S5P_L1B_RA_BD2: Sentinel-5P TROPOMI UV Band Radiance Data

Sentinel-5P's TROPOMI instrument provides high-resolution (~5.5 km at nadir) radiance measurements from a nadir-viewing, push-broom grating hyperspectral spectrometer. This Level-1B product, processed by KNMI, delivers calibrated radiance, irradiance, and engineering data for the ultraviolet detector band covering 270nm to 495nm. The dataset is part of the European Copernicus program, a joint initiative between ESA and the Netherlands.

Use Cases

• Calibrating atmospheric models based on ultraviolet-visible (UV-VIS) radiance measurements.
• Validating satellite instrument performance using the provided engineering and calibration products.
• Developing algorithms for trace gas retrieval from hyperspectral radiance data in the UV band.
• Studiating atmospheric scattering and absorption processes using spectral radiance across the 270-495nm range.

Strengths

• Provides high spatial resolution radiance data at approximately 5.5 km at nadir from a dedicated atmospheric monitoring satellite.
• Covers a specific and scientifically important spectral range (UV-VIS, 270nm to 495nm) with a hyperspectral instrument.
• Data is hosted on multiple authoritative platforms (NASA Earthdata, Data.gov), indicating established provenance and access.

Limitations

• Critical metadata is missing: no column names, row counts, or file sizes are provided in the input.
• The 'last updated' metadata conflicts between sources, with dates ranging from 2019-08-06 to 2026-04 09.
• The license is ambiguously listed as 'other-license-specified' without further details.
