Antarctica crustal thickness model

Antarctica crustal thickness model (Llubes et al. 2018)

We present a global map of Antarctic crustal thickness computed from space gravity observations as presented in Llubes et al. (2018).  The crustal thickness model is provided in a grid Llubes 2018 Antarctica Crustal thickness.

Crustal thickness of Antarctica (Llubes et al., 2018). Units km.
Antarctica ice sheet and bedrock gravity effects (Llubes et al., 2018). Units mGal.
 Bouguer anomalies over Antarctica from GOCE Free Air Anomalies (Llubes et al. 2018). Units mGal.

Please, read the following document concerning grids format readme.

Other grids provided are:

Terrain gravity effects of ice, sea and surface rock derived from BEDMAP products (Fretwell et al. 2013).

Grids are available at resolutions of 5km Llubes 2018 Antarctica Terrain gravity effect and GOCE resolution 77km Llubes 18 Antarctica Terrain gravity effects 77 km

Bouguer anomalies estimated using free air anomalies of DIR5 gravity model (Bruinsma et al. 2014) Llubes 18 Antarctica Bouguer Anomalies.
