The global middle-atmosphere aerosol model MAECHAM5-SAM2: comparison with satellite and in-situ observations
global middle-atmosphere aerosol model ECHAM5-SAM 2 comparison with satellite in-situ observations
2014/12/9
In this paper we investigate results from a three-dimensional middle-atmosphere aerosol-climate model which has been developed to study the evolution of stratospheric aerosols. Here we focus on the st...
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 H Lyman-a actinic flux in the middle atmosphere
H Lyman-a actinic flux middle atmosphere
2009/3/10
The penetration of solar H Lyman-a radiation into the terrestrial middle atmosphere is studied in detail. The Lyman-a actinic flux is calculated with a Monte Carlo approach including multiple resonanc...
Simultaneous lidar observations of temperatures and waves in the polar middle atmosphere on the east and west side of the Scandinavian mountains: a case study on 19/20 January 2003
Simultaneous lidar polar middle atmosphere Scandinavian mountains
2009/2/26
Atmospheric gravity waves have been the subject of intense research for several decades because of their extensive effects on the atmospheric circulation and the temperature structure. The U. Bonn lid...
Middle atmosphere water vapour and dynamical features in aircraft measurements and ECMWF analyses
Middle atmosphere water vapour dynamical features aircraft measurement ECMWF
2008/12/23
The European Centre for Medium-Range Weather Forecasts (ECMWF) provides global analyses of atmospheric humidity from the ground to the lower mesosphere. Unlike in the troposphere, in the stratosphere ...
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),...
Reconstruction of the solar spectral UV irradiance for nowcasting of the middle atmosphere state on the basis of LYRA measurements
solar spectral UV middle atmosphere state LYRA
2008/11/10
The LYRA instrument onboard ESA PROBA2 satellite will provide 6-hourly solar irradiance at the Lyman-alpha (121.6 nm) and the Herzberg continuum (~200–220 nm wavelength range). Because the nowcasting ...
Summertime stratospheric processes at northern mid-latitudes: comparisons between MANTRA balloon measurements and the Canadian Middle Atmosphere Model
northern mid-latitudes MANTRA balloon 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 ...
Model simulation of the global circulation in the middle atmosphere for January conditions
global circulation January conditions atmosphere Polar Geophysical Institute
2010/1/28
A mathematical model of the global neutral wind system of the Earth's atmosphere, developed earlier in the Polar Geophysical Institute (PGI), is utilized to simulate the large-scale global circulation...
