Terrestrial Analogs to Titan for Geophysical Research

open access: yesReviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

Initial Atmospheric Waves Experiment (AWE) Imaging Analyses: Gravity Wave Sources, Temperatures, Pseudomomentum Fluxes, and Horizontal Wavenumber Spectra at the OH Layer

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract The NASA Atmospheric Waves Experiment (AWE) employs an OH imager that began measurements aboard the International Space Station (ISS) on 22 November 2023. The motivation for AWE was to quantify gravity wave (GW) responses to diverse sources and their influences extending into the mesosphere and higher altitudes.

Lightning Outbreaks at the Mature Stage of Tropical Cyclone: Case Study for Hurricane Dorian (2019)

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract The relationship between tropical cyclone (TC) lightning activity and intensity change has been examined for nearly 30 years, yet a clear consensus remains elusive, reflecting the complexity of the processes governing TC lightning. This study investigates the physical mechanisms that triggered inner‐core lightning outbreaks during the mature ...

Airborne polarimetric Doppler weather radar: Trade-offs between various engineering specifications [PDF]

open access: yes2016 IEEE International Symposium on Phased Array Systems and Technology (PAST), 2016
NCAR/EOL is investigating potential configurations for the next generation airborne phased array radar (APAR) that is capable of retrieving dynamic and microphysical characteristics of clouds and precipitation. A number of antenna aperture configurations, and signal processing algorithms will be used for realizing overall performance of the APAR.
