S5P_L1B_RA_BD8_HiR: Sentinel-5P TROPOMI Radiance and Calibration Data

Sentinel-5P TROPOMI Level-1B radiance product for band 8 (SWIR detector) provides calibrated radiance, irradiance, and engineering data from a hyperspectral spectrometer. The instrument covers ultraviolet-visible, near infrared, and shortwave infrared wavelengths (270nm to 2385nm) with a nadir spatial resolution of approximately 5.5km implemented from August 6, 2019. Data is generated by the Koninklijk Nederlands Meteorologisch Instituut (KNMI) processor and stored in netCDF-4 format.

Use Cases

• Calibrating atmospheric models using measured radiance and irradiance data.
• Monitoring instrument performance over time based on engineering and calibration products.
• Developing algorithms for trace gas retrieval from shortwave infrared (SWIR) spectral bands.
• Studying spatial and temporal variations in Earth's radiance at a ~5.5km nadir resolution.

Strengths

• Data originates from a dedicated European Space Agency (ESA) satellite mission, a joint initiative with the Kingdom of the Netherlands.
• Provides high spatial resolution (~5.5km at nadir) data from August 6, 2019, onwards.
• Covers a broad spectral range across ultraviolet-visible, near infrared, and shortwave infrared wavelengths.

Limitations

• Key metadata such as row count, file size, and specific column names are not provided across any source.
• Sources conflict on last update dates, with entries from 2021 and 2026, creating uncertainty about data freshness.
• The license is ambiguously listed as 'other-license-specified' without explicit terms.

Provenance

Source
