Long range transport of ultra cold atoms in a far-detuned 1D optical lattice
Long range transport ultra cold atoms far-detuned 1D optical lattice Atomic Physics
2012/4/27
We present a novel method to transport ultra cold atoms in a focused optical lattice over macroscopic distances of many Rayleigh ranges. With this method ultra cold atoms were transported over 5 cm in...

Measurements of significant concentrations of IO, I2 and BrO in a semi-polluted coast environment at Roscoff, in North-West France, have been made as part of the Reactive Halogens in the Marine Bounda...
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...
Spectral optical properties of long-range transport Asian dust and pollution aerosols over Northeast Asia in 2007 and 2008
Spectral optical properties long-range transport Asian dust and pollution aerosols Northeast Asia 2007 and 2008
2010/8/13
As a part of the IGAC (International Global Atmospheric Chemistry) Mega-cities program, aerosol physical and optical properties were continuously measured from March 2007 to March 2008 at an urban sit...
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...
Injection in the lower stratosphere of biomass fire emissions followed by long-range transport: a MOZAIC case study
lower stratosphere biomass fire emissions MOZAIC
2009/8/18
This paper analyses a stratospheric injection by deep convection of biomass fire emissions over North America (Alaska, Yukon and Northwest Territories) on 24 June 2004 and its long-range transport ove...
Interannual variability of long-range transport as seen at the Mt. Bachelor observatory
Interannual variability long-range transport Mt. Bachelor observatory
2009/3/12
Interannual variations in background tropospheric trace gases (such as carbon monoxide, CO) are largely driven by variations in emissions (especially wildfires) and transport pathways. Understanding t...
