On correlating the relative sunshine duration with the state of the sky
Solar & Wind Technology, 1990Abstract The state of the sky defined in terms of the cloud cover has been correlated with bright sunshine duration using data from five meteorological stations in Bangladesh. The r.m.s. errors of computed sunshine duration using the correlation are 2 to 5% for these stations.

INSOLATION AS AN EMPIRICAL FUNCTION OF DAILY SUNSHINE DURATION
Monthly Weather Review, 1954Abstract Empirical relations between incident solar radiation received at the earth's surface and (1) percent of possible sunshine, (2) latitude, and (3) time of year are developed. These relations are combined into a graphical method for converting percent of possible sunshine into daily values of incident solar radiation for stations between ...

Correlating beam radiation with sunshine duration
Solar Energy, 1992For seven locations in north and central India, monthly averaged data of daily beam irradiation on a horizontal surface, I, have been correlated with bright sunshine duration, s, using the relation (I/I{sub o}) = b{sub o}(s/S{prime}) where I{sub o} is the monthly mean value of extraterrestrial irradiation over a day, S{prime} is the corresponding ...

Solar radiation and sunshine duration in East Asia
Archives for Meteorology, Geophysics, and Bioclimatology Series B, 1981The 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 ...
