    "abstract": "The TROPOspheric Monitoring Instrument (TROPOMI) uses 4 different grating spectrometers covering 8 spectral bands in the range 270-2385 nm. The main aim for this instrument is observing atmospheric chemistry. TROPOMI will be able to detect many species in the atmosphere such as BrO, CH4, ClO, CO, CO2, H2O, HCHO, N2O, NO, NO2, NO3, O2, O3, O4, OClO, SO2 and aerosol. It scans using a push-broom technique with a swath of 2600km.",
