Delta-X: AirSWOT Level 1B Interferogram Products in Radar Coordinates, 2021
This dataset contains AirSWOT interferogram products collected during the 2021 Delta-X Campaign over the Atchafalaya and Terrebonne Basins of the Mississippi River Delta, Louisiana, USA from 2021-03-26 to 2021-04-18 (Spring) and 2021-08-21 to 2021-09-12 (Fall). AirSWOT uses near-nadir wide-swath Ka-band radar interferometry to measure water-surface elevation and produce continuous gridded elevation data. AirSWOT elevation data is useful for calibrating elevation and slopes along the main channels, as well as tying observations to open ocean tidal conditions. The AirSWOT Level 1B (L1B) data products represent interferogram data in the radar coordinate system, not in georeferenced map coordinates. This is an earlier stage of data processing which is used to generate the later Level 2 and Level 3 data products which will contain georeferenced water heights and water height profiles for river channels in each basin. The data are provided in binary and text file formats.
SWOT Level 1B Low-Rate Interferogram Data Product, Version C
Interferograms for each of the 9 Doppler beams formed and spatially averaged (low rate) by the On Board Processor, corrected on the ground for phase biases (inherent to the processing applied on board). The geometry of the measurements is also reported for use in subsequent processing. Gridded; full swath for each half orbit. Available in netCDF-4 file format.<br>Please note that this collection contains SWOT Version C science data products.
Pre-Delta-X: L1 UAVSAR Single Look Complex and Interferograms, MRD, LA, USA, 2016
This Level 1 (L1) dataset includes single look complex (SLC) stack products and co-registered interferograms in the HH (horizontal transmit and horizontal receive) polarization for the Atchafalaya Basin, in Southern Louisiana, USA, within the Mississippi River Delta (MRD) floodplain. The data were collected in October 2016 by Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR), a polarimetric L-band synthetic aperture radar flown on the NASA Gulfstream-III aircraft as part of the Pre-Delta-X campaign. A single study region, flight line "gulfco_12011", was sampled six times at approximately 30-minute intervals to monitor changing water levels. The SLC stack product is a standard UAVSAR product delivered by the UAVSAR processing team. The L1 interferograms were generated from the SLC stacks.
SWOT Level 1B Low-Rate Interferogram Data Product, Version D
Interferograms for each of the 9 Doppler beams formed and spatially averaged (low rate) by the On Board Processor, corrected on the ground for phase biases (inherent to the processing applied on board). The geometry of the measurements is also reported for use in subsequent processing. Gridded; full swath for each half orbit. Available in netCDF-4 file format.
Sentinel-1 interferograms and weather-based tropospheric delays maps (ERA5, GACOS) for two volcanoes: Piton de la Fournaise and Merapi
<div> <p>InSAR Sentinel-1 dataset and weather-based models used in the paper "Benefits of GNSS local observations compared to global weather-based models for InSAR tropospheric corrections over tropical volcanoes: case studies of Piton de la Fournaise and Merapi" by Albino et al. (2024).</p> <p>The two zip files are associated with the two targets: REUNION_ISLAND and MERAPI. The directories "ERA5" and "GACOS" contain the GACOS and ERA5 tropospheric delay maps per epoch in geotiff format, respectively. The directory "INTERFEROGRAM" contains the unwrapped interferograms in geotiff format. The "AUX" directory contains the DEM and incidence angle in geotiff format.</p> </div>
ARIA Sentinel-1 Geocoded Unwrapped Interferograms
Level-2 interferometric products generated by the Jet Propulsion Lab (JPL) ARIA project. The creation, discovery, and distribution of these products support InSAR science around tectonically active regions, volcanoes, or areas of subsidence/uplift. The generation of the ARIA-S1-GUNW products was in part funded through collaborations with the AWS Open Data Program and NASA ROSES.
SWOT Level 1B Low-Rate Interferogram Data Product, Version 2.0
Interferograms for each of the 9 Doppler beams formed and spatially averaged (low rate) by the On Board Processor, corrected on the ground for phase biases (inherent to the processing applied on board). The geometry of the measurements is also reported for use in subsequent processing. Gridded; full swath for each half orbit. Available in netCDF-4 file format.

SAR Interferograms for NISAR Quasi-quad pol mode study
This dataset contains a collection of HH and VV interferograms collected with the JPL Airborne system UAVSAR. The interferogram cover various regions: - Winnipeg, Canada -Kenaston, Canada -Stuttgard, Arkansas, USA The data has been used to study the impact of NISAR quasi-quad pol mode on the computation of the ionospheric phase screen. The data are provided in a GDAL format and can be opened and handled using Python. The research was carried out at the Jet Propulsion Laboratory, California Institute of Technology © 2020.
