Abstract

Midges contribution estimates to extinction of optical radiation for background conditions of summer of Western Siberia are received. The midges represent live organisms the sizes some millimeters, and include a gnat, a midge, a wood louse, a mosquito and a gadfly. From July 24 to August 13, 2014 the coefficient extinction of midges changed from 0 to 0.14 km^-1, and its average value made 0.065 km-1. The daily course extinction coefficient of midges of has the pronounced morning maximum falling on 8 hours and an indistinct evening minimum - for 19 hours. For the received data file, probability of difference of their average values at 8 and 19 hours by t-criterion of Student made 96%.
