    "abstract": "We report on the retrieval of directional sea-roughness (the full directional\nmean square slope, including MSS, direction and isotropy) through inversion of\nGlobal Navigation Satellite System Reflections (GNSS-R) and SOlar REflectance\nSpeculometry (SORES)data collected during an experimental flight at 1000 m. The\nemphasis is on the utilization of the entire Delay-Doppler Map (for GNSS-R) or\nTilt Azimuth Map (for SORES) in order to infer these directional parameters.\nObtained estimations are analyzed and compared to Jason-1 measurements and the\nECMWF numerical weather model.",
