Deriving a global and hourly data set of aerosol optical depth over land using data from four geostationary satellites: goes-16, msg-1, msg-4, and himawari-8

open access: yes, 2019
Due to the limitations in the number of satellites and the swath width of satellites (determined by the field of view and height of satellites), it is impossible to monitor global aerosol distribution using polar orbiting satellites at a high frequency ...

Impacts of Mid‐Latitude Ionospheric Dynamics on RF Applications During the November 2025 Superstorm Event

open access: yesGeophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract This study demonstrates the intriguing and complex interplay among auroral precipitation, enhanced TEC, density irregularities, and amplitude scintillations observed during the November 2025 superstorm. For the first time, we present observations of strong amplitude scintillation across continental United States (CONUS)—nearly from coast to ...

Horizontal and Vertical Structure of Cloud Effective Radius in Eastward‐Propagating Convective Systems

open access: yesGeophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Organized convective systems produce a disproportionate fraction of warm‐season rainfall, yet satellite‐based analyses generally neglect propagation‐relative microphysical organization. We develop a propagation‐relative partitioning framework using FY‐4A geostationary satellite observations to characterize sector‐resolved cloud effective ...

Proposal for an ionosphere/plasmasphere monitoring system

open access: yesAnnales Geophysicae
A space-based satellite system suited for long-term monitoring of the Earth's ionosphere/plasmasphere systems is proposed. The monitoring system consists of a network of radio beacon satellites capable of measuring the ionospheric and plasmaspheric ...

Validation of Sea Surface Temperature From GK-2A Geostationary Satellite and Error Reduction Considering Impact of Satellite Zenith Angle

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
This study evaluates the accuracy of sea surface temperature (SST) data produced by Korea's second geostationary satellite, GK-2A, over its first four years of operation (2019–2023).

Resolving Convective‐Scale Cloud and Precipitation Structures in Tropical Cyclone Rainbands With Novel Raman Lidar Observations

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract Low‐level clouds in the tropical cyclone (TC) rainbands modulate the radial inflow of warm, moist boundary layer air, which can impact TC intensity. Yet, precisely measuring rainband cloud boundaries with existing remote sensing techniques remains a challenge.

Morphology‐Driven Ternary Pattern Space Spans Shallow Marine Clouds

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract Marine shallow clouds exhibit a variety of patterns, which have been the subject of extensive research. In this study, we introduce a new approach for their continuous classification using Moderate Resolution Imaging Spectroradiometer (MODIS) true color imagery.

Helium Ion‐Induced Degradation Mechanisms in Optical Coatings for Space Applications

open access: yesAdvanced Optical Materials, Volume 14, Issue 36, 25 September 2026.
Although low‐energy helium ions represent a significant source of degradation for optical coatings operating in space environments, their effects remain poorly understood. Systematic irradiation of over 150 metal and dielectric thin‐film samples at 4, 16, and 100 keV investigates the damage mechanisms and their impact on optical performance ...

Allocation of Orbit and Spectrum Resources for Regional Communications: What's at Stake? [PDF]

open access: yes
Contentious debate surrounds allocation of the geostationary orbit and electromagnetic spectrum, two resources used by communications satellites. An extensive economics literature alleges that the nonmarket administrative allocative procedures now in ...
