Statistical Investigations of Solar Radiation observed at some Home Stations by means of Silver-disk Pyrheliometers. (Preliminary Report)

[摘要] In this short report, are given the preliminary study of the results of observations of solar radiation made by means of silver-disk pyrheliometers at fifteen meteorological stations in Japan. Observations has been carried out three times on every clear day since August 1932, and only those results that are obtained from the observations when the sun's disk was free from clouds were used for present discussion. Computing the hourly and monthly mean values of the transmission coefficients, their distributions are investigated and, diurnal as well as seasonal variations compared with one another.
