This shapefile contains the spatial zonation for ICESat-derived glacier surface elevation change rates for 2003-2008, as well as a conversion to volume (mass) changes. 

Attribute table description and units
-------------------------------------

unit_name	unit label referred to in the text
geography	corresponding mountain region
RGIglarea	total glacier area within spatial unit, in square kilometres, derived from RGI 6
dhdt		glacier surface elevation change rate, in metres per year
dhdt_err	total error* of dhdt (1 sigma), in metres per year
dhdt_snowc**	glacier surface elevation change rate, after correcting December 2008 samples for snow cover
dhdt_s_err**	total error* of dhdt_snowc (1 sigma), in metres per year
Gtdt		glacier mass change, using RGIglarea and a density of 850 kg/m3, in Gt per year
Gtdt_err	total error* of Gtdt (1 sigma), in Gt per year


* total error includes: error of dhdt (from linear fit),  difference to surface elevation change rate using the "standard method", off-glacier surface elevation change trend, difference to surface elevation change rate after correcting December 2008 samples for snow cover. 

** null values for spatial units where the December 2008 snow correction could not be computed due to lack of off-glacier samples
