Welcome to GRAPE

The International Polar Year (IPY) and International Heliophysical Year (IHY) initiatives left an important heritage in terms of data sharing, expertise exchange and increasing awareness of the current scientific capabilities. In particular, the GWSWF SCAR Action Group took advantage of the Interhemispheric Conjugacy Effects in Solar-Terrestrial and Aeronomy Research (ICESTAR) and the Polar Earth Observing Network (POLENET) experiences that lead to .....

Main Objectives

- Create and maintain distributed networks of specialized GPS/GNSS Ionospheric Scintillation and TEC Monitors particularly at high latitudes.
- Identify and quantify mechanisms that cause scintillation and control interhemispheric differences, asymmetries and commonalities in scintillation occurrence and intensity as a result of the geospace environment conditions.
- Develop ionospheric scintillation climatology, tracking and mitigation models ....


Announcement: the 2018 school "Polar Upper Atmosphere: from Science to Operational Issues", will be held at the International School of Space Science in L'Aquila, Italy, on 17-21 September 2018. Some financial support is available for a limited number of students. Applications, including a brief curriculum vitae, should be made through the school website's application page.
