The temporal and spatial variations of low frequency geomagnetic pulsations at polar cusp and cap latitudes
Geomagnetic pulsations Antartica
2015/10/8
Geomagnetic field measurements at two Antarctic stations are compared during two weeks in the local summer (January 1-15, 1992). Low frequency (0.6-6 mHz) pulsations are observed at each station near ...

F1-region,Esand spread-F tesla
2015/9/14
Knowledge of the ionospheric electron density distribution and its fluctuations is essential for predicting ionospheric characteristics for radio wave propagation and for other applications such as
s...
On the relationship between the geometrical control of scintillation indices and the data detrending problems observed at high latitudes
ionospheric scintillation GPS scintillation monitors scintillation indices
2015/9/2
The experimental estimate of radio waves scintillation, caused by plasma density irregularities in the ionosphere, is usually attempted by means of scintillation indices which are essentially standard...
Multi-Satellite and Sensor Derived Trends and Variation of Snow Water Equivalent on the High-Latitudes of the Northern Hemisphere
Arctic Snow Water Equivalent Multi-Satellite Microwave Trends and Variations
2013/3/7
Utilizing more than 30 years of satellite-microwave sensor derived snow water equivalent data on the high-latitudes of the northern hemisphere we investigate regional trends and variations relative to...
Starspots, spin-orbit misalignment, and active latitudes in the HAT-P-11 exoplanetary system
Starspots spin-orbit misalignment active latitudes
2011/10/9
We present the analysis of 4 months of Kepler photometry of the K4V star HAT-P-11, including 26 transits of its "super-Neptune" planet. The transit data exhibit numerous anomalies that we interpret as...
Variability of the nighttime OH layer and mesospheric ozone at high latitudes during northern winter: influence of meteorology
the nighttime OH layer mesospheric ozone northern winter meteorology
2010/11/29
Analyses of OH zonal means, recorded at boreal high latitudes by the Aura Microwave Limb Sounder (MLS) in winters of 2005–2009, have shown medium- (weeks) and short- (days) term variability of the nig...
Solar Cycle Variation of Interplanetary Coronal Mass Ejection Latitudes
Sun activity coronal mass ejections (CMEs)
2010/9/15
With the use of interplanetary coronal mass ejections (ICMEs) compiled by Richardson and Cane from 1996 to 2007 and the associated coronal mass ejections (CMEs) observed by the Large Angle and Spectro...
Ionospheric transients observed at mid-latitudes prior to earthquake activity in Central Italy
Ionospheric transients observed mid-latitudes prior earthquake activity Central Italy
2010/10/20
Ionograms from Rome (41.8N, 12.5E) and Sofia (42.4N, 23.2E) ionospheric stations during earthquake (EQ) activity with magnitude (M) between 5 and 6 in Central Italy are analyzed. It is found that seve...
The structure of convective rain cells at mid-latitudes
The structure of convective rain cells mid-latitudes
2010/1/27
Rain cells are structures which represent an important component of convective precipitation and a study of their properties represents a necessary step both towards improved stochastic models of smal...
A three-dimensional model study of methanesulphonic acid to non sea salt sulphate ratio at mid and high-southern latitudes
three-dimensional model methanesulphonic acid mid and high-southern latitudes
2009/12/31
The Antarctic and sub-Antarctic methanesulphonic acid (MSA) to non sea salt sulphate (nssSO4) ratio is simulated with the Laboratoire de Météorologie Dynamique Atmospheric General Circulation Model in...
Tropospheric ozone from IASI: comparison of different inversion algorithms and validation with ozone sondes in the northern middle latitudes
Tropospheric ozone IASI ozone sondes northern middle latitudes
2009/12/31
This paper presents a first statistical validation of tropospheric ozone products derived from measurements of the IASI satellite instrument. Since the end of 2006, IASI (Infrared Atmospheric Sounding...
Ocean Acidification at High Latitudes: The Bellwether
Acidification surface water aragonite underground water sea sea creatures the cold water coral sea urchins mollusks
2015/7/6
Owing to anthropogenic-induced acidification, surface waters of the high latitudes are projected to become persistently undersaturated with respect to aragonite as early as mid-century. Seasonal arago...
Stratospheric warming in Southern Hemisphere high latitudes since 1979
Stratospheric warming Southern Hemisphere high latitudes
2009/7/15
In the present study, we show evidence of significant stratospheric warming over Southern Hemisphere high latitudes and large portions of the Antarctic polar region in winter and spring seasons, with ...
