Abstract The Solar, Anomalous, and Magnetospheric Explorer (SAMPEX) mission launched in July 1992 was the first NASA “Small Explorer” project. It had the goal to show how space missions could be developed much more rapidly than had become the situation in the 1980s and 1990s.

Microburst precipitation phenomena.
Auroral zone microburst electron precipitation is reviewed. It can be shown from existing data that microbursts represent a major precipitation form on the dayside magnetosphere. Balloon X-ray data indicate that microbursts are periodic and they are small-scaled. Rocket and sattellite data indicate that microbursts may consist of substructures and that

A note on the control against microburst.
Flights against microburst are analysed as optimal control problems. A typical microburst model is used with a Dryden gust model superimposed on it. Control laws are those of an optimal regulator with Kalman-filter for noisy measurements. The result shows the importance of the accurate measurements of ground and air velocity as well as climb rates. The

Abstract Earth's radiation belts are the regions where highly energetic charged particles are trapped by Earth's magnetic field, posing significant risks to the satellites and other space‐based technologies. Understanding the dynamics of the radiation belts is critical not only for advancing fundamental plasma physics but also for predicting and ...

The Bayesian sinking in Porticello: a predictable convective windstorm?
The meteorological phenomenon that led to the Bayesian yacht sinking in Sicily at 0206 utc on 19 August 2024 is here investigated. A thunderstorm occurred during the sinking, but uncertainties exist regarding whether a waterspout or a downburst affected the ship. An in‐depth analysis of available observations highlighted that the ship was likely struck

Abstract The precipitation of tens to hundreds of keV electrons from Earth's magnetosphere plays a crucial role in magnetosphere‐ionosphere coupling, primarily driven by chorus wave scattering. Most existing simulations of electron precipitation rely on test particle models that neglect particle feedback on waves.

Mitigating Microbursts by Packet Recirculation in Programmable Switch
Microbursts pose a significant challenge in 5G networks, leading to packet drops and high latency that impact user experience. Existing mitigation systems often suffer from transmission delays, high packet drop rates, and potential failure due to ...

Real-time anomaly detection is a core requirement in high-speed networks, yet most intrusion detection systems struggle with short-lived microbursts and stealthy data exfiltration, especially when attackers hide within bursty traffic. This paper proposes

Analysis and modeling of microburst precipitation
Observations from a recent rocket experiment that measured electrons over the energy range of 1–300 keV shows that microburst temporal structures exist from about 20 keV to >120 keV. Simultaneous observations at five different pitch‐angles (0°–90°) show the distribution is nearly isotropic during the bursts, while at low activity (quiet times and ...

A microburst encounter near the ground was documented for the first time at Hong Kong International Airport (HKIA). Analysis of the flight data for the concerned aircraft revealed that it passed through at least three small vortices within the band of ...
