中文摘要：
有效辐射是地-气系统之间能量交换的重要形式之一.研究将遥感数据代入到经验公式中,达到经验公式和遥感反演资料的结合,实现了2001年中国全年、逐月有效辐射的空间化模拟.研究表明：模拟结果空间分布规律以及局地规律,均与中国很多已报道的研究结果相符合.通过与NCEP再分析资料的对比,发现模拟结果反映的宏观趋势与NCEP再分析资料的相似.尤其是在局部上,模拟结果对于有效辐射的还原度更好.
英文摘要：
It is an important form of the energy exchange of earth - atmosphere system. This paper has com- bined empirical equation method with directly retrieve method by using remotely sensed data by introducing remotely sensed digital product to calculate several parameters that will be used in the empirical equation based on empirical equation method. The spatial simulation of yearly and monthly effective radiation in 2001 was accom- plished. The regular pattern of spatial distribution of estimation result and the characteristics reflected by certain areas in estimation result are akin to many researchers＇ results. After the comparison between NCEP reanalysis data and estimation result,we have found that the macroscopical trend reflected by the former and the latter are the same;but estimation result can better express regional details than NCEP reanalysis data do.
