S5P_L1B_RA_BD1_HiR: Sentinel-5P TROPOMI UV Band Radiance

Sentinel-5P's TROPOMI instrument is a nadir-viewing hyperspectral spectrometer covering ultraviolet to shortwave infrared wavelengths. Its Level-1B product provides calibrated radiance and irradiance data, with a spatial resolution of approximately 5.5 km at nadir implemented from August 6, 2019. The data is processed by the Koninklijk Nederlands Meteorologisch Instituut (KNMI) and includes dynamic straylight and residual background corrections starting with version 3.

Use Cases

• Calibrating atmospheric models using radiance and irradiance products.
• Validating satellite instrument performance via engineering data.
• Analyzing time-series of Earth's atmospheric radiation across ultraviolet, visible, and infrared spectra.
• Supporting retrieval algorithms for trace gases based on hyperspectral radiance measurements.

Strengths

• Implements high spatial resolution (~5.5 km at nadir) along-track from August 6, 2019.
• Includes version 3 improvements: dynamic straylight correction and updated calibration key data.
• Covers a broad spectral range from ultraviolet-visible (270-495nm) to shortwave infrared (2305-2385nm).

Limitations

• Key metadata such as row count, file size, and specific column names are unavailable across all sources.
• Data before August 6, 2019, requires a different collection (S5P_L1B_RA_BD1_1), indicating a version discontinuity.
• License is specified only as 'other-license-specified' without detailed terms.
