Abstract:
Based on the data of several instruments applied in the 2014 Yangjiang and Tibetan experiments, the sensitivity, liquid water content (LWC or ice water content, IWC) can be detected and difference between different mode echoes of a new solidstate millimeter wave radar (SMMR) constructed by State Key Laboratory of Severe Weather (LaSW) and 23th Institute of Aerospace Science and Technology are contrasted. Also, difference between this radar and microrain radar (MRR) echo is contrasted. The results show: (1) differences between different modes of SMMR are in reasonable agreement with theoretical results. All the status and cumulus in nearsurface layer can be observed by boundary layer mode and precipitation mode. Cirrus mode can observe cirrus which ice water content is over 0.0007 g·m-3. Observation capability of all three modes decreased with the increase of height. (2) Differentials between three mode echoes are mostly less than 3.5 dB. (3) MRR echo and Pasivel2 laser optical disdrometer echo are almost same, system difference existed between MRR and SMMR echo.
