The Effect of Water Vapor and Solar Zenith Angle on Oceanic Diurnal Warming

Geophysical Research Letters, Volume 52, Issue 9, 16 May 2025.
Abstract Oceanic diurnal warm layers have been extensively studied over the years due to their important role in a variety of geophysical disciplines. Much of this research has been dedicated to the development of predictive models of varying complexity to calculate the spatiotemporal magnitude of the effect. This manuscript presents results which show

Magnetospheric Cold Plasma Diagnostics Using High Altitude GNSS Signals

Journal of Geophysical Research: Space Physics, Volume 130, Issue 3, March 2025.
Abstract The plasmasphere is a key component of Earth's magnetosphere, regulating numerous energy transfer processes. The plasmasphere is also a cold multi‐species plasma. Tracing differences in dynamics between low and high mass cold ions is important for identifying the processes that drive plasmaspheric evolution.

Seasonal and Local Time Variation in the Observed Peak of the Meteor Altitude Distributions by Meteor Radars

Journal of Geophysical Research: Atmospheres, Volume 129, Issue 21, 16 November 2024.
Abstract Meteoroids of sub‐milligram sizes burn up high in the Earth's atmosphere and cause streaks of plasma trails detectable by meteor radars. The altitude at which these trails, or meteors, form depends on a number of factors including atmospheric density and the astronomical source populations from which these meteoroids originate.

Influence of Ocean Currents on Wave Modeling and Satellite Observations: Insights From the One Ocean Expedition

Journal of Geophysical Research: Oceans, Volume 129, Issue 11, November 2024.
Abstract This study investigates the influence of ocean currents on wave modeling and satellite observations using in situ wave measurements from the One Ocean Expedition 2021–2023. In January 2023, six OpenMetBuoy drifters were deployed in the Agulhas Current region.

Evaluation of Modeled Diurnal Warming Estimates for Application to Producing Sea Surface Temperature Analyses

Earth and Space Science, Volume 11, Issue 9, September 2024.
Abstract Accurate knowledge of the amount of diurnal warming present in sea surface temperature (SST) observations at different times and effective depths is important for multiple applications including the production of blended SST analyses. This work explores the ability of a modified Kantha‐Clayson‐type one‐dimensional mixed layer ocean model with ...
