Interferometric Synthetic Aperture Radar (InSAR) for Monitoring Seasonal Snow

Water Resources Research, Volume 62, Issue 9, September 2026.
Abstract Interferometric Synthetic Aperture Radar (InSAR) offers a potential pathway for measuring seasonal snow water equivalent (SWE) and snow depth at spatial and temporal scales needed for basin‐scale hydrology. First proposed for seasonal snow more than 25 years ago, InSAR uses repeat‐pass radar phase differences to estimate changes in SWE or ...

Satellite‐Based Fishing Fleet Tracking: A New Foundation for Fisheries Science and Management

Fish and Fisheries, Volume 27, Issue 5, Page 1134-1150, September 2026.
ABSTRACT Satellite‐based vessel‐tracking technologies have ushered in a new era for monitoring fishing activity at scale. By combining artificial intelligence (AI) methods with remotely‐sensed data, researchers can now detect, classify and analyse fishing behaviour across vast and previously unobservable ocean regions.

A GEO‐LEO Imager Data Set for Characterizing Rapid Changes of Global Aerosol Properties

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.
Abstract Aerosols, the ubiquitous small particulates in our atmosphere, have climate, air quality, and/or other impacts far from their original sources. The Dark Target Algorithm (DTA), originally developed for retrieving aerosol properties from satellite imagers in Low‐Earth Orbit (LEO), has been ported to imagers in Geostationary (GEO) orbit. Using a

Vertical Coherence Dominates Decadal Land Water Storage Change Despite Hydroclimatic Extremes and Groundwater Pumping

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Whether surface and deeper water storage trends move in the same direction underpins assessments of freshwater availability. Theory predicts vertical coherence, yet it is untested globally and questioned under climate extremes and human management. Using depth‐sensitive satellite observations spanning surface soil moisture (SSM) (Soil Moisture

Daily Global Methane Super‐Emitter Detection and Source Identification With Sub‐Daily Tracking

Geophysical Research Letters
We use the Visible Infrared Imaging Radiometer Suite (VIIRS) satellite instruments to retrieve atmospheric methane enhancements with 750 m resolution. We show that the three VIIRS instruments in orbit uniquely enhance tracking of methane super‐emission ...

Rating the Effectiveness of Fishery Closures With Visible Infrared Imaging Radiometer Suite Boat Detection Data

, 2018
Fishery closures are widely used to promote the sustainability of fish stocks. Fishery agencies typically have very little data relevant to planning closure enforcement actions and evaluating the effectiveness of closures, due in part to the vast expanse

Methane Emissions From Wildfires: Trends and Anomalies

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.
Abstract Wildfires emit smoke particles and trace gases including greenhouse gases into the atmosphere, impacting the environment and leading to detrimental impacts on human health and economy. The estimation of spatially and temporally resolved methane emissions from biomass burning (BB) provides critical information in developing measurement‐informed
