arctic and across Canada
Long range transport mercury the Arctic Canada
2010/8/16
This study is the most extensive study to date on the transport of mercury to the Arctic. Moreover, it is the first such study to use a fully-coupled, online chemical transport model, Environment Cana...
Size distributions of dicarboxylic acids, ketoacids, α-dicarbonyls, sugars, WSOC, OC, EC and inorganic ions in atmospheric particles over Northern Japan: implication for long-range transport of Siberian biomass burning and East Asian polluted aerosols
atmospheric particles Northern Japan Siberian biomass burning and East Asian polluted aerosols
2010/8/13
To better understand the size-segregated chemical composition of aged organic aerosols in the western North Pacific rim, day- and night-time aerosol samples were collected in Sapporo, Japan during sum...

Aerosol Single Scattering Albedo retrieval in the UV range: an application to OMI satellite validation
Aerosol Single Scattering Albedo retrieval UV range OMI satellite validation
2010/2/1
The aerosol Single Scattering Albedo (SSA) and Absorbing Aerosol Optical Depth (AAOD) at 320.1 nm are derived at Rome site by the comparison between Brewer and modelled spectra. The UVSPEC radiative t...
The role of soil states in medium-range weather predictability
soil states medium-range weather predictability
2009/11/12
Current day operational ensemble weather prediction systems generally rely upon perturbed atmospheric initial states, thereby neglecting the eventual effect on the atmospheric evolution that uncertain...
Long range predictability of atmospheric flows
Long range predictability atmospheric flows
2009/11/12
In the light of recent advances in 2D turbulence, we investigate the long range predictability problem of atmospheric flows. Using 2D Euler equations, we show that the full nonlinearity acting on a la...
Composition of the TTL over Darwin: local mixing or long-range transport?
TTL Darwin long-range transport
2009/11/9
We present ozone and carbon monoxide measurements taken in Darwin, Australia, during the wet season of 2005/2006, to examine whether the composition of the Tropical Tropopause Layer (TTL) reflects tha...
Effect of regional precursor emission controls on long-range ozone transport – Part 1: Short-term changes in ozone air quality
regional precursor emission controls long-range ozone transport ozone air quality
2009/8/25
Observations and models demonstrate that ozone and its precursors can be transported between continents and across oceans. We model the influences of 10% reductions in anthropogenic nitrogen oxide (NO...
