Calibrated raw shortwave-infrared light measurements (Sentinel-5P, band 7)

Sentinel-5P TROPOMI Radiance product band 7 (SWIR detector) L1B 5.5km x 7km V2 (S5P_L1B_RA_BD7_HiR) at GES DISC
atmosphere NASA GES_DISC Level 1B
In plain English

What it measures. Calibrated readings of how much shortwave-infrared light the sensor recorded in one specific band, for individual scenes. These are basic light measurements, not yet turned into pollution or gas amounts.

How it's made. Recorded by the TROPOMI instrument on Europe's Sentinel-5P satellite and processed to an early, calibrated stage (Level 1B) by the Dutch meteorological institute.

How & where you'd use it. A building-block input that scientists feed into algorithms to derive air-quality and trace-gas products; most people use those higher-level results rather than this raw light data 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_BD7_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.
