S5P_L1B_RA_BD8: Sentinel-5P TROPOMI SWIR Radiance Data

Sentinel-5P TROPOMI Level-1B product provides calibrated radiance, irradiance, and engineering data from the TROPOMI hyperspectral spectrometer. The instrument covers ultraviolet-visible, near infrared, and shortwave infrared wavelengths, with a nadir spatial resolution of approximately 5.5 km implemented from August 6, 2019. This dataset is a joint initiative between the European Space Agency and the Kingdom of the Netherlands, processed by the Koninklijk Nederlands Meteorologisch Instituut.

Use Cases

• Calibrating atmospheric models based on SWIR band radiance measurements.
• Monitoring trace gases and aerosols using hyperspectral UV-VIS, NIR, and SWIR data.
• Validating satellite instrument performance using the provided engineering products.
• Analyzing spatial patterns of atmospheric radiation at a ~5.5 km nadir resolution.

Strengths

• Provides data from a hyperspectral spectrometer covering three distinct spectral bands (UV-VIS, NIR, SWIR).
• Offers a high spatial resolution of approximately 5.5 km at nadir for data from August 6, 2019 onward.
• Is a product of a joint international mission (ESA and the Kingdom of the Netherlands) and processed by a recognized institute (KNMI).

Limitations

• Column names and specific data structure are unknown across all platform descriptions.
• Platforms provide no information on dataset size (rows, file size), making scale assessment impossible.
• One source lists a last update date of 2026-04-09, while another lists 2019-08-06, indicating a potential conflict in metadata freshness.
