【摘要】 本文选取了我国东部由南至北，纬度分布不同的12站点43个夏季晴空大气样点、8个云雨大气的样点，利用TOVS(极轨卫星垂直探测)资料及地面观测资料，使用中分辨率大气辐射传输模式MODTRAN3，讨论当时大气中的太阳和地气系统的辐射情况，计算当时大气中的太阳加热率、红外冷却率。 在对晴空大气的计算中，本文对太阳的直接辐射与地气系统的红外辐射状况进行了分析，并讨论在不同的大气状况下太阳加热率和红外冷却率的情况，找出与太阳加热率和红外冷却率变化相关较大的因子—太阳天顶角和水汽条件、纬度；本文还进一步分析了不同纬度样本的太阳加热率与红外冷却率日变化及有云、有雨情况下太阳加热率和红外冷却率的变化情况：另外，文中通过改变二氧化碳在大气中含量的方法，讨论了它对太阳加热率与红外冷却率的影响。将个别站点大气辐射情况与实测值进行了分析研究，并将本文的计算结果与前人的结论比较，发现利用卫星资料来计算当时大气辐射状况是基本可信的。 本文的结果较为真实地反映了夏季我国东部地区的早、晚太阳加热率与红外冷却率的状况，及部分影响因子改变时的当地太阳加热率与红外冷却率的变化情况。更多还原

【Abstract】 In this paper, the solar and land-atmosphere radiation rates are calculated by MODTRAN3 model and satellite observation as well as surface data, solar direct irradiance infrared irradiance solar heating rate and infrared cooling rate were calculated from 43 samples of sunshine day and 5 samples of cloudy day 3 samples of rainy day of different latitudes in 12 stations.The paper analyzed solar heating rate and infrared cooling rate in sunshine day, the factors such as zenith angle, water vapor and latitude were found out correlating with solar heating rate and infrared cooling rate. Solar heating rate and infrared cooling rate change on the same day and at the same station. When sky was cloudy and rainy, the infrared cooling rate was different form that on sunshine day. Further more, the effect of thickness of CO2 was discussed in this paper. Compared with the model output and the observation, the model result is reasonable.Analysis shows that the result of this paper reflected the solar heating and infrared cooling rates correctly in summer in east part of China, and the relation between the changing factors and local solar heating and infrared cooling.更多还原
