摘　　要：利用 8 mm辐射计对 8月份几种天气情况 (晴、多云、阴 )进行观测实验 ,统计结果表明多云和阴天对 8mm辐射计的亮温有明显影响。利用辐射计观测的天空温度对云中液态水总量的变化进行了反演 ,同时计算了大气衰减及液态水总量 ,并对误差做了分析。The atmospheric radiant characteristics measured by 8mm radiometer had been introduced and analyzed for several kinds of weather (sunny,cloudy, overcast).The experiment shows that cloud has an obvious effect on the apparent temperature of atmosphere. The attenuation induced by cloud was computed. The inversion of the variety of liquid water content in cloud was computed.
