Abstract:In view of the current lack of technical means for the calibration of visibility measuring instruments that meet the definition of visibility by the World Meteorological Organization,this paper proposes a 2700 K color temperature spectrum simulation method based on Gaussian spectrum model.According to the 2700 K color temperature spectrum simulation model,the engineering feasible Gaussian spectrum fitting unit full width at half maximum and peak wavelength combination are analyzed.The 2700 K blackbody color temperature spectrum is simulated by using a combination of a Gaussian spectrum fitting unit with a full width of 20 nm,a peak wavelength from 380 nm to 780 nm,and a peak interval of 20 nm.The simulation results provide technical support for establishing a calibration method for visibility measuring instruments that conforms to the definition of visibility defined by the World Meteorological Organization.
