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

Methodology:
The data used a Bayesian Hierarchical Model driven by different remote sensing datasets: ICESat, Envisat, Cryosat-2, GRACE and a network of elastic-corrected GPS stations. The methodology is described in detail in the following papers: Zammit-Mangion et al (2014), Zammit-Mangion et al. (2015a), Zammit-Mangion et al. (2015b) and Martin-Espanol et al (2016).
Data collection:
Information about the processing of the different datasets can be found partially in Schoen et al. (2015) (not all data sets are used) and completely in Martin-Espanol et al (2016). Details on the architecture and characteristics of the Bayesian framework can be found in Zammit-Mangion et al (2014) and Zammit-Mangion et al. (2015).
Data quality:
Uncertainty maps are provided for each of the variables, which are estimated within the Bayesian inversion method taking into account the full error covariance matrices for each data set. Further details are described in the publications related to the project (see references).
