2 GRAPE main objectives: Create and maintain distributed networks of specialized GPS/GNSS Ionospheric Scintillation and TEC Monitors Identify and quantify mechanisms that cause scintillation and control interhemispheric differences, asymmetries and commonalities Develop ionospheric scintillation climatology, tracking and mitigation models to improve prediction capabilities of space weather. Retrieve tropospheric PWV for input to weather forecast models and to develop regional PWV climatology for atmospheric sensing in remote areas.
3 GRAPE structure WG- Solar-Terrestrial interactions and ionospheric effects in the current solar-cycle (chair: Paul Prikryl- Canada, co-chair: Emilia Correia- Brazil) WG2-Lower atmosphere delay in GNSS based systems (chair: Monia Negusini Italy) WG3- Modelling and models testing (chair: Cathryn Mitchell UK, co-chair Marcin Grzesiak, Poland) WG4- GNSS Data management strategy.
