Method for measuring density of snow for e.g. pure and applied snow research purpose in modern weather station, involves measuring light attenuation between photoemitters and photodetectors to determine density of snow

NOVELTY - The method involves placing the snow on photoemitters (El-En) which emit light within the visible range towards corresponding photodetectors (Rl-Rn) located in the snow at a predetermined distance from the photoemitters. The light attenuation between the photoemitters and the photodetectors is measured. The density of the snow between the photoemitters and the photodetectors is determined from attenuation readings. USE - Method for measuring characteristic e.g. density of snow for pure and applied snow research purpose in modern weather station and and hydrogeological studies on flow of water resulting from snow thawing. Can also be used in thermal transmission coefficient characteristic and temperature variation characteristic. ADVANTAGE - The light attenuation between the photoemitters and the photodetectors is measured, so that the dynamic characteristics of the snow can be easily obtained at different depth even at snow fall. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for device for measuring characteristics of snow. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of device for measuring density of snow. Photoemitters (El-En) Milling (F1,F2) Poles (P1,P2) Photodetectors (Rl-Rn)
