This accumulation dataset was derived from interpolation of in situ point measurements, i.e. snow pits, ice cores and stake measurements. Passive microwave satellite data (firn emissivity) were used as a "forcing field" to control the interpolation. The original data were supplied at a resolution of 25 km. The data were, here, interpolated onto the 5 km grid using spline interpolation.

The unit of the data is meters in ice equivalent per year.
