AbstractTime series of ground deformation are used to describe motion produced by various natural and anthropocentric processes, such as earthquakes, volcanic eruptions, landslides, subsidence due to resource exploitation and uplift due to fluid injection. The Multidimensional Small Baseline Subset version 3 (MSBASv3) software simultaneously processes multiple ascending and descending Differential Interferometric Synthetic Aperture Radar (DInSAR) data sets and produces either one-dimensional, line-of-sight, or two-dimensional, horizontal east-west and vertical, deformation time series with combined temporal resolution. The set of linear equations solved by MSBASv3 is usually rank deficient and is solved in the least-square sense by applying the Singular Value Decomposition (SVD) and the zero, first, or second order Tikhonov regularization. The MSBASv3 source code is written in C++ and is parallelized using OpenMP. It is linked to the Linear Algebra PACKage (LAPACK) library that provides SVD support and to the Geospatial Data Abstraction Library (GDAL) that provides GeoTiff support. To demonstrate the capabilities of the MSBASv3 a test set of ascending and descending RADASAT-2 data over the Barnes Ice Cap (Baffin Island, Nunavut, Canada) during December 2014 - May 2015 is included and is used throughout this user manual to illustrate the processing sequence.
