Rates of Vertical Land Motion (VLM) on Tutuila (American Samoa) and Upolu (Samoa) (from 3 December 2015 to 16 April 2020 and from 28 April 2020 to 27 November 2023)

<p>Dataset associated with the resubmitted manuscript under revision "Spatiotemporal Patterns of Subsidence and Sea Level Rise in the Samoan Islands Nearly 15 Years after the 2009 Samoa-Tonga Earthquake" by S. A. Huang, J. M. Sauber, S.-C. Han, R. Ray, and E. J. Fielding.</p> <p>Average VLM rates are provided for Tutuila (American Samoa) and Upolu (Samoa) over two subsets:</p> <ol> <li>3 December 2015 to 16 April 2020</li> <li>28 April 2020 to 27 November 2023</li> </ol> <p>VLM rates were derived using the PS-InSAR technique described in the publication at https://doi.org/10.1109/LGRS.2024.3358737.&nbsp;</p> <p>The following files are included here:</p> <ul> <li>plot_ps_data_tutuila_upolu.m: Matlab script to visualize the data included in all the *.mat files (Figures 4 and 5 and the histograms in 8c and 9c without annotations).
