S. B. Luthcke et al., 2009 Fall AGU, Greenland ice sheet (GrIS) mass changes (through July 25, 2009) from NASA/GSFC GRACE Mascon solutions


Greenland Ice Sheet Mass Changes from NASA GSFC GRACE Mascon Solutions

∗S. B. Luthcke, D. D. Rowlands, J. J. McCarthy, A. Arendt, T. Sabaka, J. P. Boy, F. G. Lemoine, "Recent Changes of the Earth's Land Ice from GRACE," presented at 2009 Fall AGU, H13G-02 (693337), Dec. 14, 2009.

The mass changes of the Greenland Ice Sheet (GrIS) are computed from the Gravity Recovery and Climate Experiment (GRACE) inter-satellite range-rate observations for the period April 5, 2003, through July 25, 2009. The mass of the GrIS has been computed at 10-day intervals and 200-km spatial resolution from a regional high-resolution mascon solution (Luthcke and others, 2008 and 2006). The animation shows the change in mass referenced from April 5, 2003. The spatial variation in surface mass is shown in centimeters equivalent height of water. The time variation of the GrIS mass is shown in the x-y plot insert with units of gigatons.
