Welcome to GRAPE

GRAPE (GNSS Research and Application for Polar Environment) is a joint GeoSciences and Physical Sciences Expert Group lasting from 2012 to 2020. 

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, intensifying the efforts to build a robust network of collaborations in order to answer a variety of space weather related needs through ad hoc data sharing and model development.

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 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.

GRAPE White Paper on Atmosphere and Geospace, September 2020

The White Paper  Polar atmosphere and Geospace: Present knowledge, infrastructures and future research directions  is now downloadable at the SCAR Library. The White Paper will be soon published on the SCAR  Bulletin.

GRAPE on line worskhop

The GRAPE on line worskhop has been held via Google Meet 1-3 July 2020. The workshop has been followed by, on the average, 65 participants from all over the world that had the occasion to discuss on the future research direction of the Polar Atmosphere and Geospace.
