Spatiotemporal mass balance trends for the Antarctic Ice Sheet, 2003-2013

The Antarctic mass trends have been collated from a combination
of different remote sensing datasets. These are trends of yearly
elevation changes over Antarctica for the period 2003-2013 due to
the different geophysical processes driving changes in Antarctica:
ice dynamics, surface mass balance and glacio-isostatic adjustment (GIA).
Net trends can be easily calculated by adding together surface and
ice dynamics trends.

20 km gridded datasets have been produced for each process, per year
(except the GIA solution which is time-invariant).

To convert elevation to mass trends, we also provide the density fields
for surface (SMB) and GIA processes used in Martin-Espanol et al (2016).

These can be directly multiplied by the dh/dt. To convert dh/dt from ice
dynamics, simply multiply by the density of ice.

Mass smb = dh/dt smb * d surf
Mass ice = dh/dt ice * d ice (not provided)
Mass gia = dh/dt gia * d rock
