1A regional ionospheric TEC mapping technique over China and adjacent areas: GNSS data processing and DINEOF analysis显示文摘A technique is developed to derive two-dimensional maps of total electron content(TEC) over China and adjacent areas using Global Navigation Satellite System(GNSS) data from the Crustal Movement Observation Network of China(CMONOC) and the International Global Navigation Satellite System Service(IGS). A revised self-calibration of pseudo-range errors(SCORE) algorithm is used to derive the TEC and to determine the Differential Code Biases(DCBs) simultaneously. The accuracy and validity of this technique is verified in two ways. Firstly, the estimated TEC is compared with the results derived using DCBs from Center for Orbit Determination of Europe(CODE) under different solar activity conditions and seasons; secondly, sample TEC along the receiver-to-satellite ray paths are simulated by Ne Quick model and are reprocessed by this TEC derivation technique to make the accuracy test. Two-dimensional maps of vertical TEC of ionospheric pierce points(IPPs) are obtained accordingly with a time resolution of 30 s. The data interpolating empirical orthogonal functions(DINEOF) technique is then used to make the extrapolation for the unknown or missing data points. The optimal EOF modes for data reconstruction are specified via cross-validation method. The regional TEC distribution over China and adjacent areas is scaled into grid size of 1? × 1? for each 5 min, which can well reflect the characteristic of large-scale regional variations and temporal evolution as well as the small-scale local features of ionosphere.A Ercha HUANG WenGeng LIU SiQing SHI LiQin GONG JianCun CHEN YanHong SHEN Hua 2015Science China(Information Sciences)2015,58,10:3

3Development of Operational Space Weather Prediction Models显示文摘In this report, we summarize the needs of space weather models, and recommend that developing operational prediction models, rather than transitioning from research to operation, is a more feasible and critical way for space weather services in the near future. Operational models for solar wind speed, geomagnetic indices, magnetopause, plasma sheet energetic electrons, inner boundary of ion plasma sheet, energetic electrons in outer radiation belt, and thermospheric density at low Earth orbit, have been developed and will be introduced briefly here. Their applications made a big progress in space weather services during the past two years in China.GONG Jiancun LIU Siqing SHI Liqin LUO Bingxian CHEN Yanhong HUANG Wengeng CAO Jinbin XIE Lun LEI Jiuhou TANG Weiwei 2014空间科学学报2014,34,5:1
4Advances in Research and Service of Space Environment in China显示文摘This paper presents the recent progress of space environment research and service in China.During the past two years,many models of space environment forecast and analysis methods of space environment effects have been developed for tailored space environment service for Chinese space mission.A new Re-locatable Atmospheric Observatory(RAO) for monitoring atmospheric wind,temperature,density and pressure of the near space from 20km up to 120km altitudes is being constructed.In space environment service space environment safety was provided to ensure the safety of CE-1 for its launch and operation in 2007.SHI Liqin GONG Jiancun LIU Siqing HU Xiong LIU Jing HUANG Wengeng 2008空间科学学报2008,28,5:0
