GPS source solution of the 2004 Parkfield earthquake [PDF]

open access: yes, 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 (

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

open access: yes, 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).
