Methods for substituting onsite ambient ultraviolet radiation measurements for personal exposure studies

Photochemistry and Photobiology, EarlyView.
Three methods for substituting on‐site ambient ultraviolet radiation measurements for personal exposure measurements were investigated. Assuming spatial persistency of measurements from high‐grade instruments delivers lowest uncertainties up to distances of 82 km.

A Machine Learning Framework for Retrieving Atmospheric Composition and the Associated Averaging Kernels From a Geostationary Hyperspectral Infrared Sounder

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Geostationary hyperspectral infrared sounders provide hourly observations of the atmospheric composition. However, the conventional optimal estimation method (OEM)‐based retrieval algorithm requires computationally expensive radiative transfer calculations and inverse modeling, making it difficult to monitor in real time. This study presents a

Simulating Regional‐Scale Aerosol Radiative Effects of Wildfire Smoke Using a High‐Resolution Coupled Meteorology‐Chemistry Model: HRRR‐Chem

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 18, 28 September 2026.
Abstract Wildfires are increasing in frequency and intensity, strongly influencing both regional air quality and the Earth's radiation budget via their aerosol emissions. Relying on an unparalleled observational data set from the 2019 NOAA/NASA FIREX‐AQ campaign, this study quantifies the direct radiative effects of two wildfires using the HRRR‐Chem ...

Statistics of glinting clouds observed by DSCOVR and geostationary satellites

Frontiers in Remote Sensing
This study examines how frequently the specular reflection of sunlight—that is, sun glint—reveals the presence of ice crystals that maintain a steady horizontal orientation.

Quantifying Cloud‐Fog‐Induced Reductions in Near‐Surface Solar Radiation Using the Reduction Ratio Method

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Cloud‐fog formation substantially reduces near‐surface solar radiation and modulates land‐atmosphere interactions, but quantifying such reduction is limited by sparse mountain observations. Using a 1‐km geostationary satellite‐retrieved product, we apply the Reduction Ratio of Solar Radiation (RRSR), an empirical normalized metric that ...

Inter-Satellite Link Optimization of Two Collocated Geostationary Satellites

IEEE Access
With the growing number of geostationary satellites and the limited availability of orbital slots, satellite operators increasingly collocate multiple satellites within the same slot, necessitating coordination through inter-satellite links (ISL).
