Investigation of atmospheric water vapour content in the Crimea by many-year solar observations
A method of water vapour content determination by measuring solar radiation absorption in the water vapour absorption band ρ is described. For the investigations an automatic solar photometer allowing to record solar radiation in the band ρ and neighbouring spectrum sections free of absorption has been applied. Regular observations (monitoring) have been performed in the Crimea (Simferopol, 44.7 N, 34.1 E) since 2001 till now. According to the results of the analysis water vapour content W in the atmosphere of the Crimea proved to be seasonably dependent, the average annual value being almost constant.
