Advanced InSAR atmospheric correction: MERIS/MODIS combination and stacked water vapour models [PDF]

, 2009
A major source of error for repeat-pass Interferometric Synthetic Aperture Radar (InSAR) is the phase delay in radio signal propagation through the atmosphere (especially the part due to tropospheric water vapour).

An aseismic slip pulse in northern Chile and along-strike variations in seismogenic behavior [PDF]

, 2006
We use interferometric synthetic aperture radar, GPS, and seismic observations spanning 5 to 18 years to reveal a detailed kinematic picture of the spatiotemporal evolution of fault slip in a region corresponding to the 30 July 1995 M_w 8.1 subduction ...

GPS source solution of the 2004 Parkfield earthquake [PDF]

, 2014
We compute a series of finite-source parameter inversions of the fault rupture of the 2004 Parkfield earthquake based on 1 Hz GPS records only. We confirm that some of the co-seismic slip at shallow depth (
