线性统计温度剖面反演从天底被动118-GHz O/分2/光谱表现出使用时间和空间一致的微波观测和无线电探空仪配置文件。单独的检索证明了冬季和夏季中纬度条件下，在晴朗的空气在陆地上，在白天和夜间的观测。检索算子是一个线性统计最小均方误差估计。一个纯粹的统计反演操作员规避辐射传输模型的不确定性和偏差的无线电探空仪或毫米波温度探测器数据的影响。无论是冬季还是夏季对流层，反演的廓线均方根误差约为0.7-1.2 K。>
Linear statistical temperature profile retrievals from nadiral passive 118-GHz O/sub 2/ spectra are demonstrated using time- and space-coincident microwave observations and radiosonde profiles. Separate retrievals are demonstrated for winter and summer midlatitude conditions in clear air over land; observations during both day and night are included. The retrieval operator is a linear-statistical minimum mean-squared-error estimator. A purely statistical retrieval operator circumvents the effects of radiative transfer model uncertainties and biases in either the radiosonde or Millimeter-wave Temperature Sounder data. The retrieved profile rms errors are approximately 0.7-1.2 K for either the winter or summer tropospheres. >
