A Data Acquisition System for Snow-cover Measurement

　A data acquisition system for snow-cover measurement has been developed. Application of computers to the system has made it easier to observe snow-cover and snow-fall. This system consists of an outdoor measuring station and a host computer. The outdoor measuring station has a multi-channel A/D converter, a CPU, a 32KB RAM, a clock, a modem, a temperature sensor, a wind gauge and snow pressure pillows to detect the pressure of the convered snow. The host computer saves the transmitted data to a floppy disk and displays the saved data as graphic images and tables. Field tests were carried out at Sapporo, Japan during the period from December 12, 1985 to April 10, 1986. The obtained informations can be utilized for efficient removal of snow.
