JWG C.5: Exploitation of ground-based GNSS InterferometricReflectometry for climate applications

Introduction

GNSS Interferometric Reflectometry (GNSS-IR) is a relatively new ground-based remote sensing technique based on reflected GNSS signals. It has been used to measure water levels, snow accumulation, permafrost melt, soil moisture, vegetation water content, and significant wave height. With the increased numbers of GNSS-IR developers and users, there is a need for community based resources. Our group will focus on expanding and improving the existing open source software for both geodetic and low-cost GNSS-IR sensors, archiving locations of GNSS-IR sensors, and supporting new users. Validation datasets will be archived to allow new users to develop the needed skills to install and operate GNSS-IR sites and to analyze the data from the sites.

Objectives

  • Technical improvements of GNSS-IR models
  • Maintain/create inventory of GNSS-IR sites that have been used to measure climate variables
  • Guidelines for installing good GNSS-IR sites
  • Develop and maintain low-cost GNSS-IR sensor hub
  • Upgrade and maintenance of open source software/tools and use cases
  • Operational showcasing initiative for (near) real-time monitoring of climate variables
  • Sponsor software classes

Program of Activities

  • We schedule bi-monthly meetings that alternate between member meetings and online GNSS-IR webinar series every other session
  • Organizing sessions in international conferences and ICCC workshops
