Short Summary

This paper describes the datasets and methodology used during a workshop to demonstrate the potential and challenges of Sentinel-2 L2A time series for monitoring soil moisture and inundated areas in grasslands and wetlands, without presenting statistically validated results.

Objective

• To illustrate the potential and challenges of using Sentinel-2 L2A time series data to monitor soil moisture and inundated areas in grasslands and wetlands.

Study Configuration

• Spatial Scale: Demervallei region in Flanders, Belgium, specifically the Webbekomsbroek area. Field survey points were collected with centimetre spatial accuracy.
• Temporal Scale: Sentinel-2 L2A time series data covered periods from 2020-01-01 to 2025-12-31. Field visits and survey point collection occurred on 2025-10-15 from 09:00 to 12:30.

Methodology and Data

• Models used: No specific hydrological or land surface models were used. The analysis involved a custom script (provided on GitHub) for processing Sentinel-2 L2A time series data.
• Data sources:
  • Sentinel-2 L2A time series data (bands B02, B03, B04, B05, B08, B8A, B11, B12, and SCL) downloaded from OpenEO using R.
  • Field survey points collected with a hand-held RTK corrected GPS using QField on a smartphone, providing centimetre accuracy. These points were manually labeled as 'Inundated open', 'Inundated semi', 'Inundated close', or 'Non-inundated'.

Main Results

• The study primarily served as a demonstration during a workshop, showcasing the application of Sentinel-2 data for inundation monitoring.
• Field survey points were collected and classified based on inundation status and vegetation cover, providing ground truth for illustrative purposes.
• No real statistical validation or quantitative results regarding soil moisture or inundated area accuracy were presented, as the data layers were used for demonstration only.

Contributions

• Provides a practical demonstration of using Sentinel-2 L2A time series for monitoring soil moisture and inundation in specific wetland and grassland environments.
• Offers open-source scripts and datasets (NetCDF Sentinel-2 time series, GeoPackage files for regions and survey points) for further exploration and analysis by the scientific community.
• Highlights the utility of combining satellite imagery with high-accuracy field observations for environmental monitoring.
