Observed trends in sunshine duration over South America

International Journal of Climatology, 2011
AbstractIn this work, temporal series of monthly mean values of sunshine duration were studied in five climatic regions of South America. For this purpose, data from 237 meteorological stations throughout South America were taken into account in: Argentina (20), Bolivia (2), Brazil (190), Paraguay (11), Peru (3), and Uruguay (11).

On the variations of sunshine duration in Austria

Theoretical and Applied Climatology, 1992
The seasonal and annual duration of sunshine in Austria during the 30 year period 1960–1989 is analyzed and the trends during this time interval are mapped. It is shown that sunshine decreased in the northern and eastern parts of Austria. In the mountain regions only small changes can be seen but there is some evidence that in the high mountain regions

Solar radiation and sunshine duration in East Asia

Archives for Meteorology, Geophysics, and Bioclimatology Series B, 1981
The relationship between solar radiation and sunshine duration is studied for 132 stations in East Asia. Regression coefficientsa andb in the modified Angstrom formulaQ/Qa = a + b n/N are found to be systematically distributed in the area with low values ofa and high values ofb in the winter maximum/summer minimum regime ofQ/Qa andn/N, and high values ...
