中文摘要
全球辐射能量是全球气候形成和变化的基本驱动力,而地球表面(陆表及海面)净辐射是辐射能量平衡系统中最重要的一个参量。针对现有卫星净辐射估算算法及产品普适性有限、过于依赖实测数据、高纬地区精度太差、时空分辨率不够、以及海面净辐射尚未有遥感算法等系列问题,本项目拟基于遥感及其它多源数据进行净辐射估算的基础性的问题进行四个方面深入研究:(1)在分析现有算法的适用性和不足的基础上,继续发展基于短波辐射直接估算净辐射的机器深度学习的统计模型;(2)基于大气层顶卫星观测资料,探索直接估算地表净辐射的新方法;(3)发展海面净辐射遥感估算混合方法的研究;(4)探讨地表”点”观测与粗糙像元净辐射数值的空间尺度转换关系。
英文摘要
Surface net radiation, which includes land and ocean surfaces net radiation, is the foundation for studies of global environmental and climate changes. Estimation of surface net radiation that characterizes surface radiation budget has been a challenging topic in the world for a long time, for example, the performance of the empirical model is heavily rely on the quality and quantity of the measurements, the tempo-spatial resolutions of the popular net radiation products cannot meet the needs of various scientific researches and applications, the lack of the ocean net radiation estimation methods based on remote sensing data, and so on. Based on the results of analyzing the existed net radiation estimation algorithms and products, a series of advanced new models based on remotely sensed data and other multi-sources ancillary information will be proposed in this project. The new developed models will included the empricial models and the hybrid models..After validating agai nst the measurements, the performances of these new models will be evaluated and the selected models will be ajusted to adapt to the worldwide for all sky surface net radiation calculation. Moreover, this project will try to explore some common scientific issures in quantitative remote sensing and relevent disciplines, such as quality control of measurements, error propagation, evaluative criteria of different methods, big data modeling, and scaling.
