SARTRAM: Sentinel-1 and Sentinel-2 Data for Peatland Water Table Depth Monitoring

29 restored peatlands and 98 water table depth logging sites in Scotland and Lithuania were monitored using Sentinel-1 and Sentinel-2 data. The dataset, created by Laurynas Jukna and last updated in April 2026, evaluates the SAR trapezoid model (SARTRAM) against optical and backscatter methods for predicting water table depth. It contains 189.8 MB of data in TIF, TIFF, JPEG, and XLSX formats.

Use Cases

• Comparing SAR-based and optical remote sensing models for water table depth prediction based on the described trapezoid model concept.
• Evaluating the performance of different value extraction methods (e.g., best-pixel, buffer averages) for satellite data in ecological monitoring.
• Applying temporal filtering techniques to improve the correlation of SAR data with ground measurements, as demonstrated with the moving average window filter.
• Monitoring the hydrological status of restored peatlands across different geographic regions using Sentinel-1 and Sentinel-2 time series.

Strengths

• Includes data from 29 restored peatlands and 98 specific monitoring sites, providing a multi-site evaluation.
• Compares five different model value extraction methods and applies a moving average window filter, showing a 10–19% improvement in correlation.
• Reports specific performance metrics, such as Spearman correlation coefficients up to 0.85 for the optical model and 0.65 for the SAR model.
• Uses dual-source satellite data from both Sentinel-1 (SAR) and Sentinel-2 (optical) missions.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for certain analytical tasks.
