# Dataset Description

This dataset contains CYGNSS satellite GNSS-R observation data during the "Symphony" ship oil spill incident on April 30, 2021. The dataset is specifically designed for marine oil spill detection and oil film thickness estimation tasks, containing Delay-Doppler Map (DDM) observation data from 8 CYGNSS satellites throughout the day.

**Each NetCDF file contains:**
1. Raw DDM images: Power measurements of delay-Doppler matrix

2.Bistatic radar cross-section: Sea surface scattering characteristics

3.Geometric parameters: Satellite positions, incidence angles, reflection point coordinates, etc.

4.Timestamps: Precise observation time information

5.Quality flags: Data quality control parameters
