GIAinv

this project contains Matlab scripts and dataset to separate Glacial Isostatic Adjustment (GIA) signal and Present Day Surace Mass Change (PDSMC) signal in contemporary GNSS observations and GRACE data.

the main matlab function is GIA_inv_GPS_GRACE.m and it has comments that explain the function

to help with a trial run we also provide some sample data (such as Caron_stokes.mat, ICE_6GD_stokes.mat, GRACE_trebd_Data.mat, GPSloc_vec.mat, and GPS_trend_vec.mat)

User may follow the example in GIA_inv_GPS_GRACE.m to obtain a GIA field or PDSMC field from the dataset.

the file: GIA_output_GNSS_GRACE_ice6G_purcell.mat contains the GIA field that we obtained for the publication.

the file GIA_VLM_1deg.nc contains the high resolution GIA field that is obtained by applying the forward modelling approach (by Chen et al., 2015) on the GIA field GIA_output_GNSS_GRACE_ice6G_purcell.mat
