A satellite-mounted instrument has in just one year produced higher-resolution imagery of the global seafloor than that from comparable systems over the past 30 years. 'Sea' for yourself and learn more about the new study led by Scripps Oceanography postdoctoral scholar Yao Yu. ⬇️

Happy #AGU24! If you're interested in learning about how InSAR closure phase can be used to measure moisture in soil, vegetation, or wildfire fuel materials, check out my poster Wednesday morning and talk Wednesday evening!

My first first-author paper is finally published! 🥳🛰️ "Fine-Resolution Measurement of Soil Moisture from Cumulative InSAR Closure Phase" This is the cumulative work of the 1st half of my PhD, and I'm so excited to be able to share the final product! 😄 bit.ly/closuresoil

Fine-Resolution Measurement of Soil Moisture From Cumulative InSAR Closure Phase

Soil moisture can vary spatially at the scale of agricultural fields (~10–100 m), which is generally too fine to resolve using passive radiometric methods. Active radar provides an opportunity for fin...

If you use SBAS or distributed scatterer time series for InSAR, you may be unknowingly aliasing your data! A new paper by my labmate Karissa Pepin explores how aliasing sneaks into InSAR time series & how to tailor temporal baselines to minimize this effect: bit.ly/aliasinsar

Aliasing in InSAR 2-D Phase Unwrapping and Time Series

We quantify and characterize an often-overlooked error source in interferometric synthetic aperture radar (InSAR) and derived time series: aliasing from insufficiently sampled interferograms in space ...

AGU23 has me wishing I could split myself in half!   Tomorrow (Tues) from 9:10-9:20 a.m., I encourage you to watch my advisor discuss our work on modelling InSAR closure phase to measure high-resolution soil moisture…
