| 1 | 奥斯特/GPS掩星与地面雷达联合观测电离层电子密度的初步结果显示文摘1999年2月丹麦发射了一颗奥斯特小卫星,它装载了两台GPS接收机,其中一台用于电离层和中性大气掩星测量,另一台用于自主定位。本文给出了1999年10月奥斯特/GPS掩星与日本MU雷达和数字测高仪的联合观测结果。奥斯特掩星反演得到的电子密度剖面与地面雷达观测的进行了比较,结果表明:天基和地基雷达观测的电子密度是一致的。文章还给出利用GPS的单频信号反演电离层电子密度剖面技术和3维射线追踪技术模拟掩星结果。 | 张训械 P.Hoeg G.B.Larsen Stig Syndergaard Martin B.S Jakob G.R S.Fukao Kiyoshi lgarashi Seiji Kawamura | 2000 | 全球定位系统2000，25，3： | 18 |

| 3 | Exploring Greenhouse Gases Water and Climate Changes:Scientific Opportunities for the Climate and Atmospheric Composition Exploring Satellites Mission显示文摘The Essential Climate Variables(ECVs),such as the atmospheric thermodynamic state variables and greenhouse gases,play an important role in the atmosphere physical processes and global climate change.Given the need of improvements in existing ground-based and satellite observations to successfully deliver atmosphere and climate benchmark data and reduce data ambiguity,the Climate and Atmospheric Composition Exploring Satellites mission(CACES)was proposed and selected as a candidate mission of the Strategic Priority Research Program of Chinese Academy Science(SPRPCAS).This paper presents an overview of the key scientific questions and responses of EC Vs in relation to global change;the principles,algorithms,and payloads of microwave occultation using centimeter and millimeter wave signals between low Earth orbit satellites(LEO-LEO microwave occultation,LMO)as well as of the LEO-LEO infrared-laser occultation(LIO);the CACES mission with its scientific objectives,mission concept,spacecraft and instrumentation. | LIU Congliang KIRCHENGAST Gottfried SUN Yueqiang WANG Xin LU Daren BAI Weihua DU Qifei LOSCHER Armin SYNDERGAARD Stig TIAN Longfei ZHANG Zhihua | 2020 | 空间科学学报2020，40，2： | 1 |
