A regional augmented PPP algorithm for offshore considering NWP by Ying Xu, Xiangdan Meng, Jianhui Cui, Lin Ma

“…Marine experiments indicate that the convergence time of this algorithm is 11–32% shorter than that of ionospheric-free PPP. The convergence time of this algorithm is reduced by 56–59%, and positioning accuracy in the E, N and U directions is augmented by 33.3%, 19.5% and 53.7%, respectively, compare to traditional augmented PPP at sea where the distribution of reference stations is inhomogeneous. …”

Low Altitude Tailing Es (LATTE): Analysis of Sporadic‐E Layer Height at Different Latitudes of Middle and Low Region by Qiong Tang, Chen Zhou, Huixin Liu, Yi Liu, Jiaqi Zhao, Zhibin Yu, Lianhuan Hu, Zhengyu Zhao, Xueshang Feng

“…Comparing winds from a combination of the Ionospheric Connection Explorer/Michelson Interferometer for Global High‐Resolution Thermospheric Imaging and meteor radar measurements with Es layers, we find that Es traces at high altitudes (above 110 km) rapidly move down in accordance with the descent of the wind shear nulls, which indicates the important role of the tides in the formation and descent of the Es layer at high altitude. …”

How geomagnetic storms affect the loss of Starlink satellites in February 2022? by Nizam Ahmad, La Ode Muhammad Musafar Kilowasid, Hanif Fakhrurroja, Neflia, Abdul Rachman, Asnawi Husin, Haries Fathoni

“…The reason for this is that, despite having lower altitudes, all decaying Starlinks were located in the midnight-dawn sector, in which the drift of ionospheric currents was predominantly driven by westward electrojets. …”

Predictive Capabilities and Limitations of Stream Interaction Region Observations at Different Solar Longitudes by R. C. Allen, G. C. Ho, L. K. Jian, G. M. Mason, S. K. Vines, D. Lario

“…Abstract Advanced warning of a stream interaction region (SIR) or corotating interaction region (CIR) impinging upon the magnetosphere of Earth is important for space weather forecasting, due to the ability of SIRs/CIRs to trigger geomagnetic storms and affect ionospheric composition and winds. However, a focused investigation of the likelihood that either an L5 monitor or Earth‐trailing “string‐of‐pearl” constellation of satellites would be able to serve as an effective warning buoy for SIRs/CIRs that will affect the near‐Earth space environment has yet to be extensively performed. …”

Auroral Drivers of Large dB∕dt During Geomagnetic Storms by Ying Zou, Caleb Dowell, Banafsheh Ferdousi, Larry R. Lyons, Jiang Liu

“…Abstract Forecasting geomagnetically induced currents (GICs) remains a difficult challenge, and open questions hindering our understanding include when and where GICs become large and what magnetospheric and ionospheric processes are responsible. This paper addresses these questions by determining the auroral drivers of large dB∕dt (>100 nT/min, a proxy for GICs) on the ground during geomagnetic storms. …”

Predictive Capabilities of Corotating Interaction Regions Using STEREO and Wind In‐Situ Observations by Yutian Chi, Chenglong Shen, Christopher Scott, Mengjiao Xu, Mathew Owens, Yuming Wang, Mike Lockwood

“…Abstract Solar wind stream interaction regions (SIRs) and corotating interaction regions (CIRs) can cause geomagnetic storms and change energetic particle environment, ionospheric composition on Earth. Therefore advanced warning of SIRs/CIRs is vital for mitigating the effect of space weather on critical infrastructures in modern society. …”

Multi‐Instrument Investigation of the Impact of the Space Weather Events of 6–10 September 2017 by Paul O. Amaechi, Andrew O. Akala, Johnson O. Oyedokun, K. G. Simi, O. Aghogho, Elijah O. Oyeyemi

“…Interestingly, the X.9.3 flare resulted in a stronger ionospheric response than the X8.2 flare. Furthermore, global TEC map showed a higher response in the African and South American longitude during the respective event. …”

Mapping a Magnetic Superstorm: March 1989 Geoelectric Hazards and Impacts on United States Power Systems by Jeffrey J. Love, Greg M. Lucas, E. Joshua Rigler, Benjamin S. Murphy, Anna Kelbert, Paul A. Bedrosian

“…Hazardous geoelectric fields were induced during different storm phases, at different local times, and, by inference, by a variety of ionospheric currents. Compared to geoelectric field amplitudes realized across the United States during March 1989, hazard maps used by utility companies to estimate systems exposure have much less geographic detail and a much smaller maximum‐to‐minimum range in geoelectric field amplitude. …”

ALGUNAS APLICACIONES RECIENTES DE LA TÉCNICA DE RADIO OCULTAMIENTO SATELITAL EN EL ESTUDIO DE PROCESOS ATMOSFÉRICOS by Alejandro de la Torre, Pedro Alexander, Pablo Llamedo, Rodrigo Hierro, Horacio Pessano, Andrés Odiard

“…From atmospheric profiles of refractivity and an atmospheric model, several parameters are obtained: from temperature (T), pressure, geopotential height and water vapor to minor species as aerosols, cloud liquid water and ionospheric electron density. The enormous advantage offered by the coverage in the whole planet, above the continental and oceanic territories, the 1K T resolution, the long term stability and mainly the absence of any restriction imposed by climatic conditions, makes the GPS RO technique unique among different remote sensing atmospheric systems. …”
