S5P_L1B_IR_SIR: Sentinel-5P TROPOMI SWIR Irradiance Data

Sentinel-5P's TROPOMI instrument is a hyperspectral spectrometer with a 108-degree field of view, measuring ultraviolet to shortwave infrared light. Its Level-1B product provides calibrated radiance and irradiance data from the shortwave infrared module, processed by the Royal Netherlands Meteorological Institute. This dataset supports atmospheric science by delivering fundamental measurements for deriving trace gas concentrations.

Use Cases

• Calibrating atmospheric models based on shortwave infrared (SWIR) radiance measurements.
• Deriving trace gas concentrations using the fundamental UV-VIS, NIR, and SWIR spectral data.
• Validating satellite sensor performance through engineering and calibration product analysis.
• Studying radiative forcing and scattering by analyzing atmospheric radiation data across multiple spectral bands.

Strengths

• Data originates from a dedicated European Space Agency mission with a sophisticated hyperspectral instrument.
• Processing is performed by an authoritative meteorological institute (KNMI).
• Covers a broad spectral range from 270nm to 2385nm across three distinct modules.

Limitations

• Critical metadata is missing: column names, row counts, and dataset size are not provided.
• License is ambiguously listed as 'other-license-specified' without clear terms.
• One source lists a last update date of 2026-04 09, which appears to be a future or placeholder date, conflicting with other sources showing 'None'.
