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 ...

The evolution of lunar communication—From the beginning to the present

International Journal of Satellite Communications and Networking, Volume 42, Issue 3, Page 200-216, May/June 2024.
Since the beginning of the space age, the Moon has been the target of many missions from the 1950s to the present day. Radio communication plays a fundamental role in space vehicle projects because this is the most obvious way to communicate with the ground station and transmit control commands and scientific data.

A Design Method for Redundant Microthruster Layout With Allocation Error

International Journal of Aerospace Engineering, Volume 2024, Issue 1, 2024.
The microthruster is generally chosen as the actuator of the drag‐free satellite control system, and the layout directly affects the stability of the satellite control. Due to the extremely rigorous objectives of drag‐free control, a design method for the redundant thruster layout is proposed in this paper to improve the control stability of the ...
