There exist several results of mass balance of the Antarctic Ice Sheet (AIS) estimated based the laser altimetry ICESat. especially for some with a significant difference. In this study. we attempt to use the ICESat data to re-estimate the mass balance of the AIS over 2003-2008 by making several systematic improvements in data processing and model construction. https://www.duospiritalis.com/top-deal-Serra-Avatar-Urza-s-Saga-clearance/
