Seminar: WVNet: A SAR Foundational Model with Applications for Air-sea Interaction Research
Marine Science Building 100 1000 Pope Road, HonoluluYannik Glaser PhD Candidate in Information and Computer Science Department of Atmospheric Sciences University of Hawai’i at Mānoa Justin Stopa Associate Professor Department of Ocean and Resources Engineering University of Hawai’i at Mānoa Location Information **This seminar will be held both in person (Marine Sciences Building 100) and over Zoom** Zoom Invitation Link: https://hawaii.zoom.us/j/98919200762 Meeting ID: 989 1920 0762 Passcode: 201326 Synthetic aperture radars (SAR) aboard space-borne satellites measure sub-mesoscale oceanic and atmospheric phenomena at a global scale. This work uses the European Space Agency (ESA) Sentinel-1 (S-1) SAR mission’s sea surface roughness to study sub-mesoscale phenomena such as turbulence
MS Plan B Defense: Estimating marine atmospheric boundary layer stratification with synthetic aperture radar data
Jonathan B. Chapman, PE Department of Ocean & Resources Engineering University of Hawai‘i at Mānoa Location Information **This defense will be held both in person (Kuykendall Hall 101) and over Zoom** Meeting ID: 914 1679 5922 Passcode: 808795 https://hawaii.zoom.us/j/91416795922 Uncertainties in the lower atmosphere’s stratification, which is the balance between buoyancy and shear, lead to large uncertainties when determining air-sea fluxes. Previous works show that synthetic aperture radar (SAR) sea surface roughness images show atmospheric phenomena that are known to be related to stratification. In this project, we hypothesize that physics-guided neural networks (PGNNs) can be used to estimate
Seminar: Relating Observed Marine Boundary Layer Cells, Rolls, or Their Absence to Surface Layer Stratification Using Sentinel-1 SAR Data

This lower portion of the atmosphere interacts with the ocean and exchanges gas and heat which drives the weather and climate. Datasets describing the lower portion of the atmosphere in the open ocean are sparse. We are motivated to fill this data gap by proposing a marine atmospheric boundary layer state indicator
