| 2 | Improving the accuracy of GRACE Earth's gravitational field using the combination of different inclinations显示文摘In this paper, the GRACE Earth’s gravitational eld complete up to degree and order 120 is recovered based on the combination of di erent inclinations using the energy conservation principle. The results show that because di erent inclinations of satellite are sensitive to the geopotential coe cients with di erent degrees l and orders m, the design of GRACE exploiting 89° inclination can e ectively improve the accuracy of geopotential zonal harmonic coe cients. However, it is less sensitive to the geopotential tesseral harmonic coef- cients. Accordingly, the second group of GRACE exploiting lower inclination is required to determine high-accurately the geopotential tesseral harmonic coe cients and cover the shortage of the single group of GRACE exploiting 89o inclination. Two groups of GRACE individually exploiting 89° + (82°–84°) inclinations are the optimal combination of the Earth’s gravitational eld recovery complete up to degree and order 120. In the degree 120, the joint accuracy of cumulative geoid height based on two groups of GRACE individually exploiting 89° and 83° inclinations is averagely two times higher than the accuracy of a group of GRACE exploiting 89° inclination. | Wei Zheng Chenggang Shao Jun Luo Houze Xu | 2008 | Progress in Natural Science:Materials International2008，18，5： | 34 |
| 3 | Sea level variations in the South China Sea inferred from satellite gravity,altimetry,and oceanographic data显示文摘Sea level variations(SLVs) can be divided into two major components:the steric SLV and the mass-induced SLV.These two components of SLV in the South China Sea(SCS) are studied by using satellite altimetry,GRACE(Gravity Recovery and Climate Experiment) satellite gravity,and oceanographic data on annual and inter-annual timescales.On the annual timescale,the geographic distribution of mass-induced SLV's amplitude jointly estimated from altimetry and the ECCO(Estimation of the Circulation and Climate of the Ocean) model agrees very well with that from GRACE.GRACE observes obvious seasonal mass-induced SLV in the SCS with annual amplitude of 2.7±0.4 cm,which is consistent with the annual amplitude of 2.7±0.3 cm estimated from the steric-corrected altimetry.On the inter-annual timescales,the mean SLV in the SCS shows a large oscillation,which is mainly caused by the steric effect.The trend of mean SLV inferred from altimetry in the SCS is 5.5±0.7 mm/yr for the period of 1993-2009,which is significantly higher than the global sea level rise rate of 3.3±0.4 mm/yr in the same period.There is no obvious trend signal in the mass-induced SLV detected from GRACE that indicates the water exchange between the SCS and its adjacent seas and land is in balance within the study period. | FENG Wei 1,2,ZHONG Min 1,3 & XU HouZe 1,3 1 State Key Laboratory of Geodesy and Earth’s Dynamics,Institute of Geodesy and Geophysics,Chinese Academy of Sciences,Wuhan 430077,China 2 Graduate University of Chinese Academy of Sciences,Beijing 100049,China 3 Institute of Geophysics,Huazhong University of Science and Technology,Wuhan 430074,China | 2012 | Science China Earth Sciences2012，55，10： | 15 |
| 4 | Progress in satellite gravity recovery from implemented CHAMP,GRACE and GOCE and future GRACE Follow-On missions显示文摘Firstly,the Earth's gravitational field from the past Challenging Minisatellite Payload(CHAMP) mission is determined using the energy conservation principle,the combined error model of the cumulative geoid height influenced by three instrument errors from the current Gravity Recovery and Climate Experiment(GRACE) and future GRACE Follow-On missions is established based on the semi-analytical method,and the Earth's gravitational field from the executed Gravity Field and Steady-State Ocean Circulation Explorer(GOCE) mission is recovered by the space-time-wise approach.Secondly,the cumulative geoid height errors are 1.727 × 10^(-1) m,1.839 × 10 ^(-1) m and 9.025 × 10^(-2) m at degrees 70,120 and 250 from the implemented three-stage satellite gravity missions consisting of CHAMP,GRACE and GOCE,which preferably accord with those from the existing earth gravity field models involving EIGEN-CHAMP03 S,EIGEN-GRACE02 S and GO_CONS_GCF_2_DIR_R1.The cumulative geoid height error is 6.847 × 10^(-2) m at degree 250 from the future GRACE Follow-On mission.Finally,the complementarity among the four-stage satellite gravity missions including CHAMP,GRACE,GOCE and GRACE Follow-On is demonstrated contrastively. | Zheng Wei Xu Houze | 2015 | Geodesy and Geodynamics2015，6，4： | 8 |

| 7 | Check of free oscillation signal with SG data显示文摘The observation of the Earth’s free oscillation is an important way to study the Earth’s inner structure and geophysical parameters. Many geophysicists have investigated the Earth’s normal modes with strainmeters and spring gravimeters. Since the superconducting gravimeters appeared, people have gained a new kind of more stable instruments to detect the normal modes. The measurement for the Earth’s free oscillation with the superconducting gravimeters is one of the main goals of the Global Geodynamics Project. In this note, we have investigated the Earth’s normal modes excited by Peru Ms 7.9 Earthquake on June 23, 2001 with the superconducting gravimeter C032 at the Wuhan station. After having completed the subtraction of gravity tides with the 20th order polynomial fitting, and the correction for pressure and the analysis of the noise spectrum of the superconducting gravimeter, we accurately observed all base normal modes from 0S0 to 0S32 and the splittings of 0S2 and 0S3. Those results show a good | Xiang’e Lei Houze Xu Heping Sun | 2002 | Chinese Science Bulletin2002，47，18： | 4 |
| 8 | Detection of spheriodal free oscillation excited by Peru 8.2 M_(s) earthquake with five international superconducting gravimeter data显示文摘In this paper, authors obtain the spectral peaks of the earth free oscillation and check all normal modes from 0S0 to 0S48 accurately, with the Fourier analysis and the maximum entropy spectrum method dealing jointly with six groups of the observational residual data from five international superconducting gravimeter stations. By comparing the observational results in this paper with three former groups of observations or models, authors notice an extra discrepancy between two observational 0S2 modes excited separately by Peru earthquake and Alaska earthquake, which probably mirrors the anisotropy of the Earth's inner core. The analysis on the splitting 1S2 mode shows that the asymmetric factor of rotationwise spectral splitting is possible to be different from that of anti-rotationwise spectral splitting. | LEI Xiang'e XU Houze SUN Heping | 2005 | Science China Earth Sciences2005，48，1： | 4 |
| 9 | Monthly gravity field solution from GRACE range measurements using modified short arc approach显示文摘In this paper we present a series of monthly gravity field solutions from Gravity Recovery and Climate Experiment(GRACE) range measurements using modified short arc approach,in which the ambiguity of range measurements is eliminated via differentiating two adjacent range measurements.The data used for developing our monthly gravity field model are same as Tongji-GRACEOl model except that the range measurements are used to replace the range rate measurements,and our model is truncated to degree and order 60,spanning Jan.2004 to Dec.2010 also same as Tongji-GRACE01 model.Based on the comparison results of the C_(2,0),C_(2,1),S_(2,1),and C_(15,15),S_(15,15),time series and the global mass change signals as well as the mass change time series in Amazon area of our model with those of Tongji-GRACE01 model,we can conclude that our monthly gravity field model is comparable with Tongji-GRACE01 monthly model. | Shen Yunzhong Chen Qiujie Xu Houze | 2015 | Geodesy and Geodynamics2015，6，4： | 4 |
| 10 | Earth Gravity Field Recovered from CHAMP Science Orbit and Accelerometer Data显示文摘The earth gravity field model CDS01S of degree and order 36 has been recovered from the post processed Science Orbits and on-board accelerometer data of GFZ’s CHAMP satellite. The model resolves the geoid with an accuracy of better than 4 cm at a resolution of 700 km half-wavelength. By using the degree difference variances of geopotential coefficients to compare the model CDS01S with EIGEN3P, EIGEN1S and EGM96, the result indicates that the coefficients of CDS01S are most close to those of EIGEN3P. The result of the comparison between the accuracies of geopotential coefficients in the above models, indicates that the accuracy of coefficients in CDS01S is higher than that in EGM96.The geoid undulations of CDS01S and GGM01C up to 30 degrees are calculated and the standard deviation is 4.7 cm between them. | ZHOU Xuhua WU Bin PENG Bibo XU Houze | 2006 | Geo-Spatial Information Science2006，9，4： | 2 |

| 13 | Monthly gravity field recovery from GRACE orbits and K-band measurements using variational equations approach显示文摘The Gravity Recovery and Climate Experiment(GRACE) mission can significantly improve our knowledge of the temporal variability of the Earth's gravity field.We obtained monthly gravity field solutions based on variational equations approach from GPS-derived positions of GRACE satellites and K-band range-rate measurements.The impact of different fixed data weighting ratios in temporal gravity field recovery while combining the two types of data was investigated for the purpose of deriving the best combined solution.The monthly gravity field solution obtained through above procedures was named as the Institute of Geodesy and Geophysics(IGG) temporal gravity field models.IGG temporal gravity field models were compared with GRACE Release05(RL05) products in following aspects:(i) the trend of the mass anomaly in China and its nearby regions within 2005-2010;(ii) the root mean squares of the global mass anomaly during 2005-2010;(iii) time-series changes in the mean water storage in the region of the Amazon Basin and the Sahara Desert between 2005 and 2010.The results showed that IGG solutions were almost consistent with GRACE RL05 products in above aspects(i)-(iii).Changes in the annual amplitude of mean water storage in the Amazon Basin were 14.7 ± 1.2 cm for IGG,17.1 ± 1.3 cm for the Centre for Space Research(CSR),16.4 ± 0.9 cm for the GeoForschungsZentrum(GFZ) and 16.9 ± 1.2 cm for the Jet Propulsion Laboratory(JPL) in terms of equivalent water height(EWH),respectively.The root mean squares of the mean mass anomaly in Sahara were 1.2 cm,0.9 cm,0.9 cm and 1.2 cm for temporal gravity field models of IGG,CSR,GFZ and JPL,respectively.Comparison suggested that IGG temporal gravity field solutions were at the same accuracy level with the latest temporal gravity field solutions published by CSR,GFZ and JPL. | Wang Changqing Xu Houze Zhong Min Feng Wei | 2015 | Geodesy and Geodynamics2015，6，4： | 1 |

| 17 | 2004年12月26日苏门答腊——安达曼地震激发的地球自由振荡显示文摘根据300-500s的面波估计得到的哈佛大学矩心矩张量断层机制,当周期大于1000s时,地球的地震自由振荡的振幅将异常地大。我们对一个比较陡的断层应用根据地震的体波和面波得到的更真实的破裂模型,估计了自由振荡的振幅近似等于地震矩(6.5×10^22 N·m),这相当于矩震级为9.15。由于破裂的持续时间达600s,故断层破裂模型足以描述地震的观测结果,但却低估了大地测量位移,这些位移表明在尼科巴群岛和安达曼群岛下面发生了缓慢的断层运动。 | J.
