Total land water storage change over 2003–2013 estimated from a global mass budget approach
We estimate the total land water storage (LWS) change between 2003 and 2013 using a global water mass budget approach. Hereby we compare the ocean mass change (estimated from GRACE space gravimetry on the one hand, and from the satellite altimetry-based global mean sea level corrected for steric eff...

We estimate the total land water storage (LWS) change between 2003 and 2013 using a global water mass budget approach.

For glaciers and ice sheets, we use published estimates of ice mass trends based on various types of observations covering different time spans between 2003 and 2013. From the mass budget equation, we derive a net LWS trend over the study period. The mean trend amounts to +0.30 ± 0.18 mm yr ^−1 in sea level equivalent. This corresponds to a net decrease of −108 ± 64 km ^3 yr ^−1 in LWS over the 2003–2013 decade. We also estimate the rate of change in LWS and find no significant acceleration over the study period.
