Cameroon Advanced Measurements for Enhanced Observations of Water levels using Affordable GNSS-IR and Sentinel-3&6 Technology # CAMEO-WAGST **Cameroon Advanced Measurements for Enhanced Observations of Water Levels using Affordable GNSS-IR and Sentinel-3 & Sentinel-6 Technology** Project page (ESA EO AFRICA R&D Facility): eoafrica-rd.org Project PIs: Makan Karegar (University of Bonn), Loudi Yap (NIC) --- ## Contents - Overview - Key objectives - Repository scope - RPR sensor assembly and setup - Field campaign in Cameroon - GNSS-IR RPR data acquisition & processing - Altimetry FFSAR processing - Altimetry validation - Data access - Citation - License - Contact --- ## Overview This repository hosts the end-to-end processing workflow developed within the CAMEO-WAGST project funded by ESA (2024-2026). The goal of the project is to establish Africa's first GNSS-IR water level monitoring network and to use it for the validation of Sentinel-3A/B and Sentinel-6 satellite altimetry over rivers, estuaries and coastal zones in Cameroon. The workflow integrates: - Low-cost GNSS-IR water level monitoring using the Raspberry Pi Reflector (RPR) network - Satellite altimetry processing for Sentinel-3 and Sentinel-6 (including FFSAR focusing and retracking) - Validation and performance assessment of satellite water levels against GNSS-IR (RPR) observations and available in-situ river gauges The repository is designed to support reproducible research, open-source development and scalable deployment in data-sparse regions under the GNU General Public License v3.0 - see the LICENSE file for details. --- ## Key objectives of the CAMEO-WAGST project - Establish a cost-effective, low-maintenance monitoring infrastructure that can be implemented in developing countries to support operational early-warning systems for floods and droughts. - Contribute to an operational reference measurements production chain by providing continuous, high-quality reference data for the validation of Sentinel-3 and Sentinel-6 altimetry measurements over c …
