摘要

Abstract >We present freeboard measurements from airborne laser scanner (ALS), the Airborne Synthetic Aperture and Interferometric Radar Altimeter System (ASIRAS), and CryoSat‐2 SIRAL radar altimeter; ice thickness measurements from both helicopter‐borne and ground‐based electromagnetic‐sounding; and point measurements of ice properties. This case study was carried out in April 2015 during the N‐ICE2015 expedition in the area of the Arctic Ocean north of Svalbard. The region is represented by deep snow up to 1.12 m and a widespread presence of negative freeboards. The main scattering surfaces from both CryoSat‐2 and ASIRAS are shown to be closer to the snow freeboard obtained by ALS than to the ice freeboard measured in situ. This case study documents the complexity of freeboard retrievals from radar altimetry. We show that even under cold (below ?15°C) conditions the radar freeboard can be close to the snow freeboard on a regional scale of tens of kilometers. We derived a modal sea‐ice thickness for the study region from CryoSat‐2 of 3.9 m compared to measured total thickness 1.7 m, resulting in an overestimation of sea‐ice thickness on the order of a factor 2. Our results also highlight the importance of year‐to‐year regional scale information about the depth and density of the snowpack, as this influences the sea‐ice freeboard, the radar penetration, and is a key component of the hydrostatic balance equations used to convert radar freeboard to sea‐ice thickness. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract Type =“main”> <标题类型=“main”>抽象</ title> >我们提出了空机激光扫描仪（ALS），机载合成孔径和干涉雷达高度计系统（Asiras）的收银测量，以及低温-2 Siral雷达高度计;直升机和地面电磁探测的冰厚度测量;并点测量冰属性。本案例研究于2015年4月在斯瓦尔巴特北部地区的N-ICE2015探险期间进行了2015年4月。该地区由深雪达到1.12米，并且存在阴性收纸板的广泛存在。来自低温-2和ASIRAS的主要散射表面被显示为靠近由ALS获得的雪橇滑板而不是原位测量的冰冷速。本案例研究记录了从雷达Altimetry的干舷检索的复杂性。我们表明即使在寒冷（下面？15°C）条件下也可以将雷达收银机靠近雪地间隙，以几十公里的区域等级。我们从3.9米的CryoSat-2衍生出型研究区的模态海冰厚度，以测量总厚度为1.7米，导致大约海冰厚度大约在一个因素2.我们的结果也突出了重要性关于积雪的深度和密度的年度区域规模信息，因为这影响了海冰流动板，雷达渗透，并且是用于将雷达流动滚筒转换为海冰的静液压平衡方程的关键组成部分厚度。</ p> </ abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-34643/'>《Journal of Geophysical Research, C.
