Science / project summary
This project will continue operation of the Greenland GPS Network (GNET). GNET has proven highly successful in "weighing" the Greenland ice sheet by tracking the earth's elastic response to changing surface loads. The PIs will extend the life of GNET so that it can continue to sense space-time changes in ice mass, including spatial shifts in the position of the centers of ice loss, and accelerations in mass change rates. GNET is now resolving seasonal oscillations in the vertical and horizontal position of the earth's crust as well as longer-term trends. These oscillations reflect seasonal changes in the loads placed on the solid earth by both the atmosphere and the ice sheet. The atmospheric pressure signal can be removed, using state-of-the-art weather models, in order to isolate the signal due to changes in the ice sheet. As part of the pressure analysis, they will also produce a time series of integrated water vapor for each station in GNET, with benefits for weather and climate predictions. Scientifically, GNET is addressing a problem of great interest and also considerable societal importance: the trajectory and magnitude of Greenland mass balance. With current and potential additional gaps in satellite geodesy coverage of Greenland, GNET is a cornerstone of our observations of the cryosphere. The data are openly accessible and are available in near real-time through UNAVCO. Level 2 data - 3D time series of solid earth deformation for the cryosphere community is available from DTU Space: ftp://ftp.spacecenter.dk/pub/abbas/GNET/v1/).
