Short summary

Before GRACE in 2002, few large-scale measurements of mass change over Greenland and Antarctica existed. We use a least squares inversion of satellite laser ranging (SLR) data to expand the polar mass change time series back to 1994. We explain the technique and analyze its errors, then apply it to SLR and GRACE data. We can estimate the summed mass change over Greenland and Antarctica with low uncertainty. SLR's noise causes interannual errors, but the 20-year estimate is reliable.
