This ArcGIS shapefileset contains the results of the firn model UUFIRNMODELv2.1/ANT forced by climate data from RACMOv2.2/ANT27.The model was run for 100 sites, 99 of which are on Antarctic ice shelves, 1 on a grounded ice cap. The firn height change results given here were used to separate the components of the measured ice-shelf surface height-change signal that came from surface firn processes and ice-shelf basal processes respectively. The results presented here apply to the period: day 277 of 2003 to day 351 of 2008, spanning the ICESat campaigns 2A to 3K used in the study.Attribute Meaning- POINT_X Longitude (decimal degrees)- POINT_Y Latitude (decimal degrees)- VdB_Acc_mn Total accumulation (mm water equivalent)- VdB_Mlt_mn Total melt (mm water equivalent)- VdB_net_MA Total accumulation minus total melt (mm water equivalent)- FirnDHDTcm Net firn height change (cm) ...
