Science - Sea Level And Ice (329C): People: Johan Nilsson

GRACE
GRACE, the Gravity Recovery and Climate Experiment, provide measurements of the Earth’s gravity field, including the variability of ocean mass.

ISSM
ISSM (Ice and Sea-level System Model) is a state of the art ice flow modeling software developed at JPL in collaboration with University of California Irvine.
