摘要:

以美国国家环境预报中心(NCEP)提供的 FNL资料作为研究对象,对该资料的特点、包含内容、解码以及使用方法做出介绍。以Visual C++6.0为编程工具,开发针对FNL资料的数据分析程序,提取温度、气压、臭氧等气象和大气分子参数。结果表明FNL资料具有较高的可信度,可以为场地定标提供部分参数输入。基于数据分析结果,实现瑞利散射光学厚度、水汽含量和臭氧吸收光学厚度计算等方面的应用。提出下一步的研究方向。

Abstract:

Due to the need of meteorological parameter in remote sensor calibration procedure, National Centers for Envirionmental Prediction (NCEP) FNL data is adopted as the source of meteorological information. The characteristics, involving information, decoding and application algorithms of FNL data are introduced. A FNL data processing and analysis code is programmed based on VC++6.0 on Windows operationing system through which the meteorological parameters like temperature, pressure and ozone of a corresponding calibration site are analyzed. It is proved that the results are of high reliability that could be used as the input parameters of calibration. Rayleigh optical depth, water vapor and ozone optical depth are calculated based on the results. The next direction of investigation is outlined.
