Project Abstract |
The CGM InSAR focus group is a multi-institutional collaboration aiming to establish a consensus deformation model from Sentinel-1. The goals of the project are twofold: to build a consensus velocity and time series solution, and to research the impacts of various methodological choices on the results. Groups from five institutions in this working group (JPL, SIO, UCB, USGS, UCR) have organized themselves to produce consistent products that will ultimately be used together in the consensus CGM, and have begun to address several basic research questions related to InSAR processing. The results of this project will be valuable to the wider community as a deformation product. The InSAR working group will also establish a better understanding of best practices and error corrections, which can easily be adapted for use with data from the NISAR mission that has a similar temporal cadence to Sentinel-1. |
Intellectual Merit | This project works towards developing community-vetted deformation products that can help improve our understanding of errors in geodetic data processing. This will also further the goal of creating a 3-D integrated velocity field from GNSS and InSAR in southern California. |
Broader Impacts | This project is directly leading to the generation of a single geodetic product that will improve reproducibility, transparency, and accessibility of InSAR data. Non-experts in InSAR will be able to use this open-access product for research and educational purposes. |
