A snowboard is a meteorological tool used to aid in the obtaining of accurate measurement of snow accumulation. Contents 1 Specifications 2 Reasons for use 3 Usage 4 See also 5 References Specifications Snowboards are typically flat pieces of plywood painted a light color (most commonly white), around 16 to 24 inches (41 to 61 cm) in length and width and around 0.5 to 0.75 inch (13 to 19 mm) thick.[1][2][3][4] Reasons for use Measuring snow in grass the grass blades will produce inflated snow totals, whereas with a snowboard this effect is absent.[3] The light or white color of a snowboard serves to minimize heating by sunlight.[4] These qualities make snowfall measurement using a snowboard more accurate than measurements without one.[2][3][4] 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.[1] When measuring snowfall on a snowboard, the snowfall is measured to the nearest 0.1 inches (2.5 mm)[1] and is measured no more than four times in a 24 hour period (once every six hours).[4] After a measurement is taken, all snow is cleaned off of the snowboard.[3][4] At the end of the snow event, the measurements taken each time the snowboard was cleaned are added together to produce the storm total snowfall.[4] See also Snow gauge Snow pillow Rain gauge References ^ a b c "Things to know about snow".
