We used data from the German Space Agency\u2019s TerraSAR-X and TanDEM-X satellites (X-band, 3.1 cm radar wavelength) as well as the European Space Agency\u2019s Sentinel-1 satellite (C-band, 5.6 cm radar wavelength); both datasets covered a ~3-year time period from 2018 to 2021. Using persistent scatterer interferometry (PSI), we were able to observe several deforming features in the region with sub-centimeter\/year deformation rates. We also examined a version of the X-band data that we spatially averaged to the same pixel size as the Sentinel-1 imagery in order to separate out the effects of wavelength and pixel size on PSI accuracy and coverage. Overall, the largest number of stable PS points was found in the full-resolution X-band data, which was followed by the C-band data and then by the downsampled X-band data. Our analysis also included a subset of snow-free imagery so that we could assess the effect that snow-covered images had on the distribution and accuracy of PS points and the resulting time series. This analysis revealed that PS populations increased by 50\u201360% for the snow-free data when compared with analyses using the full datasets. The average deformation rates inferred from the time series generated using only snow-free images were nearly identical to those estimated from the full time series. We assessed the accuracy of the inferred rates through comparisons between the results of different datasets and with limited ground survey data. We found that all of the inferred deformation rates from each of the datasets agreed with in situ measurements in an area of known ground subsidence above an underground salt mine in Lansing, NY. The S1 datasets, however, had higher levels of noise.<\/jats:p>","DOI":"10.3390\/rs15071815","type":"journal-article","created":{"date-parts":[[2023,3,29]],"date-time":"2023-03-29T03:32:25Z","timestamp":1680060745000},"page":"1815","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Ground Displacements in NY Using Persistent Scatterer Interferometric Synthetic Aperture Radar and Comparison of X- and C-Band Data"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2027-1388","authenticated-orcid":false,"given":"Yusuf","family":"Eshqi Molan","sequence":"first","affiliation":[{"name":"Department of Earth and Atmospheric Sciences, Cornell University, Ithaca, NY 14850, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7240-3165","authenticated-orcid":false,"given":"Rowena","family":"Lohman","sequence":"additional","affiliation":[{"name":"Department of Earth and Atmospheric Sciences, Cornell University, Ithaca, NY 14850, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3616-3373","authenticated-orcid":false,"given":"Matthew","family":"Pritchard","sequence":"additional","affiliation":[{"name":"Department of Earth and Atmospheric Sciences, Cornell University, Ithaca, NY 14850, USA"}]}],"member":"1968","published-online":{"date-parts":[[2023,3,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"23109","DOI":"10.1029\/96JE01459","article-title":"Surface Deformation and Coherence Measurements of Kilauea Volcano, Hawaii, from SIR-C Radar Interferometry","volume":"101","author":"Rosen","year":"1996","journal-title":"J.
