<name>eSWua IONOWORLD tool: Long-term forecasting global TEC maps</name>
<description>
This collection contains the Long Term Forecasting maps of the ionospheric Total Electron Content (TEC) [1] on a global scale (latitudinal and longitudinal ranges of 87.5°S–87.5°N and 180°W–180°E, respectively). The vTEC is estimated 24 hours in advance every 2 hours on a grid of 2.5° X 5° (lat x long). The proposed model is implemented through an algorithm consisting of two separate parts, working in cascade. The first part, termed “Single point TEC forecasting”, focuses on the 24-h ahead prediction of vTEC on selected points of the globe and the second is based on the use of the NeQuick2 Model fed by the outputs of the single point vTEC forecasting with the goal to retrieve the so-called “effective R12” used to extend the vTEC forecasting 24-h in advance at a global level.
