| contents | We investigated time series of 17 Antarctic drainage basins from April 2002 until August 2016 using data from the satellite gravimetry mission GRACE, a multi-mission altimetry product, and products from regional climate and firn modeling. The model products are cumulated surface mass balance anomalies (cSMBA) derived from RACMO2 outputs and firn thickness change predicted by the firn densification model (FDM) IMAU-FDM. We simultaneously evaluated these data sets in a state-space model framework to separate time-variable contributions from ice-dynamics and climatological forcing to mass and volume changes of the drainage systems. We parametrize long-term changes by a trend with a time-variable rate. Further we separate residual cyclic, first-order auto regressive (AR(1)), and irregular short-term variations. For each drainage basin we provide a file that includes mass and volume time series of the input data sets and the estimated signals along with their uncertainty (single standard deviation). The basin numbers refer to drainage systems defined by Zwally et al. (2012). |
