METHOD OF DETERMINATION OF SPACE-TIME DISCONTINUITY OF SNOW COVER UNDER CONDITIONS OF ITS NATURAL OCCURRENCE Russian patent published in 2015 - IPC G01W1/04 

FIELD: instrumentation.

SUBSTANCE: invention relates to methods of physical properties study, and in particular of the snow cover. Essence of the invention is as follows: method of determination of space-time discontinuity of the snow cover under conditions of its natural occurrence includes preliminary making of the bore to the underlaying surface, determination of the snow thickness stratigraphy, avalanche probe insertion in the snow cover in the direct vicinity of the bore wall, registration of the acoustic emission signal generated during its movement, each snow thickness assignment with the characteristic form and modulating frequency of the acoustic emission signal, further insertion of the avalanche probe in the specified point of the snow cover, and stratigraphy determination in this point by comparison of the registered in it acoustic emission signal with the signal received for the reference bore.

EFFECT: decreased labour costs for studies upon keeping of the measurements accuracy.
