In terms of the atmospheric transmittance spectra for radiation and the relationship among the relative temperature measurement sensitivity, the temperature resolving power and the working wavelength, the working wavelength of this instrument is determined. 从系统的相对测温灵敏度及探测器的温度分辨率与波长间的关系出发,结合大气对红外辐射的透射特性,确定了系统的工作波长;
With measured data, this paper puts forward a modified downward atmospheric radiation assessment model based on Iziomon ( 2003 )'s model and the measurement information. A better match between the estimation value and the actual measured value is achieved. 本文依据实测资料,对Iziomon(2003)昙天大气下行辐射估算模型进行修正,修正后的模型估算值与实测值非常接近。
Atmospheric aerosols play an important role in atmospheric radiation balance through absorb and scatter the solar radiation, which changes local weather and global climate. Accurate measurement is highly requested to estimate the radiative effects and climate effects of atmospheric aerosol. 大气气溶胶通过吸收和散射太阳辐射影响大气辐射平衡,它对全球及局部地区的气候变化具有重要作用,因此精确测量大气气溶胶的光学特性对评估其辐射效应和气候效应的具有重要意义。
