摘要
介绍了利用太阳辐射计-CE318近红外940nm水汽吸收通道反演水汽含量的两种方法-改进的Langley法和比值法.用改进的Langley法反演了2003年10月中旬合肥地区的水汽含量,并与气象预报的数值进行对比,其误差在10%以内.研究表明太阳辐射计是一种便携有效的水汽测量仪器.
Two methods of atmospheric column water vapor content retrieval from 940nm NIR and adjacent bands of CE318 sun photometer based on water vapor absorption in this region are introduced. They are respectively modified Langley Plot and ratio method. We use the modified Langley Plot to retrieve the atmospheric column water vapor content of Hefei region on mid October 2003. The comparison of the retrieved water column content using sun photometer with the weather forecast data shows that the error is less than ten percent. The study shows that sun photometer is a kind of instrument for effectively measuring the atmospheric column water vapor.
