中文摘要:
      本文研究了微波波段(λ=5mm-3.2cm)大气的衰减作用。用微波辐射计,根据太阳射电法和大气辐射法进行大气微波吸收值的测量,同时用探空记录计算大气微波吸收值,两者进行比较和分析它们的相关。本文研究了大气微波吸收值与大气总水汽含量或地面气象要素(如温度、比湿)之间的关系,提供预告大气微波吸收值的可能性,云层对于大气吸收值的影响,文中也作了讨论。
英文摘要:
      The characteristics of atmospheric attenuation in microwave band (λ=5 mm-3.2 cm) are studied.Experimental results from the measurements of atmospheric attenuation by using solar radiation method and atmospheric radiation method in Beijing are compared with values calculated from radiosonde data to analyze their dorrelativity. The relationship between the atmospheric microwave absorption and total water vapor content or surface meteorological factors (for example, temperature, specific humidity) are discussed. It reveals the possibility o,I prediction of atmospheric microwave absorption. Effects of cloud on attenualion are also described.
