Ionosphere function
Web22 jul. 2014 · The ionosphere is divided into cells and the STEC data are gathered from ground receiver networks. The use of large and dense receiver networks observing the maximum number of GNSS satellites is necessary to obtain a better scanning of the ionosphere in terms of spatial and temporal resolutions. WebIonosphere: The electron density field is provided from a climatological model, the latest version of the International Reference Ionosphere (IRI) (http://iri.gsfc.nasa.gov/), and Earth's magnetic field is provided from the 12th generation of the International Geomagnetic Reference Field (IGRF) (http://www.ngdc.noaa.gov/IAGA/vmod/igrf.html).
