In this paper the potential of L-Band repeat-pass differential SAR interferometry for land subsidence monitoring is evaluated using JERS SAR data. Bologna, Mexico City and the Ruhrgebiet were selected as application sites representing slow to fast deformation velocities. The investigation includes feasibility aspects as the data availability, the temporal decorrelation over different landcover classes and the range of useful spatial baselines, an analysis of the achieved deformation accuracy and considerations on the complementarity to ERS SAR interferometry and levelling surveys. In spite of the rather limited data availability, land subsidence maps could be generated for the three selected application sites. Unlike with ERS C-Band SAR data, JERS L-Band interferometry permitted to retrieve subsidence values also over vegetated areas and forest when using interferograms of less than one year acquisition time interval and short baseline. In addition, the longer L-Band wavelength was found to be superior in the case of large deformation gradients that lead to phase unwrapping problems in C-Band interferometry.
