Description of record:Surface accumulation obtained from the 10 bamboo stake measurements carried out during 2018 in connection with Specific Surface Area measurements at EastGRIP camp Greenland. The record gives the relative surface height change compared to 8th May 2018, DOY 128, in cm.Method:10 bamboo stakes (wooden sticks with less than 1 cm in diameter) were setup up on a line perpendicular to the prevailing wind, which was approximately West-Southwest. The bamboo stakes were separated by 10 meter each. The event's latitude and longitude describes position of stake 1. During the summer season May to August the height of the individual stakes would be measured every day. The measurements were carried out using a ruler. The estimated precision is less than 0.5 cm. The relative surface height change was obtained by averaging the height change of the 10 stakes.
