According to the results of lidar observations carried out in June 2009 in Kamchatka, a very rear phenomenon,
noctilucent clouds, was observed during a week from June 17 to 23 at the heights of 80-85 km. Simultaneously
with that “Aura” satellite registered temperature decrease at this heights up to about 140oK on June 17. We
describe the method of correction of lidar signals to remove the eﬀects of the applied photoelectronic multiplier
which allowed to reform the proﬁles of the scattering ration up to the heights of 85-90 km.
