GPS for Weather and Space Weather Forecast (GWSWF) is an Action Group endorsed by SCAR. It is a joint SSG-GeoScience and SSG-Physical Sciences Action Group.

NEWS

This Action Group has been upgraded in the more ambitius expert group named GRAPE (GNSS Research and Application for Polar Environment). The new website is under construction.
*********

The XXXII SCAR Open Science Conference will be held at Portland, OR, USA, July 13-25, 2012. Call for papers is open (deadline 15 February 2012). Please consider the opportunity to submit an abstract to the Session 28 dealing with the activities of the GWSWF group ( http://scar2012.geol.pdx.edu/themes.php ). The XXXII SCAR Local Organizing Committee together with the Association of Polar Early Career Scientists plan a variety of opportunities for early career scientists, from travel grants to workshops, and social functions.The first 200 students who submit and have an abstract accepted for the Open Science Conference will pay no registration fee.

Scientific Content

Because of the lack in GNSS high-rate sampling receiver coverage over polar regions, particularly in Antarctica, the Action Group will contribute to answering questions that are still open within the Sun-Earth interactions studies. Some of the current issues in scientific international debate of particular interest are:
  1. characterization of the cause-effect mechanisms driving the formation and evolution of ionospheric irregularities;
  2. distribution and evolution of precipitable water vapour in polar regions which play a key role in the characterization and evolution of global earth phenomena.

Poposed Scientific Objectives

  1. Encourage the establishment of a permanent network of GNSS receivers for a multi-purposes investigation over Arctic and Antarctica.
  2. Stimulate international collaboration addressed to bi-polar investigations particularly at conjugate regions.

Cross Cutting Issues

The POLENET (SCAR-Geosciences Standing Group) and ICESTAR – UAMPY(Upper Atmosphere Monitoring for Polar Year, SCAR-Physical Sciences Standing Group) communities are cooperating to achieve the following:
  1. Ionospheric imaging over Antarctica.
  2. Exchange of data and expertise for the application of tomography to other fields of interest for both communities (e.g. 3D water vapour reconstruction).
  3. Exchange of technologies to install and manage remote GPS stations.
  4. Possibility to host instruments in the polar stations represented by the two communities.
