摘　　要：北极地区冰/雪-大气相互作用的过程,尤其是冰雪表面反照率的变化,是制约我们认识北极地区气候系统快速变化的关键科学问题。目前已有的研究表明,随着观测技术和方法的进步,北极冰雪表面能量平衡研究取得了较大的进展,但由于缺乏高质量、时空连续的观测试验数据,大部分参数化方案、遥感及模式产品等在北极不同区域的适用性仍待评估。因此,北极地区观测站点的加密、综合观测试验的开展和多源卫星遥感体系的进一步完善,能为遥感卫星产品及复杂参数化方案在北极的评估验证提供数据支撑,也可以揭示更多潜在的冰雪表面能量平衡相关的过程和机理,加深对极地海-冰/雪-气相互作用的理解,更好地服务于极地冰冻圈与气候变化研究。Land-atmosphere interaction processes,especially glacier/snow surface albedo variations,are key scientific issues that restrict the understanding of rapidly changes(e.g.,surface temperature rising,sea ice and snow extent decreasing)in the Arctic.This study,on the basis of recent improvements of observation techniques and analysis methods,shows the marked progress achieved in characterizing the Arctic glacier/snow surface energy balance.However,due to lack of the observation data with high quality,the robustness of the parameterization schemes and dataset with remote sensing/numerical models should be further evaluated.Therefore,longer time series of comprehensive observations,at more numerous and densely distributed observation sites,are needed for future surface energy balance studies.In addition,multi-source satellite remote sensing monitoring systems should be developed to acquire large scale,three-dimensional,dynamic,and continuous datasets,for evaluation and validation of remote sensing products and complex parameterization schemes.Such data will also allow for better characterization of the mechanisms influencing the Arctic glacier/snow surface energy balance and of sea ice/snow/atmosphere interactions,thus representing an important contribution to polar cryosphere and climate change research.
