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.

Evaporation and Cold Pools Beneath Trade Cumulus Clouds

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract The sources of air and water vapor in the tropical trade‐wind Atlantic subcloud boundary layer (SBL) are analyzed using in situ measurements of temperature, specific humidity, and stable water isotopologues (HDO and H218O) from shipboard observations in January‐February 2020.

Displaced geostationary orbits using hybrid low-thrust propulsion

, 2010
In this paper, displaced geostationary orbits using hybrid low-thrust propulsion, a complementary combination of Solar Electric Propulsion (SEP) and solar sailing, are investigated to increase the capacity of the geostationary ring that is starting to ...

GOLD Nighttime Limb Observations: A New Data Set for Investigating the Altitude‐Latitude Structure and Temporal Variability of the Equatorial Ionization Anomaly

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Using NASA's Global‐scale Observations of the Limb and Disk (GOLD)'s Dark Limb Mode (DLM) observations, we provide a multi‐year characterization of nighttime Equatorial Ionization Anomaly (EIA) morphology and variability. From geostationary orbit, GOLD measures OI 135.6 nm limb radiance at ∼33°E and ∼128°W longitudes, yielding routine, time ...

Autonomous control of a reconfigurable constellation of satellites on geostationary orbit with artificial potential fields

, 2012
This paper presents a method of controlling a constellation of small satellites in Geostationary Earth Orbit (GEO) such that the constellation is able to reconfigure - changing the angular position of its members relative to the Earth’s surface in order ...

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.

Thermal infrared shadow-hiding in GOES-R ABI imagery: snow and forest temperature observations from the SnowEx 2020 Grand Mesa field campaign [PDF]

The Cryosphere
The high temporal resolution of thermal infrared imagery from the Geostationary Operational Environmental Satellites R-series (GOES-R) presents an opportunity to observe mountain snow and forest temperatures over the full diurnal cycle.
