VLM rates across Tutuila Island from December 5, 2015 to August 16, 2022, derived using a redundant multi-primary variant of the PS-InSAR technique. Dataset associated with the submitted version of the publication "Mapping Vertical Land Motion in Challenging Terrain: Six-Year Trends on Tutuila Island, American Samoa, With PS-InSAR, GPS, Tide Gauge, and Satellite Altimetry Data" by S. A. Huang, J. M. Sauber, and R. Ray. Available at https://doi.org/10.1029/2022GL101363.
ampl.mat: Amplitude backscatter averaged from all scenes, multilooked for speckle reduction and resampled to the dataset size.
latvals.mat: Latitude vector associated with the dataset.
lonvals.mat: Longitude vector associated with the dataset.
vlm_avg.mat: Average VLM across Tutuila Island. All non-PS have an "NaN" value.
vlm_stdev.mat: Standard deviation of VLM across Tutuila Island. All non-PS have an "NaN" value.
