Global mercury emissions to the atmosphere from anthropogenic and natural sources
Global mercury anthropogenic natural sources
2010/8/13
This paper provides an up-to-date assessment of global mercury emissions from anthropogenic and natural sources. On an annual basis, natural sources account for 5207 Mg of mercury released to the glob...
Accelerating growth of HFC-227ea (1,1,1,2,3,3,3-heptafluoropropane) in the atmosphere
HFC-227ea the atmosphere
2010/8/13
We report the first measurements of 1,1,1,2,3,3,3-heptafluoropropane (HFC-227ea), a substitute for ozone depleting compounds, in air samples originating from remote regions of the atmosphere and prese...
Perfluorocarbons in the global atmosphere: tetrafluoromethane, hexafluoroethane, and octafluoropropane
the global atmosphere tetrafluoromethane hexafluoroethane octafluoropropane
2010/8/13
We present atmospheric baseline growth rates from the 1970s to the present for the long-lived, strongly infrared-absorbing perfluorocarbons (PFCs) tetrafluoromethane (CF4), hexafluoroethane (C2F6), an...
Dry and Wet Depositions of Polychlorinated Dibenzo-p-dioxins and Dibenzofurans in the Atmosphere in Taiwan
PCDD/Fs Dry deposition Wet deposition Fluxes Atmosphere
2016/3/29
The study has investigated the annual variation of the dry and wet depositions of polychlorinated dibenzo-p-dioxins and
dibenzofurans (PCDD/Fs) among different kinds of areas. A commercial suburban a...
Lidar characterization of the Arctic atmosphere during ASTAR 2007: four cases studies of boundary layer, mixed-phase and multi-layer clouds
Lidar characterization the Arctic atmosphere ASTAR 2007 boundary layer mixed-phase multi-layer clouds
2010/8/12
During the Arctic Study of Tropospheric Aerosol, Clouds and Radiation (ASTAR), which was conducted in Svalbard in March and April 2007, tropospheric Arctic clouds were observed with two ground-based b...
Oldest Measurement of Earth's Magnetic Field Reveals Battle Between Sun and Earth for Our Atmosphere（图）
Sun and Earth Our Atmosphere Earth's Magnetic Field
2010/3/23
Scientists at the University of Rochester have discovered that the Earth's magnetic field 3.5 billion years ago was only half as strong as it is today, and that this weakness, coupled with a strong wi...
Estimations of climate sensitivity based on top-of-atmosphere radiation imbalance
climate sensitivity top-of-atmosphere radiation imbalance
2010/2/21
Large climate feedback uncertainties limit the accuracy in predicting the response of the Earth's climate to the increase of CO2 concentration within the atmosphere. This study explores a potential to...
Metal concentrations in the upper atmosphere during meteor showers
Metal concentrations upper atmosphere meteor showers
2010/2/21
Using the nadir-viewing Global Ozone Measuring Experiment (GOME) UV/VIS spectrometer on the ERS-2 satellite, we investigate short term variations in the vertical magnesium column densities in the atmo...
Peroxyacetic acid in urban and rural atmosphere: concentration, feedback on PAN-NOx cycle and implication on radical chemistry
Peroxyacetic acid rural atmosphere PAN-NOx cycle radical chemistry
2010/2/1
Peroxyacetic acid (PAA) is one of the most important atmospheric organic peroxides, which have received increasing attention for their potential contribution to the oxidation capacity of the troposphe...
Different characteristics of char and soot in the atmosphere and their ratio as an indicator for source identification in Xi'an, China
atmosphere indicator source identification Xi'an China
2010/2/1
Numerous definitions and analytical techniques for elemental (or black) carbon (EC) have been published in the scientific literature, but still no generally accepted interdisciplinary definition exist...
Technical Note: Ensuring consistent, global measurements of very short-lived halocarbon gases in the ocean and atmosphere
Ensuring consistent very short-lived halocarbon gases ocean atmosphere
2010/2/1
Very short-lived halocarbons are significant sources of reactive halogen in the marine boundary layer, and likely in the upper troposphere and lower stratosphere. Quantifying ambient concentrations in...
Bacteria in the global atmosphere – Part 1: Review and synthesis of literature data for different ecosystems
Bacteria global atmosphere literature data
2009/12/31
Bacteria are ubiquitous in the atmosphere, with concentrations of bacterial cells typically exceeding 1×104 m−3 over land. Numerous studies have suggested that the presence of bacteria in the at...
Progress in understanding land-surface-atmosphere coupling over the Amazon: a review
