Some optical engineerings need real-time atmospheric parameter profiles to forecast atmosphere transmittance and atmospheric background radiation. It is not convenient and easy to obtain realtime atmospheric parameter profiles. A method was proposed to construct the atmospheric parameter profiles mode. The scale-coefficients at different heights were obtained based on the historical radiosonde-data and real-time ground-based data over years. Then the real-time atmospheric parameter profiles using the mode and the scale-coefficient were realized. Using Xiamen district as example, comparing the simulated profiles of temperature, pressure, water vapor density profiles and precipitable water vapor with the radiosonde profiles, the results show that the difference of temperature profile under troposphere is less than 2.5 K, the pressure doesn’t change much, the water vapor density profiles are identical with rediosonde profiles in clear days and the difference of precipitable water is less than 15%. The proposed method can be used in some research programs to obtain real-time atmospheric parameters profiles.
