The GNSS (Global Navigation Satellite System) Research and Application for Polar Environment (GRAPE) aims to build and coordinate a robust network of international collaborations to address a variety of weather and space weather related needs at high latitudes and the polar regions (Arctic and Antarctica), through ad hoc data sharing and models development.
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 creation of working groups on specific themes such as the use of geodetic data to study weather and space weather events. The multidisciplinary approach of IPY is the key in overcoming relevant difficulties, above all, the poor coverage of Antarctica. GRAPE Expert group intend to continue to follow this route.
