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 ...

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 ...

VIIRS Global Area Coverage (VGAC): A reduced resolution VIIRS dataset for climate data record continuity

. The Visible Infrared Imaging Radiometer Suite (VIIRS) instrument represents a significant change from the legacy weather satellite observations. For example, there are several differences in scanning strategy, channels, file structure, etc.

Rising Aerosol Burdens in the Warm Desert City of Phoenix, AZ: Hydroclimatic–LULC Drivers and Exposure Disparities in a Climate–Land Surface–Society Framework

Earth's Future, Volume 14, Issue 9, September 2026.
Abstract Desert cities in the U.S. Southwest experience the nation's highest aerosol burdens, but how air pollution co‐evolves with hydroclimatic–LULC metrics and racial/ethnic exposure dynamics remains unclear. We developed 30 m Landsat‐derived summer aerosol optical depth (AOD) (2000–2020) for Phoenix, used explainable machine learning to attribute ...

Evaluating the Ability of NPP-VIIRS Nighttime Light Data to Estimate the Gross Domestic Product and the Electric Power Consumption of China at Multiple Scales: A Comparison with DMSP-OLS Data

Remote Sensing, 2014
The nighttime light data records artificial light on the Earth’s surface and can be used to estimate the spatial distribution of the gross domestic product (GDP) and the electric power consumption (EPC).

U‐Net Based Machine Learning for Identification of Auroras in Space‐Based Images

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract We use a Semantic Segmentation based U‐Net model to predict the appearance of various classifications of aurora present in near‐infrared images from the Fast Auroral Imager (FAI) onboard the CASSIOPE satellite. We manually labeled pixels from a set of 4091 FAI near‐infrared images into 7 different classes: no aurora, contaminated, diffuse ...

Evaluation of VIIRS and MODIS Thermal Emissive Band Calibration Stability Using Ground Target

Remote Sensing, 2016
The S-NPP Visible Infrared Imaging Radiometer Suite (VIIRS) instrument, a polar orbiting Earth remote sensing instrument built using a strong MODIS background, employs a similarly designed on-board calibrating source—a V-grooved blackbody for the Thermal

Surface‐State Controls on Dust Emission Variability in Lower Mesopotamia and Kuwait Using Field and Multi‐High‐Resolution Satellite Data

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 9, September 2026.
Abstract Aeolian dust strongly influences climate, air quality, and biogeochemical cycles, yet identifying source areas and determining their surface‐state controls remain challenging. We focus on lower Mesopotamia and Kuwait, a globally significant dust source region where surface characteristics of dust sources remain poorly understood through ...
