S5P_L1B_RA_BD6_HiR: Sentinel-5P TROPOMI NIR Radiance Data

Sentinel-5P TROPOMI Level-1B radiance data provides calibrated spectral measurements from the near-infrared detector (675nm to 775nm). The product is generated by KNMI's processor and offers radiance, irradiance, and calibration data in netCDF-4 format. Starting August 6, 2019, the data features a high spatial resolution of approximately 5.5km at nadir.

Use Cases

• Calibrating atmospheric models based on near-infrared radiance measurements.
• Analyzing spectral signatures for trace gas detection using the UV-VIS, NIR, and SWIR wavelength bands.
• Monitoring changes in Earth's radiation budget using the provided irradiance and radiance products.
• Assessing instrument performance and viewing geometry using the included calibration and engineering data.

Strengths

• Data has a high spatial resolution of approximately 5.5km at nadir implemented from August 6, 2019.
• Product covers three specific spectral bands: UV-VIS (270-495nm), NIR (675-775nm), and SWIR (2305-2385nm).
• Version 3 includes updated Calibration Key Data and residual background correction.

Limitations

• Key metadata such as row count, file size, and specific column names are not provided on any platform.
• License information is inconsistent: 'other-license-specified' on datagov but 'None' on NASA Earthdata.
• The dataset's temporal coverage is ambiguous, referencing a change on August 6, 2019 but not providing a start date.
