Belgium Aqualooks Experiment Multi-Look Water Observations

Multi-look remote sensing observations were collected to improve BRDF correction algorithms for coastal and inland waters. The dataset combines in-water fieldwork, above-water autonomous hyperspectral measurements from the PANTHYR-2 system, and satellite data from CHRIS-PROBA and Pleiades A/B sensors. It was produced by the OB_DAAC organization and last updated in March 2026.

Use Cases

• Developing and validating BRDF correction algorithms for satellite-derived water quality products.
• Characterizing the bidirectional reflectance distribution function (BRDF) of turbid coastal and inland waters.
• Calibrating radiative transfer models using multi-angle observations from water, above-water, and top-of-atmosphere perspectives.
• Studying the impact of skyglint and sunglint on remote sensing uncertainty in aquatic environments.

Strengths

• Integrates multi-platform observations including in-situ fieldwork, autonomous hyperspectral systems, and satellite sensors.
• Focuses on a specific, challenging problem (BRDF correction in turbid waters) with data collected during a dedicated 3-week field experiment.
• Cross-platform presence on NASA Earthdata and Data.gov signals its importance and curation.

Limitations

• Critical metadata such as row count, specific column names, and dataset size are unknown across all sources.
• Conflicting license information: one source lists 'other-license-specified' while another lists 'None'.
• The temporal coverage is implied but not explicitly stated, and the exact date range of the 2021 experiment is unspecified.
