中文摘要:
      本文讨论了地对空微波遥感时5毫米吸收带各通道间的相关性,对各种地对空温度反演方法进行了比较。并应用蒙特卡洛法和统计控制法进行了温度、水汽的联合反演,挑选了最佳反演通道,取得了较为满意的数值结果。
英文摘要:
      In this paper, the correlation of the channels in 5mm absorption band for ground-based microwave remote sensing is discussed and various methods for inverting temperature are compared. Sequentially, choosing optimal channels, samples of Beijing in summer and winter during 1970-1975 are tested numerically with both Monte Carlo method and statistical method for obtaining temperature and water vapour profiles. The rms errors for inverting temperature profiles are less than 1.5 K below 600 mb and 1.6 K below 700 mb in summer and winter respectively. The mean relative errors for nverting water vapour profiles are within 20% in the lower troposphere.
