A Cloud Screening Preprocessing Framework for GOCI‐II Aerosol Optical Depth: Development and Impact on Retrieval Errors

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 1, 16 January 2026.
Abstract Accurate retrieval of satellite‐derived aerosol optical depth (AOD) is critical for air quality forecasting, especially when AOD is assimilated into models. However, if retrieval errors in the satellite‐derived AOD are not corrected or characterized, they can lead to false analysis increments and ultimately degrade the quality of data ...

Topside Ionization and Effect on Altitudinal Evolution of Nocturnal Ionospheric Irregularities

open access: yesSpace Weather, Volume 24, Issue 1, January 2026.
Abstract Topside ionospheric electron density (Ne) and its control on the variabilities in nocturnal ionospheric irregularities is examined globally using electron density measurements from COSMIC‐2 and Swarm satellite, along with the Swarm satellite‐based Ionospheric Plasma Irregularity (IPIR) index for low and high solar activity (LSA and HSA ...

Trees Outside Forests (TOFs): A Global Review of Methodological Advances, Limitations, and Framework Innovations

open access: yesInternational Journal of Forestry Research, Volume 2026, Issue 1, 2026.
Trees outside forests (TOFs) represent an important natural and anthropogenic resource that contributes significantly to biodiversity conservation, climate resilience, and the protection of forest genetic resources (FGRs). Despite their ecological and socioeconomic importance, TOFs are increasingly declining due to land‐use changes, urbanization ...

Machine Learning‐Based Turbulence Intensity Estimation Near Convective Clouds in East Asia Using GK‐2A Satellite Observations

open access: yesGeophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract The detection of atmospheric turbulence, particularly near deep convection, are essential for flight safety and efficiency. Geostationary satellites provide continuous coverage where radar is unavailable, but their lack of vertical information limits detection to upper levels.

Comprehensive Analysis of Bias in TEMPO NO2 Column Densities Through Pandora Observations

open access: yesJournal of Geophysical Research: Atmospheres, Volume 130, Issue 15, 16 August 2025.
Abstract Tropospheric Emissions: Monitoring of Pollution (TEMPO) is the first geostationary satellite instrument to monitor air pollutants across North America. This study uses Pandora observations to analyze the bias in TEMPO Level‐3 total column density of NO2 (TOTNO2) from August 2023 to December 2024.

Systematic Slowing of Initially Rapid Retreat of New Coasts Formed by Historical Eruptions in Volcanic Islands

open access: yesJournal of Geophysical Research: Earth Surface, Volume 130, Issue 8, August 2025.
Abstract Due to their exposure to waves, volcanic island coasts typically retreat with cliff collapses and other erosional processes. Understanding how retreat rates vary over time and in response to environmental and other factors could be useful for geohazard assessment, coastal management and landform reconstruction.
