微波遥感低空大气温度层结的研究

STUDIES ON THE GROUND-BASED MICROWAVE RADIOMETER AND ITS MEASUREMENTS OF THE LOWER ATMOSPHERIC TEMPERATURE PROFILES

摘要: 根据大气噪音谱,用接收5mm微波噪音,遥感低空大气温度层结。研制了5mm微波辐射计(C型机v=54.4 Gc)。在野外实验中与无线电探空仪对比,在3km以下,温度层结偏差2—3°K。为了能够在云天情况下遥感大气温度层结,研制了8mm微波辐射计,并进行了接收大气噪音的实验。

Abstract: We constructed 5 mm-radiometer (C-type 54.4 Gc).Using the reception of 5 mm atmospheric nose, the temperature profile in the lower atmosphere was obtained.In the field test, as compared with radiosonde, the mean temperature deviation was 2-3 K below 3 km. For the remote sensing temperature profile in cloudy sky,we constructed 8 mm radiometer (35.3 Gc) and it was used in measurement of atmospheric noise.
