Greenhouse-gases Monitoring Instrument (GF-5)
Four-band NIR/SWIR greenhouse-gas spectrometer on GF-5 for CO2 and CH4 mole-fraction retrieval, using O2, CO2, and CH4 bands around 765, 1575, 1650, and 2050 nm.
The Greenhouse-gases Monitoring Instrument on GF-5 is a four-band NIR/SWIR passive optical spectrometer for carbon dioxide and methane retrieval. Its GF-5 configuration uses mechanical cross-track scanning with five cross-track samples, about 800 km swath, and 10.3 km sub-satellite-point resolution, giving global daylight coverage in five days [1]. The instrument observes oxygen, carbon dioxide, and methane absorption bands in the 759-2058 nm range, supporting pressure, cloud, and aerosol correction along with XCO2 and XCH4 retrieval [2]. The GF-5 instrument measures CO2 and CH4 profiles [1]. SWIR absorption greenhouse-gas screening is demonstrated on GF-5 [1].
