We study the scattering ratio profiles obtained from lidar station IKIR FEB RAS (Kamchatka) from 2007 to 2011, during the cold period October-March. Obtained average profiles in the mesosphere have maxima at heights of 65, 69, and 75 km. Negative correlations between the average scattering ratio and temperature in the mesosphere during a stratospheric warming, and in the stratosphere in the serene days are found.
