Abstract

The ability to simulate the surface energy balance is key to studying land–atmosphere interactions; however, it remains a weakness in Arctic polar sciences. Based on the analysis of meteorological data from 1 June to 30 September 2014 from an automatic weather station on the glacier Austre Lovénbreen, near Ny–Ålesund, Svalbard, we established a surface energy balance model to simulate surface melt. The results reveal that the net shortwave radiation accounts for 87% (39 W m–2) of the energy sources, and is controlled by cloud cover and surface albedo. The sensible heat equals 6 W m–2 and is a continuous energy source at the glacier surface. Net longwave radiation and latent heat account for 31% and 5% of heat sinks, respectively. The simulated summer mass balance equals –793 mm w.e., agreeing well with the observation by an ultrasonic ranger.

2014年消融期间，斯瓦尔巴群岛奥斯特-洛温格林的表面能平衡

模拟地表能量平衡的能力是研究陆地-大气相互作用的关键；然而，它仍然是北极极地科学的一个弱点。基于对2014年6月1日至9月30日斯瓦尔巴群岛Ny–Ålesund附近Austre Lovénbreen冰川自动气象站的气象数据的分析，我们建立了一个模拟地表融化的地表能量平衡模型。结果表明，短波净辐射占能源的87%（39 W m–2），受云量和地表反照率的控制。显热等于6 W m–2，是冰川表面的连续能源。净长波辐射和潜热分别占散热器的31%和5%。模拟的夏季质量平衡等于-793毫米水柱，与超声波测距仪的观测结果非常一致。

期刊介绍： Since 1982, Polar Research has been the international, peer-reviewed journal of the Norwegian Polar Institute, Norway''s central institution for research, environmental monitoring and mapping of the polar regions. Aiming to promote the exchange of scientific knowledge about the Arctic and Antarctic across disciplinary boundaries, Polar Research serves an international community of researchers and managers. As an open-access journal, Polar Research makes its contents freely available to the general public. Original primary research papers comprise the mainstay of Polar Research. Review articles, brief research notes, letters to the editor and book reviews are also included. Special issues are published from time to time. The scope of Polar Research encompasses research in all scientific disciplines relevant to the polar regions. These include, but are not limited to, the subfields of biology, ecology, geology, oceanography, glaciology and atmospheric science. Submissions from the social sciences and those focusing on polar management and policy issues are welcome. Contributions about Antarctica are particularly encouraged.
