Abstract:

Comprehensive spectral, actimetric, and meteorological data, obtained during a period of high solar activity (1981 and 1988) in order to determine how the effect of solar emissions is transmitted to the troposphere, are studied. The ability of water vapor to transform reversibly from the free state into a bound state (association in clusters) under the action of microwave and, as auxiliary factors, ultraviolet and corpuscular radiations has been observed experimentally for the first time.
When water vapor molecules a bound state the spectral optical thickness in the visible, near-IR, and IR regions of the spectrum decreases, and cluster absorption bands appear and deepen in the regions 330-340 nm, 365, and 380-390 nm. In the region 330-340 nm the spectral thickness of the cluster absorption can exceed 1.0.
It is affirmed that the anomalous transmission is caused by clusters and is realized under the conditions determined by S.F.Rodionov.
