Sentinel-5P TROPOMI: Hyperspectral Radiance and Calibration Data

Sentinel-5P TROPOMI Level-1B data provides calibrated radiance and irradiance measurements from a satellite spectrometer covering ultraviolet-visible, near-infrared, and shortwave infrared wavelengths. The product is generated by the Royal Netherlands Meteorological Institute (KNMI) and includes calibration and engineering data in netCDF-4 format. Starting August 6, 2019, the data features an along-track high spatial resolution of approximately 5.5 kilometers at nadir.

Use Cases

• Calibrating atmospheric retrieval algorithms using the provided radiance and irradiance data.
• Analyzing instrument performance and viewing geometry based on the included engineering products.
• Studying spectral signatures across UV-VIS, NIR, and SWIR bands for different surface and atmospheric conditions.
• Comparing pre- and post-August 2019 data to assess the impact of the higher spatial resolution implementation.

Strengths

• Data is produced by an authoritative institution (KNMI) for the European Space Agency's Sentinel mission.
• Implements high along-track spatial resolution (~5.5 km at nadir) from August 6, 2019.
• Covers a broad spectral range across three distinct bands (UV-VIS, NIR, SWIR).

Limitations

• Key metadata such as row count, file size, and specific column names are unavailable across all platforms.
• License information is inconsistent, listed as 'other-license-specified' on one platform and null on others.
• The dataset's update history is unclear, with one source showing a 2026 date and others showing 2021 or null.
