Aerospace Instrument-Making Annotation << Back THE NEW METHOD FOR MEASUREMENTS OF SOLAR CONSTANT USING TWO-WAVELENGTH PHOTOMETER H.H. Asadov, I.Kh. Agayev The new two-wavelengths method for measuring of solar constant using sun photometers has been suggested. It is shown, that differ from the known method the measurements at the fixed wavelength should be carried out at only one value of optical air mass which makes it possible to get the two-fold advantage in amount of number of needed measure-ments. Key words: solar constant, photometer, optical air mass. E-mail: asadzade@rambler.ru
