Calibrated raw light measurements (Sentinel-5P, near-infrared)
What it measures. Calibrated measurements of how much near-infrared light the sensor recorded, before it has been turned into pollution or other geophysical products. It also includes sunlight reference and calibration data.
How it's made. Produced from the TROPOMI spectrometer on the Sentinel-5P satellite, taking the rawest sensor output and applying calibration to make a 'Level-1B' product at about 5.5 km detail.
How & where you'd use it. A building-block input most people use indirectly through higher-level air-quality products rather than working with directly.

Official description
Starting from August 6th in 2019, Sentinel-5P TROPOMI along-track high spatial resolution (~5.5km at nadir) has been implemented. For data before August 6th of 2019, please check S5P_L1B_RA_BD5_1 data collection. The Copernicus Sentinel-5 Precursor (Sentinel-5P or S5P) satellite mission is one of the European Space Agency's (ESA) new mission family - Sentinels, and it is a joint initiative between the Kingdom of the Netherlands and the ESA. The sole payload on Sentinel-5P is the TROPOspheric Monitoring Instrument (TROPOMI), which is a nadir-viewing 108 degree Field-of-View push-broom grating hyperspectral spectrometer, covering the wavelength of ultraviolet-visible (UV-VIS, 270nm to 495nm), near infrared (NIR, 675nm to 775nm), and shortwave infrared (SWIR, 2305nm-2385nm). TROPOMI Level-1B (L1B) product is generated by the Koninklijk Nederlands Meteoroligisch Instituut (KNMI) TROPOMI L01B processor from Level-0 input data and auxiliary data products with the netCDF-4 enhanced model. It provides users with radiance, irradiance, calibration and engineering products.
