This international Chapman conference expands upon previous meetings on space weather in at least two ways:

  • Emphasis will be on the hemispheric and longitudinal dependence of the ionosphere and thermosphere response to major solar events.
  • Expansion of the study of space weather by examining the Earth system response during times when solar and geomagnetic activity are not so extreme; for instance plasma irregularities or “bubbles” can occur on any night even when geomagnetic activity is benign, and have a severe impact on satellite communication and GPS navigation.

The conference will have at least two broader objectives:

  • Assemble an international group of heliophysics scientists to plan and discuss current and needed observations at mid and low latitudes in the African longitude sector, a region that has never been explored in detail using ground-based instruments. In order to have a complete global understanding of equatorial ionosphere motion and take the global modeling effort one step forward, deployment of ground-based instruments in Africa is essential. Therefore, strong interaction between scientists from instrument donor and host institutes is crucial in order to have successful instrument deployment and continuous data retrieval process.
  • Enhance the space science education and research interest in the continent. The interaction between African and other international scientists will significantly spark interest in space science education and research throughout Africa. It will facilitate international collaborations, gain exposure in African universities, and encourage the next generation of African scientists to become inspired by space science. The conference will also provide ideal opportunities for African scientists and graduate students to communicate their scientific results to the international scientific community.

The conference will be focused on at least six main science themes: (1) Hemispherical Dependence of Magnetospheric Energy Injection and the Thermosphere-Ionosphere Response; (2) Longitude and Hemispheric Dependence of Storm-Enhanced Densities (SED); (3) Response of the Thermosphere and Ionosphere to X-Ray and EUV Time-History During Flares; (4) Quiet-Time Longitude Spatial Structure in Total Electron Content and Electrodynamics; (5) Temporal Response to Lower-Atmosphere Disturbances; and (6) Ionospheric Irregularities and Scintillations.
