Solar irradiance models and measurements: a comparison in the 220 nm to 240 nm wavelength band
, 2011 Solar irradiance models that assume solar irradiance variations to be due to changes in the solar surface magnetic flux have been successfully used to reconstruct total solar irradiance on rotational as well as cyclical and secular time scales. Modelling

The source, quantity, and spatial distribution of interfacial water during glide-snow avalanche release: experimental evidence from field monitoring [PDF]
The CryosphereGlide-snow avalanches release at the soil–snow interface due to a loss friction which is suspected to be linked to interfacial water. Presently, the formation and distribution of the interfacial water are not well understood and glide-snow avalanches are

Physics of Skiing: The Ideal-Carving Equation and Its Applications
, 2003 Ideal carving occurs when a snowboarder or skier, equipped with a snowboard or carving skis, describes a perfect carved turn in which the edges of the ski alone, not the ski surface, describe the trajectory followed by the skier, without any slipping or ...

Studying interspecific population synchrony: current status and future perspectives
Ecography, EarlyView.Interspecific population synchrony, or co‐fluctuations in the population dynamics and demographic parameters of different species, is an important ecological phenomenon with major implications for the stability of communities and ecosystems. It is also central in the context of biodiversity loss, as interspecific synchrony can influence how ecological ...

Snow effects on brash ice and level ice growth
Journal of GlaciologyBrash ice formation and accumulation occur at a faster rate in ship channels, harbours and turning areas compared to the surrounding level ice. Accurate prediction of brash ice thickness plays an important role in addressing operational challenges and ...
