AI Based Velocity Calibration for Cassini's Cosmic Dust Analyzer (CDA)

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract This paper presents a novel AI‐based velocity calibration method for the Cosmic Dust Analyzer (CDA) onboard the Cassini spacecraft, in particular for impacts on the large Impact Ionization Detector (IID). The legacy polynomial calibration function, derived from laboratory measurements at a dust accelerator facility, assigns a velocity ...

Localization and Classification of Gravity Wave Events From VIIRS Day/Night Band Satellite Imagery Using Machine Learning Techniques

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Gravity waves in the upper mesosphere produce diverse spatial patterns in nighttime airglow, but their global morphology has been difficult to characterize because manual identification is impractical for the massive satellite image archive. We developed a machine learning framework to detect and classify gravity wave events in imagery from ...

Implementation of the Deep Blue Aerosol Algorithm on Geostationary Satellite Data

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract National Aeronautics and Space Administration's Deep Blue (DB) aerosol project aims to produce consistent, long‐term climate data records of atmospheric aerosol properties using satellite observations. The DB algorithm has been extensively applied to low Earth orbit (LEO) sensors, including the Moderate Resolution Imaging Spectroradiometer and

Geometry‐Dependent Surface Lambertian‐Equivalent Reflectivity (GLER) Climatology for the TEMPO Mission

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract We describe a Geometry‐dependent surface Lambertian‐Equivalent Reflectivity (GLER) climatology developed to support operational retrievals for the Tropospheric Emissions: Monitoring of Pollution (TEMPO) mission. This data set provides monthly and hourly surface reflectance for snow‐free land, snow‐covered land, and oceanic regions.

Hydrothermal Manganese‐Oxide Mineralization of a Carbonate Ooze, Samoan Hotspot Region, South Pacific Ocean

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract Low‐temperature hydrothermal manganese oxides occur throughout the global oceans. However, the hydrothermal replacement of a carbonate ooze by manganese oxides is described here for the first time. The 24 samples dredged from three locations around the Territory of American Samoa in the South Pacific Ocean include six samples with remnant ...
