ItemNo Preview AvailableA Differential Approach for Rain Field Tomographic Reconstruction Using Microwave Signals from Leo SatellitesShen, X ; Huang, DD ; Vincent, C ; Wang, W ; Togneri, R (IEEE, 2020-01-01)A differential approach is proposed for tomographic rain field reconstruction using the estimated signal-to-noise ratio of microwave signals from low earth orbit satellites at the ground receivers, with the unknown baseline values eliminated before using least squares to reconstruct the attenuation field. Simulations are done when the baseline is modelled by an autoregressive process and when the baseline is assumed fixed. Comparisons between the reconstruction results for the differential and non-differential approaches suggest that the differential approach performs better in both scenarios. For high correlation coefficient and low model noise in the autoregressive process, the differential approach surpasses the non-differential approach significantly.

ItemSlip rate estimation from tilting of marine terraces above an offshore listric thrust fault, Kaikoura, New ZealandDuffy, B ; Clark, KJ ; Upton, P ; Langridge, R ; Kelly, K ; Hammond, K (GNS Science, 2017-11-13)Slip on an offshore fault uplifted and tilted the Kaikoura Peninsula during the 2016 Kaikoura earthquake. Analysis of a 2012, 1m Lidar DEM shows that the uplifted Kaikoura marine terraces have been progressively tilted in the same manner since 120 ka. A Monte-Carlo analysis of tilt-age relationships, based on a model of listric faulting, and using published age data and Papuan and regional sea level curves, implies that slip rates have increased from 2.3 ± 1.3 mm/yr to 4.1 ± 1.2 mm/yr since c.60 ka. Comparison of the elevation of young, uplifted beaches surrounding the peninsula, with a Late Holocene sea level curve, suggests three earthquake events (including 2016) over 3 kyr. The timing of the earthquakes implies lower Late Holocene slip rates, compared with post-60 ka slip rates; comparison of these events with paleoseismic records of the Marlborough Fault System is interpreted to suggest latest Holocene clustering of seismicity.
