Other comments or informationNRT: 2018 - current. *Sentinel-5P's instrument called Tropomi (TROPOspheric Monitoring Instrument) is a spectrometer sensing ultraviolet (UV), visible (VIS), near (NIR) and short-wavelength infrared (SWIR) to monitor ozone, methane, formaldehyde, aerosol, carbon monoxide, NO2 and SO2 in the atmosphere. | |
