distribution in the area of Greet Tolbatchik
Volcano on the Kamchatka by means of flying laboratory IL-18 at wavelength

= 27 cm. This
map was reconstructed by means of the GIMS-technology basing on the trass data
reliability in most cases. It is connected with that main contribution to the micro-
wave emission by the
fire hotbed gives the
fl
flame particles having the sizes up to
100
m. The burning zone gives the radiobrightness temperature increase on
the wavelength 0.8 cm equaled about 200 K. It exceeds the radiometers sensitivity
limit. Therefore, microwave monitoring of forest

fires in contradiction to optical
methods does not depend on the weather conditions.
