摘要: 针对近年来利用卫星和地面常规资料估算向下长、短波辐射研究参数化方案, 对国内外研究进展进行综述。在综合分析有关文献的基础上, 介绍向下短波和长波辐射参数化方案的理论背景, 按照晴空和有云条件, 分别对辐射参数化方案进行总结, 并对这些方法在实际应用中的优缺点予以评述。晴空条件下, 向下短波参数化方案以统计和辐射传输模式为主, 长波辐射参数化方案以单、双参数法为主。有云条件下的辐射参数化方案则主要受限于云量的确定。地表向下短波和长波辐射的计算的局限性在于, 需要根据所能获取的地面气象观测资料、地表覆盖类型和卫星遥感数据, 选择合适的参数化方案。将来, 有发展前景的方法为极轨卫星和静止卫星遥感数据结合研究估算方案。

Abstract: Research progresses in parameterization schemes for estimating downward shortwave and longwave radiations are reviewed by use of satellite data and ground-based routine observations in recent years. Based on a comprehensive analysis of the relevant literatures, the theoretical backgrounds of downward shortwave and longwave radiation parameterization schemes are described. According to the clear-sky and cloudy-sky conditions, the radiation parameterization schemes are summarized and their advantages and disadvantages in the practical application are reviewed. Under clear-sky conditions, the main parameterization schemes of downward shortwave radiation are statistical methods and radiative transfer models; the longwave radiation parameterization schemes are mainly single-parameter and dual-parameter methodologies. Under cloudy-sky conditions, radiation parameterization schemes are mainly limited to the determination of cloudiness. The limitations of estimating downward shortwave and longwave radiation on the surface are the selections of appropriate parameterization scheme that need considering land cover types and the attainment of meteorological observations and satellite remote sensing data. In the future, the relatively promising estimation approach is pointed out by combination of polar-orbiting and geostationary satellite remote sensing data.

Key words: downward shortwave radiation, downward longwave radiation, parameterization schemes
