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…
Using the Davis (68°S, 78°E) lidar, several observing campaigns recently examined the small scale temperature structure and variability in the Antarctic winter upper troposphere and lower stratosphere (UTLS). Lidar measurements of N2 Raman backscatter were obtained over the altitude range of 8…
We analyse the precursor of a Forbush decrease (FD) observed with the Global Muon Detector Network on 2006 December 14. An intense geomagnetic storm was also recorded during this FD with the peak Kp index of 8+.
We evaluate atmospheric ionization during the Ground Level Enhancement (GLE) of 2005 Jan 20 using the continuous slowing down (CSD) energy loss approximation [1,2]. The top-of-atmosphere particle flux is derived using satellite measurements (for particle energies below 500MeV)…
Schooling behaviour of Antarctic krill was induced repeatedly over a period of one year in the Australian … Antarctic Division research aquarium. The details of the laboratory setup suitable for krill to school are … described.
