Ohio State is in the process of revising websites and program materials to accurately reflect compliance with the law. While this work occurs, language referencing protected class status or other activities prohibited by Ohio Senate Bill 1 may still appear in some places. However, all programs and activities are being administered in compliance with federal and state law.

AirSWOT Data on the Willamette River

AirSWOT Data on the Willamette River

 

We used a dataset of Ka-band interferometric synthetic aperture radar (inSAR) measurements of water surface elevations over the Willamette River in Oregon, USA to test discharge algorithms which are under development for the Surface Water and Ocean Topography (SWOT) mission. This data was collected in March 2015 using AirSWOT (https://swot.jpl.nasa.gov/airswot.htm), an airborne instrument developed to support pre-SWOT activities and SWOT calibration/validation. 

In-situ data can be accessed at the USGS ScienceBase catalog for the level logger data, Bathymetry and stream velocity data, and boat-based water surface elevation surveys:
