GRAPE (GNSS Research and Application to Polar Environment) SCAR Expert Group Activity

Abstract:

With the aim of tackling the polar atmosphere and its effects on Global Navigation Satellite System (GNSS) especially under geospatial perturbed conditions or Space Weather events, GRAPE (GNSS Research and Application for Polar Environment) was established in 2012 as an Expert Group of SCAR (Scientific Committee on Antarctic Research). GRAPE (www.grape.scar.org), dealt with the monitoring and investigation of the bi-polar neutral and ionized atmosphere, by encouraging the establishment of a permanent network of GNSS receivers for multi-purposes investigations over the Arctic and Antarctica and by involving international efforts within the topic of solar terrestrial interactions and space weather. The main activities of GRAPE are presented to stimulate discussions and to encourage scientists and research groups to participate in the future actions leading to a possible new Proposal Planning Group of SCAR, titled RESOURCE- Radio Sciences Research on AntarCtic AtmosphEre.
