摘要
利用地基双通道微波辐射计(23.8和31.65GHz)所测量的大气辐射亮温以及地面的大气温度,湿度和压强测量值,给出了一种反演大气温度和水汽密度剖面的非线性回归算法,并利用郑州地区的历史探空资料进行仿真验证,结果表明非线性回归算法较线性回归算法具有更好的大气剖面反演精度。
Based on the surface meteorologic parameters and the brightness temperatures measured by ground-based dual-channel radiometer working at 23.8 GHz and 31.65 GHz, a non-linear regression method to retrieve temperature and water vapor density profiles is developed. With the historical radiosondes data of Zhengzhou, the simulations are obtained and show that the non-linear retrieval method has better retrieved accuracy than the linear one.
