2024 Short Course on GNSS-IR for Water Level Measurements


Dates / Times: March 6 / 7    12:00-14:00 CET

Format: virtual

Sponsor: Collaborative Research Centre 1502 DETECT,


Software Requirements: python 3.9 running on Linux/MacOS
or the ability to install a docker

Registration deadline: February 26, 2024


Course Description:

GNSS Interferometric Reflectometry (GNSS-IR) is a ground-based environmental sensing method. It uses GNSS signals that have been reflected from the surface below the antenna. GNSS-IR has been used to measure soil moisture, snow accumulation, permafrost melt, vegetation water content changes, water levels, and significant wave heights.

The gnssrefl software was written to support GNSS-IR users. This short course will focus specifically on measuring water levels with GNSS-IR. The first day will present an overview on the basic principles of GNSS-IR and how to install and run the gnssrefl software. The second day will focus on models needed to measure water levels with GNSS-IR and examples using gnssrefl to measure water levels in lakes, rivers, and the ocean.

Short Course Instructors:
Kristine M. Larson (Uni Bonn DETECT)
Simon Williams (National Oceanography Centre)
Felipe Nievinski (Uni. Federal do Rio Grande do Sul)


The gnssrefl software is hosted at github:
