Measuring the parameters of the atmospheric circuit with hourly and daily time resolution … is difficult to achieve and demonstrate. However, a relationship between Vi, the ionosphere- … to-ground potential difference, and Ez, the near-ground-level vertical electric field…
The Network for the Detection of Mesopause Change (NDMC) is a global program with the mission … to promote international cooperation among research groups investigating the mesopause … region (80-100 km) with the goal of early identification of changing climate signals.
The Network for the Detection of Mesopause Change (NDMC) is a global program with the mission … to promote international cooperation among research groups investigating the mesopause … region (80-100 km) with the goal of early identification of changing climate signals.
From September 01 to October 31, 2009, the first global NDMC measurement campaign has … been conducted. Several of the globally distributed NDMC stations provided rotational temperature … data derived from ground-based measurements of the OH and O2 emissions…
Aerogeophysical data obtained by the ICECAP project yield new insights into the basal … topography and evidence of new subglacial lakes within the Aurora Subglacial Basin, East … Antarctica. The new bed elevation map allows us to consider the flow paths of subglacial water.
The Aurora and Wilkes Subglacial Basins are major features of East Antarctica, containing significant regions below sea level. Before the International Polar Year (2007-9), the … extent and geology of the basins were poorly constrained by geophysical data. The IPY project…
Comparison of ice core records from Law Dome, East Antarctica and meteorological records shows … that periods of strengthened atmospheric zonal wave three (ZW3) circulation drive enhanced … meridional transport of moisture and tend to produce higher snowfall at Law Dome.
OH-equivalent temperatures derived from measurements made by the SABER instrument on board the TIMED satellite and the MLS instrument on board the Aura satellite are compared with rotational temperatures derived from OH(6-2)…
The southwest corner of Western Australia has been subject to a serious drought in recent decades. A range of factors, such … as natural variability and changes in land use, ocean temperatures and atmospheric circulation, have been implicated in this … drought…
The diet of Antarctic krill (Euphausia superba) has … been studied using a variety of techniques, but … current methods still suffer from problems that are … difficult to solve. This study examined an alternative … approach utilizing DNA as a prey biomarker.
Space weather forecasting is a very important tool for the space situational awareness to the space objects, the space environment and related threats and risks for manned and non-manned spacecrafts. The global network of ground based multi-directional detectors (GMDN)…
We use complementary observations from the prototype Global Muon Detector Network (GMDN) and the Advanced Composition Explorer satellite to identify precursors of geomagnetic storm events. The GMDN was completed in March 2006 with the installation of the Kuwait detector…
Ice cores from coastal East Antarctica provide highly resolved records that capture seasonal variations … in a wide range of climate proxies.
During the transition from the last glacial maximum to the present warm interglacial a sequence of large, hemispheric, climate changes took place: the Bølling‐Allerød and Younger … Dryas in the north and the Antarctic Cold Reversal in the south.
We compare thermal tropopause climatology in Arctic and Antarctic by NCEP–NCAR Reanalysis-1 data over the 1979–2008 period. The role of the troposphere and stratosphere in tropopause anomaly distribution is examined using corresponding temperature and geopotential height field.
