S5P_L1B_RA_BD5: Sentinel-5P TROPOMI Near-Infrared Radiance Data

Sentinel-5P TROPOMI Level-1B radiance data for band 5 (NIR detector) provides calibrated spectral radiance and irradiance measurements from a nadir-viewing hyperspectral spectrometer. The instrument covers ultraviolet-visible, near-infrared (675nm to 775nm), and shortwave infrared wavelengths with a high spatial resolution of approximately 5.5 km at nadir implemented from August 6, 2019. This dataset is generated by the Koninklijk Nederlands Meteorologisch Instituut (KNMI) processor and is part of the European Space Agency's Copernicus Sentinel mission family.

Use Cases

• Calibrating atmospheric retrieval algorithms using the provided radiance and irradiance products.
• Analyzing near-infrared spectral signatures for atmospheric constituents based on the 675nm to 775nm wavelength coverage.
• Monitoring changes in instrument performance and viewing geometry using the included engineering and calibration data.
• Assimilating top-of-atmosphere radiance measurements into atmospheric models for weather and climate research.

Strengths

• Data originates from a dedicated satellite mission (Copernicus Sentinel-5P) with a state-of-the-art hyperspectral instrument (TROPOMI).
• Provides high spatial resolution radiance data at approximately 5.5 km at nadir from August 6, 2019 onward.
• Dataset is hosted on multiple authoritative platforms (NASA Earthdata, Data.gov), indicating established use and validation.

Limitations

• Critical metadata is missing: specific column names, dataset size, and row counts are not provided in any source.
• Sources conflict on the 'last updated' date, with one listing 2019-08-06 and others listing 2026-04-09, creating uncertainty about data currency.
• The license is ambiguously listed as 'other-license-specified' without explicit terms, requiring users to investigate further.
