Aerospace Instrument-Making Annotation << Back On correction of multi-wave sun photometers in condition of changing meteorological situation H.H. Asadov, D.Z. Aliyev, S.N. Abdullayeva In the article, the effect of relative humidity of atmosphere an accuracy of functioning of sum photometers is analyzed. The method for compensation of aerosol error upon given value of relative humidity is suggested. The aerosol error occurred due to changes of relative humidity. Key words: Sun photometer; multiwavelength measurements; aerosol; relative humidity. E-mail: asadzade@rambler.ru
