Carbon dioxide levels are rising across wide swaths of the Arctic Ocean's Canada Basin（图）
Carbon dioxide levels rising across wide swaths Arctic Ocean Canada Basin
2020/7/10
Melting of Arctic ice caused by climate change has exposed more sea surface to the atmosphere. Scientists have long suspected this trend would increase carbon dioxide in Arctic Ocean waters.Now U...
Arctic snow not darkening due to soot,dust,Dartmouth-led study finds
Arctic snow soot dust Dartmouth-led
2015/11/12
For millennia, Greenland's ice sheet reflected sunlight back into space, but satellite measurements in recent years suggest the bright surface is darkening, causing solar heat to be absorbed and surfa...
Evaluation of stratospheric chlorine chemistry for the Arctic spring 2005 using modelled and measured OClO column densities
stratospheric chlorine chemistry the Arctic spring 2005 OClO column densities
2011/2/24
Chlorine dioxide, OClO, column amounts retrieved from measurements of the SCIAMACHY satellite instrument are presented and validated by comparison with simultaneous ground-based DOAS observations. In ...
Absorption of radiation by ice is extremely weak at visible and near-ultraviolet wavelengths, so small amounts of light-absorbing impurities in snow can dominate the absorption of solar radiation at t...
Sources of light-absorbing aerosol in arctic snow and their seasonal variation
light-absorbing aerosol arctic snow seasonal variation
2010/11/30
Two data sets consisting of measurements of light absorbing aerosols (LAA) in arctic snow together with suites of other corresponding chemical constituents are presented; the first from Siberia, Green...
IASI carbon monoxide validation over the Arctic during POLARCAT spring and summer campaigns
IASI carbon monoxide the Arctic POLARCAT spring summer campaigns
2010/11/30
In this paper, we provide a detailed comparison between carbon monoxide (CO) data measured by the Infrared Atmospheric Sounding Interferometer (IASI)/MetOp and aircraft observations over the Arctic. T...
Dynamics of the Antarctic and Arctic mesosphere and lower thermosphere – Part 1: Mean winds
the Antarctic and Arctic mesosphere lower thermosphere Mean winds
2010/11/29
Zonal and meridional winds have been measured in the upper mesosphere and lower thermosphere at polar latitudes using two ground-based meteor radars. One radar is located at Rothera (68° S, 68° W) in ...
Ozone variability and halogen oxidation within the Arctic and sub-Arctic springtime boundary layer
Ozone variability halogen oxidation the Arctic and sub-Arctic springtime boundary layer
2010/11/3
The influence of halogen oxidation on the variabilities of ozone (O3) and volatile organic compounds (VOCs) within the Arctic and sub-Arctic atmospheric boundary layer was investigated using field mea...
Spatial, temporal, and vertical variability of polar stratospheric ozone loss in the Arctic winters 2004/2005–2009/2010
polar stratospheric ozone the Arctic winters
2010/10/21
The polar stratospheric ozone loss during the Arctic winters 2004/2005–2009/2010 is investigated by using high resolution simulations from the chemical transport model Mimosa-Chim and observations fro...
Arctic shipping emissions inventories and future scenarios
Arctic shipping emissions future scenarios
2010/10/21
This paper presents 5 km×5 km Arctic emissions inventories of important greenhouse gases, black carbon and other pollutants under existing and future (2050) scenarios that account for growth of shippi...
Long-term trends of black carbon and sulphate aerosol in the Arctic: changes in atmospheric transport and source region emissions
black carbon sulphate aerosol the Arctic atmospheric transport source region emissions
