Snowboard (meteorology)
A snowboard (US) or weaverboard (Canada) is a meteorological tool used to aid in the obtaining of accurate measurement of snow accumulation. Specifications Snowboards are typically flat pieces of plywood painted a light color (most commonly white), around in length and width and around thick. In addition, the weaverboard used in Canada has a white stick with a black tip placed in the centre. This allows the board to be found if the newly fallen snow was to completely cover the board. Reasons for use When measuring snow in grass, the blades will produce inflated snow totals, whereas with a snowboard, this effect is absent. The light or white color of a snowboard serves to minimize heating by sunlight, which often occurs on paved surfaces. These qualities make snowfall measurement using a snowboard more accurate than measurements without one. Usage Snowboards should be placed at ground level at a distance away from a building of at least two times the height of that building. When measuring snowfall on a snowboard, the snowfall is measured to the nearest . The snow may be measured as often as necessary during a 6-hour period in order to record the greatest depth on the
