Non-linear motions of Australian geodetic stations induced by non-tidal ocean loading and the passage of tropical cyclones

Memin, A; Watson, Christopher Stephen; Haigh, Ivan D.; MacPherson, L; Tregoning, Paul

Description

We investigate daily and sub-daily non-tidal oceanic and atmospheric loading (NTOAL) in the Australian region and put an upper bound on potential site motion examining the effects of tropical cyclone Yasi that crossed the Australian coast in January/February 2011. The dynamic nature of the ocean is important, particularly for northern Australia where the long-term scatter due to daily and sub-daily oceanic changes increases by 20–55 % compared to that estimated using the inverted barometer (IB)...[Show more]
