S5P_L1B_RA_BD2_HiR: Sentinel-5P TROPOMI Level-1B Radiance Data

Sentinel-5P's TROPOMI instrument is a nadir-viewing hyperspectral spectrometer with a 108-degree field of view, capturing data across ultraviolet-visible, near-infrared, and shortwave infrared wavelengths. Its Level-1B product provides calibrated radiance, irradiance, and engineering data, with a spatial resolution of approximately 5.5 km at nadir implemented from August 6, 2019. This dataset is processed by the Royal Netherlands Meteorological Institute (KNMI) using a netCDF-4 enhanced model.

Use Cases

• Calibrating atmospheric models based on hyperspectral radiance and irradiance measurements.
• Analyzing spatial patterns of atmospheric radiation using the instrument's 5.5 km nadir resolution.
• Validating satellite sensor performance using the included calibration and engineering products.
• Tracking changes in atmospheric data quality following the implementation of dynamic straylight correction in version 3.

Strengths

• Data incorporates specific processing improvements, including dynamic straylight correction and updated Calibration Key Data starting with version 3.
• Provides measurements across three distinct spectral ranges: UV-VIS (270-495nm), NIR (675-775nm), and SWIR (2305-2385nm).
• Cross-platform presence on NASA's GES DISC and Data.gov signals its importance and established use in the scientific community.

Limitations

• Critical metadata is missing: row count, file size, and a complete column schema are not provided.
• License information is inconsistent, listed as 'other-license-specified' on one platform and null on another.
• The dataset's temporal coverage is ambiguous, referencing a change on August 6, 2019, but lacking a clear start or end date.
