Sentinel-5 Precursor Level 2 Cloud(L2__CLOUD_) |
|
The TROPOMI instrument onboard Sentinel-5 Precursor is a nadir-viewing, imaging spectrometer covering wavelength bands between the ultraviolet and the shortwave infrared. The instrument uses passive remote sensing techniques to attain its objective by measuring, at the Top Of Atmosphere (TOA), the solar radiation reflected by and radiated from the earth.
The TROPOMI instrument, single payload onboard Sentinel-5 Precursor, retrieves operationally the most important quantities for cloud correction of satellite trace gas retrievals: cloud fraction, cloud optical thickness (albedo), and cloud-top pressure (height). Cloud parameters from TROPOMI are not only used for enhancing the accuracy of trace gas retrievals, but also to extend the satellite data record of cloud information derived from oxygen A-band measurements initiated with GOME.
