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

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.
