Several kinds of spectral calibration technologies are introduced in detail, including the spectrum lamp spectral calibration, mono-chromator spectral calibration, tunable laser spectral calibration, and the gas cell spectral calibration. The experimental principle, experimental methods and technical characteristics of different spectral calibration technologies are described by analyzing and comparing foreign high spectral remote sensors for trace gases. Based on the characteristics of ultra-high resolution spectral calibration for atmospheric remote sensors, it points out that the bandwidth of calibration equipment should reach the level of 0001 nm. It also suggests that the calibration method of improving optimization algorithm and comprehensive calibration methods should be considered to ensure the high spectral calibration accuracy of high spectral remote detectors for trace gases.
