内蒙古自治区鄂尔多斯市在过去十几a中经历了经济的飞速发展与城市的快速扩张,目前却面临着经济发展的停滞与城市转型。对鄂尔多斯市城市扩张及其驱动因子在时间及空间尺度上的分析,可为鄂尔多斯市的城镇化发展规划提供参考信息。利用DMSP/OLS夜间灯光(nighttime light,NTL)遥感数据,并结合Landsat影像数据,对鄂尔多斯市2000—2013年间城市扩张进行遥感制图和信息提取; 应用基于...
磁暴期间高纬顶部电离层离子上行特征——DMSP卫星观测
离子上行 电子增温 高纬电离层 磁暴
2014/12/20
本文利用DMSP F13和F15卫星观测数据,对2001—2005年58个磁暴(-472 nT≤Min.Dst≤-71 nT)期间高纬顶部电离层离子整体上行特征进行了统计研究.观测表明,磁暴期间,顶部电离层离子上行主要发生在极尖区和夜间极光椭圆区.在北半球,磁正午前,高速的离子上行(≥500 m·s-1)多集中在65° MLat以上;午后,高速离子上行区向低纬度扩展,上行速度要略高于午前;在南半球...
