Temporal variability of accumulation at Neumayer station, Antarctica, from stake array measurements and a regional atmospheric model
In this study we investigate the ability of the Regional Atmospheric Climate MOdel (RACMO) to represent temporal variations of Antarctic accumulation using weekly stake array measurements from Neumayer Station. The model uses European Centre for Medium-RangeWeather Forecasts re-analysis data to forc...
