“…The ozone in the atmosphere is mainly concentrated at an altitude of 20-50 km, and the content of methane is low. Therefore, water vapor and carbon dioxide are dominant in the absorption of infrared radiation in the troposphere [26]. Generally, the amount of water vapor in the atmosphere is expressed by the amount of precipitation.…”

Aiming at the problem wherein temperature inversion accuracy is unstable due to the major differences in atmospheric transmittance under various observation paths, a method for measuring radiation characteristics of an aircraft engine’s hot parts and skin using a cooled middle-wave infrared camera is proposed. Based on the analysis of the aircraft’s infrared radiation characteristics, the atmospheric transmission model of any observation path was revised, the absolute radiation correction model was established, and the temperature inversion equation was calculated. Then, we used the quasi-Newton method to calculate the skin temperature and discussed uncertainty sources. After the theoretical study, an outfield test was carried out. A middle-wave infrared camera with a wavelength of 3.7–4.8 μm was applied to the actual experimental observation of the turbofan civil aviation aircraft. The ground observation distance was 15 km, and the flying height was 3 km. When implementing temperature inversion with the method presented in this paper, the surface temperature of the aircraft engine hot parts was 381 K, the correction uncertainty was ±10 K, the surface temperature of the skin was 296 K, and the correction uncertainty was ±6 K. As the experiment showed, the method in this paper can effectively implement infrared target temperature inversion and provide a reference for the quantification of infrared data.

“…Several mathematical models of ground vegetation canopy were developed in the field of climatology (Deardorff, 1978;Zhang, 1997) and were later adapted to simulate the thermal effects of plants in green roofs (Alexandri, 2007;Djedjig, 2012;Sailor, 2008). Such models should be able to dynamically simulate the effect of plants on the facade thermal performance for variable plant characteristics, facade properties, building orientations, and weather conditions.…”
