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...

Several flight demonstrations have taken place over the past few years to show how the Wide-Area Augmentation System (WAAS), currently under development for the Federal Aviation Administration, will i...
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...
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...
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...

A set of coupled ocean-atmosphere(-vegetation) simulations using state of the art climate models is now available for the Last Glacial Maximum (LGM) and the Mid-Holocene (MH) through the second phase ...
Marine diffusive boundary layers at high latitudes
Marine diffusive boundary layers high latitudes
2014/5/19
The thickness of marine diffusive boundary layers (DBLs) can be calculated from the friction velocity and the water density (a function of temperature and salinity). However, DBL thickness scales diff...
Timing applications of growth regulators to alter spring cereal development at high latitudes
chlormequat barley oats wheat plant growth regulators ethephon growth tillering plant height
2010/8/16
Plant growth regulators (PGRs) are commonly used in commercial farming to control lodging in cereals. PGRs have been shown to alter yield formation and plant stand structure, other than the straw leng...
