title: Investigation of the Atmospheric WaterVapor Content in Crimea Via LongTerm Photometric Solar Observations
abstract: Watervapor content determination via solarra diation absorption measurement in the water� vapor absorption band ρ is described. The investigation was carried out with an automatic solar photometer, making it possible to record solar radiation in the band ρ and adjacent absorptionfree spectrum sections. Regular observations have been performed in Crimea (Simferopol, 44.7 N and 34.1 E) from 2001 to the present. According to the observation data, the watervapor content W in the atmosphere of Crimea
