Raw shortwave-infrared light measured (Sentinel-5P)

Sentinel-5P TROPOMI Radiance product band 8 (SWIR detector) L1B 5.5km x 7km V3 (S5P_L1B_RA_BD8_HiR) at GES DISC
atmosphere NASA GES_DISC Level 1B active
In plain English

What it measures. Raw, calibrated readings of how much shortwave-infrared light the sensor recorded (radiance) in one specific detector band, before any of it is turned into pollution or surface maps.

How it's made. Produced from the TROPOMI instrument on Europe's Sentinel-5P satellite at its lowest processing level, where the raw signal is calibrated and geolocated but not yet interpreted.

How & where you'd use it. A building-block input that scientists feed into higher-level products; most people use the downstream pollution and gas maps rather than this raw light-measurement file directly.

Official description

Starting with version 3, Calibration Key Data (CKD) have been updated. 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_BD8_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.
