Automatic detection of cloud-free skies became more and more important in recent years to evaluate and interpret surface radiation measurements in the context of the greatly debated solar dimming and brightening and to investigate possible changes of

Net radiation flux in correlation with surface energy budget, snowmelt, glacier ice balance, and forest or agricultural flux exchange investigations is measured in numerous field experiments. Instrument costs and energy consumption versus performance

In this paper mainly simulations for developing the fog sensor NebioSens are presented. After some basic principles of light barriers, alternating beam technology, and fog the first ideas of a mechanical construction for sensor housing are shown. The

[1] Previous research indicates that clear-sky downward solar radiation measured at the surface over China significantly decreased by about −8.6 W m−2 per decade during 1961–1989 and insignificantly increased during 1990–1999. Furthermore, so

[1] A multidecadal decrease in downward surface solar radiation (solar “dimming”) followed by a multidecadal increase in surface radiation (solar “brightening”) have been reported over Europe. The trends mainly occur under cloud-free skies, a

[1] Mainland Europe's temperature rise of about 1°C since the 1980s is considerably larger than expected from anthropogenic greenhouse warming. Here we analyse shortwave and longwave surface forcings measured in Switzerland and Northern Germany and

[1] Atmospheric water vapor and surface humidity strongly influence the radiation budget at the Earth's surface. Water vapor not only absorbs solar radiation in the atmosphere, but as the most important greenhouse gas it also largely absorbs terrestr

Europe's temperature increases considerably faster than the northern hemisphere average. Detailed month- by-month analyses show temperature and humidity changes for individual months that are similar for all Europe, indicating large- scale weather pa
