Mega-cloud from Canadian wildfires will help model impacts of nuclear war（图）
Mega-cloud Canadian wildfires model impacts nuclear war
2019/10/21
Extreme wildfires in British Columbia, Canada, pumped so much smoke into the upper atmosphere in August 2017 that an enormous cloud circled most of the Northern Hemisphere – a finding reported in the ...
Characterising aerosol transport into the Canadian High Arctic using aerosol mass spectrometry and Lagrangian modelling
aerosol transport the Canadian High Arctic aerosol mass spectrometry Lagrangian modelling
2010/11/30
We report the analysis of measurements made using an aerosol mass spectrometer (AMS; Aerodyne Research Inc.) that was installed in the Polar Environment Atmospheric Research Laboratory (PEARL) in summ...
A trajectory analysis of atmospheric transport of black carbon aerosols to Canadian high Arctic in winter and spring (1990–2005)
atmospheric transport black carbon aerosols Canadian high Arctic
2010/8/13
Black carbon (BC) particles accumulated in the Arctic troposphere and deposited on snow have been calculated to have significant effects on radiative forcing of the Arctic regional climate. Applying c...
Characterization of a large biogenic secondary organic aerosol event from eastern Canadian forests
a large biogenic secondary organic aerosol event eastern Canadian forests
2010/8/12
Measurements of aerosol composition, volatile organic compounds, and CO are used to determine biogenic secondary organic aerosol (SOA) concentrations at a rural site 70 km north of Toronto. These biog...
Past and future conditions for polar stratospheric cloud formation simulated by the Canadian Middle Atmosphere Model
Past and future conditions polar stratospheric cloud formation Canadian Middle Atmosphere Model
2009/3/12
We analyze here the polar stratospheric temperatures in an ensemble of three 150-year integrations of the Canadian Middle Atmosphere Model (CMAM), an interactive chemistry-climate model which simulate...
The radar system described here (CMOR) comprises a basic 5-element receiving system, co-located with a pulsed transmitter, specifically designed to observe meteor echoes and to determine their positio...
Black carbon ageing in the Canadian Centre for Climate modelling and analysis atmospheric general circulation model
Black carbon Canadian Centre atmospheric general circulation model
2009/2/12
Black carbon (BC) particles in the atmosphere have important impacts on climate. The amount of BC in the atmosphere must be carefully quantified to allow evaluation of the climate effects of this type...
Persistence and photochemical decay of springtime total ozone anomalies in the Canadian Middle Atmosphere Model
photochemical decay springtime ozone anomalies Canadian Middle Atmosphere Model
2008/11/28
The persistence and decay of springtime total ozone anomalies over the entire extratropics (midlatitudes plus polar regions) is analysed using results from the Canadian Middle Atmosphere Model (CMAM),...
Summertime stratospheric processes at northern mid-latitudes: comparisons between MANTRA balloon measurements and the Canadian Middle Atmosphere Model

2008/11/4
In this paper we report on a study conducted using the Middle Atmospheric Nitrogen TRend Assessment (MANTRA) balloon measurements of stratospheric constituents and temperature and the Canadian Middle ...
Intercomparison of UV-visible measurements of ozone and NO2 during the Canadian Arctic ACE validation campaigns: 2004–2006
UV-visible measurements ozone NO2 Canadian Arctic ACE
2008/11/3
The first three Canadian Arctic ACE validation campaigns were held during polar sunrise at Eureka, Nunavut, Canada (80° N, 86° W) from 2004 to 2006 in support of validation of the ACE (Atmospheric Che...
