This is the second paper of a series devoted to atmospheric optical turbulence C2 n observation using a mobile polar atmospheric parameter measurement system. We present the initial results of C2 n me
In recent decades, significant changes of Arctic sea ice have taken place. These changes are expected to influence the surface energy balance of the ice-covered Arctic Ocean. To quantify this energy b
Sea ice in the western Antarctic Peninsula(WAP) region is both highly variable and rapidly changing. In the Palmer Station region, the ice season duration has decreased by 92 d since 1978. The sea-ice
自20世纪80年代初世界上第一台高光谱成像仪问世以来,高光谱遥感技术获得了突飞猛进的发展,应用领域不断拓宽,使之成为遥感发展的重要前沿之一,目前高光谱遥感应用领域已遍及地表资源生态调查和地下资源能源勘查等许多方面,对固体地球的探测和能源矿产勘查为主体的应用所展现出巨大的潜力一直都是高光谱遥感技术应用的重点领域。20世纪80年代中后期,我国中科院上海技术物理所研制完成了"红外细分光谱扫描仪",
本文利用中尺度可分辨云模式(WRF,Weather Research and Forecasting)对2011年8月14日北京地区一次强降水过程进行了数值模拟和敏感性试验,研究了城市环境(包括城市气溶胶和城市地表)对北京地区云和降水的影响.研究结果表明:城市气溶胶污染增强和城市地表使得北京地区(城区和周边)降水量减少,对城区平均累积降水量的影响作用分别为-38.92%和-3.4%.降水系统向北京
风蚀沙埋是风沙活动区植物生长发育面临的重要干扰因子。以塔克拉玛干沙漠南缘策勒绿洲-沙漠过渡带主要建群种疏叶骆驼刺(Alhagi sparsifolia)和花花柴(Karelinia caspica)幼苗为研究对象,通过控制试验设置对照、1/3 H(H为林高)沙埋、2/3 H沙埋、3/3 H沙埋、风蚀2cm、风蚀5cm和风蚀10cm等7个处理,测定处理后2种植物幼苗的丙二醛、可溶性糖、叶绿素含量和光
The analysis of a territorys climatic water balance dynamics against the background of climate change is a key component for increasing water resource management efficiency. The present study aims to
