Introduction of GF-5 Satellite and Ability of Monitoring NO 2 and O 3 Column Density from EMI

GF 5 is a hyperspectral imaging satellite which is configured with six forms of payloads. EMI is the first high-resolution imaging spectrometer used for the detection of atmospheric trace gases, the indicator of environmental pollution. The high spatial-temporal pollutants distribution information collected by EMI will assist government’s decision-making and evaluation of air quality guarding in the future.
