Abstract:
This publication series contains the accumulation measurements from stake farm Neumayer II on the Ekström Ice Shelf, Antarctica. The stake farm has been in operation since March 1992. It consists of 25 poles (balise), placed in a grid of 5 x 5 with a spacing of 10 m. Readings have been carried out in approx. weekly intervals by the overwintering staff. This time series is interpolated to monthly resolution to remove the influence of irregular measurements in time. The original data on the irregular time grid will also be provided in the bibliography doi:10.1594/PANGAEA.971649. The time series contains the monthly mean accumulation rates (in cm/day), weighted by the number of days, for which the accumulation rate of the irregular measurements has been valid. Additionally, the accumulation rate per month is provided, by multiplying the monthly mean accumulation rate per day with the number of days in the corresponding month. The cumulative accumulation is the cumulative sum of the accumulation rate per month.
