STRIVE: A next-generation satellite mission to observe our changing atmosphere
STRIVE: A next-generation satellite mission to observe our changing atmosphere
The STRIVE mission pairs, for the first time, an infrared imaging spectrometer and a near-infrared multi-directional radiometer in one polar-orbiting platform. ALICE (Advanced Limb Infrared Chemistry Experiment) is a limb-scanning Dyson spectrometer observing infrared radiation emitted from the Earth's limb to retrieve profiles of atmospheric composition and temperature during day and night. ARGOS (Aerosol Radiometer for Global Observations of the Stratosphere) is a dual-wavelength limb profiling radiometer measuring backscattered solar radiation to retrieve aerosol properties during the day.
Observes infrared radiation (4.5-14.1 μm) emitted from Earth’s limb to retrieve profiles of temperature and atmospheric constituents (O3, H2O, CH4, N2O, CFC-11, CFC-12, CO, HCN, NO2, HNO3, ClONO2, N2O5; Cloud/Aerosol height, type, extinction)
