On the relation between radiation belt electrons and solar wind parameters/geomagnetic indices: Dependence on the first adiabatic invariant and L*
The relation between radiation belt electrons and solar wind/magnetospheric processes is of particular interest due to both scientific and practical needs. Though many studies have focused on thisExpand
Kp forecast models
[1] Magnetically active times, e.g., Kp > 5, are notoriously difficult to predict, precisely the times when such predictions are crucial to the space weather users. Taking advantage of the routinelyExpand
Solar, interplanetary, and magnetospheric parameters for the radiation belt energetic electron flux
[1] In developing models of the radiation belt energetic electron flux, it is important to include the states of the interplanetary medium and the magnetosphere, as well as the solar activity. InExpand


“Space weather forecast”: Prediction of relativistic electron intensity at synchronous orbit
Long-term variations in high-energy (greater than 2 MeV) electron flux at synchronous orbit are examined to reveal their close relationship to geomagnetic activity. The electron flux diminishesExpand
Highly relativistic magnetospheric electrons: A role in coupling to the middle atmosphere?
Long-term (1979-present) observations of relativistic electrons (2–15 MeV) at geostationary orbit show a strong solar cycle dependence. Such electrons were largely absent near the last solar maximumExpand
Highly relativistic electrons in the Earth';s outer magnetosphere: 1. Lifetimes and temporal history 1979–1984
Highly relativistic electrons (3–10 MeV) at times are observed to populate the earth's magnetosphere near the geostationary orbit (r ∼ 6.6 RE). Electron fluxes and energy spectra are shown which wereExpand
The antarctic ozone minimum: Relationship to odd nitrogen, odd chlorine, the final warming, and the 11‐year solar cycle
Photochemical calculations along “diabatic trajectories” in the meridional plane are used to search for the cause of the dramatic springtime minimum in Antarctic column ozone. Results indicate thatExpand
Magnetospheric Impulse Response for Many Levels of Geomagnetic Activity
The temporal relationship between the solar wind and magnetospheric activity has been studied using 34 intervals of high time resolution IMP 8 solar wind data and the corresponding AL auroralExpand
Space Charging Currents and Their Effects on Spacecraft Systems
The range and limits on the space charging electron currents available in the near-geosynchronous orbit have been identified from a large SCATHA satellite data base. The most intense currentExpand
Solar wind control of auroral zone geomagnetic activity
An empirical analysis of solar wind-magneto- sphere energy coupling functions is reported. Using the tech- nique of linear prediction filtering with 2.5 minute data, we examine the relationship ofExpand
The propagation of Jovian electrons to Earth
Jovian electron flux increases are observed by the University of Chicago experiment on the earth-orbiting satellite Imp 8 throughout five ∼13-month Jovian synodic years during the period from launchExpand
Do Jovian electrons influence the terrestrial outer radiation zone
Using energetic electron data (30 keV - 2 MeV) from instruments onboard spacecraft 1976-059A at synchronous orbit (6.6 RE), we have been able to study relatively long-term electron flux variations.Expand
Impulse response of geomagnetic indices to interplanetary magnetic field.
The impulse response of the geomagnetic indices (Dst, AL, AU and AE) to the interplanetary magnetic field southward component (IMF-Bz) is calculated on the assumption that the magnetosphere acts as aExpand
