Engineering Physics Annotation << Back On possibility of measuring of low aerosol loading of atmosphere using direct scattered radiation at low heights of the Sun I.Kh. Agayev, N.H. Javadov The three – wavelength method for measuring of low aerosol loading in condition of meaningful amount of scattered radiation providing for full compensation of scattered radiation is suggested. The quadratic equation is obtained, solution of which makes is possible to calculate the Angstrom turbidity factor in condition of low aerosol loading. Key words: Atmospheric, aerosol, photometer, scattered radiation. E-mail: аgayev-tekti@rambler.ru.
