Abstract

This dataset contains GNSS observations collected along the Río Petrohué in southern Chile during December 2023 and January 2024. The data were gathered as part of a field campaign supporting the validation of the SWOT (Surface Water and Ocean Topography) satellite mission. GNSS receivers were used to measure water surface elevation (WSE) at multiple locations along the river during SWOT overpasses.

The resource includes raw GNSS files in .sbf format and associated metadata. These observations are intended to support analyses of river slope and discharge estimation in steep, fast-flowing river systems. This dataset is useful for hydrologic studies and for evaluating the performance of SWOT in mountainous terrain.
