【Abstract】 The atmospheric spectral transmittance and background radiance have important applications in many research areas,such as atmospheric remote sensing,optical-electronical engineering,etc.Based on our algorithms of fast computation of atmospheric molecular absorptions,the aerosol extinction,and atmospheric multiple-scattering,a combined atmospheric radiative transfer(CART) software was developed.The CART was used to compute atmospheric spectral transmittance and background radiance from visible to far infrared wavelength range efficiently,the spectral resolution of the CART is 1 cm-1.The algorithms,the computation functions,and some calculating examples of the CART were introduced.Some experimental results for the validation of the CART were also shown.CART could be used in many fields such as atmospheric transmittance correction for target radiative characteristics measurements,the design and performance evaluation of optic-electronic devices,etc.更多还原
