resulted in devastating bushfires igniting in south-eastern Australia. As a result, a significant amount of smoke aerosols was injected into the upper troposphere-lower stratosphere (UTLS) region. Its properties, in particular H2O enhancement inside the smoke plume…
Changes in solar activity modulate the galactic cosmic ray flux, and in turn, the production rate of cosmogenic 10Be in the Earth’s atmosphere. The best archives of past changes in 10Be production rate are polar ice cores.
The Global Atmosphere Watch of WMO includes several stations in Antarctica that keep a close eye on the ozone … layer during the ozone hole season. Observations made during the ozone holes from 2003 to 2009 will be compared … to each other and interpreted in light of the meteorological conditions.
As part of the global project ORACLE-O3 selected for the IPY, LOLITA-PSC (“Lagrangian Observations with Lidar Investigations and Trajectories in Antarctica and Arctic, of PSC”) is devoted to Polar Stratospheric Clouds (PSCs) studies. Indeed…
Zonal asymmetry in quasi-stationary ozone distribution is considered in the latitude range 50-80S using satellite total ozone data. Amplitude of the quasi-stationary wave has been determined as a half-difference between maximal and minimal values in 3-month averaged ozone distribution. Besides…
