| 1 | Low-frequency sea level variation and its correlation with climate events in the Pacific显示文摘Global mean sea level(GMSL) has not only significant secular trend and seasonal variations,but also inter-annual and decadal variations.This paper reconstructs the time series of GMSL variations between 1948 and 2007 by combining satellite altimeter measurements and tide gauge observations.Based on the time series,the acceleration of GMSL rise in the second half of 20th century is estimated to be 0.010±0.009 mm/a 2,and multi-scale low frequency sea level oscillations including decadal variations are detected,and the high-rate of GMSL rise during 1993-2003 is locate in the ascending phase of low frequency oscillation.Then,using the reconstructed GMSL time series after removing the secular trend from satellite altimetry and tide gauges measurements,it shows that low frequency signal of sea level variation has strong correlations with the index of El Ni o/Southern Oscillation(ENSO) and Pacific Decadal Oscillation(PDO).But in several time periods,they have large difference due to effects of both high frequency occurrence of El Ni o and La Ni a phenomenon and short term switch of PDO events. | JIN TaoYong LI JianCheng JIANG WeiPing CHU YongHai | 2012 | Chinese Science Bulletin2012，57，27： | 6 |
| 2 | The global mean sea surface model WHU2013显示文摘The mean sea surface(MSS) model is an important reference for the study of charting datum and sea level change. A global MSS model named WHU2013, with 20? 20 spatial resolution between 80S and 84N, is established in this paper by combining nearly 20 years of multi-satellite altimetric data that include Topex/Poseidon(T/P), Jason-1, Jason-2, ERS-2,ENVISAT and GFO Exact Repeat Mission(ERM) data, ERS-1/168, Jason-1/C geodetic mission data and Cryosat-2 low resolution mode(LRM) data. All the ERM data are adjusted by the collinear method to achieve the mean along-track sea surface height(SSH), and the combined dataset of T/P, Jason-1 and Jason-2 from 1993 to 2012 after collinear adjustment is used as the reference data. The sea level variations in the non-ERM data(geodetic mission data and LRM data) are mainly investigated, and a combined method is proposed to correct the sea level variations between 66S and 66N by along-track sea level variation time series and beyond 66S or 66N by seasonal sea level variations. In the crossover adjustment between multi-altimetric data, a stepwise method is used to solve the problem of inconsistency in the reference data between the high and low latitude regions. The proposed model is compared with the CNES-CLS2011 and DTU13 MSS models, and the standard derivation(STD) of the differences between the models is about 5 cm between80S and 84N, less than 3 cm between 66S and 66N, and less than 4 cm in the China Sea and its adjacent sea. Furthermore, the three models exhibit a good agreement in the SSH differences and the along-track gradient of SSH following comparisons with satellite altimetry data. | Taoyong Jin Jiancheng Li Weiping Jiang | 2016 | Geodesy and Geodynamics2016，7，3： | 4 |
| 3 | Variability of the Kuroshio extension system in 1992-2013 from satellite altimetry data显示文摘The Kuroshio Extension(KE) plays an important role in climate and environmental change in the North Pacific. In this paper, more than 20 years of merged absolute dynamic topography and merged sea level anomaly products from satellite altimetry are used to analyze the stability of the KE system. By analyzing the annually averaged sea surface topography, the variations of inter-annual path and annually averaged eddy kinetic energy at the KE region, the KE's two dynamic states are given as: the relatively stable state during 1993e1995, 2002e2005, and 2010e2012, and the unstable dynamic state among 1996e2001 and2006e2009. During the stable state, the KE spindle had a shorter path length and smaller time-varying amplitude, as well as a trend to move northward. While during the unstable state, the KE spindle had a longer path length and an integral southward transport trend, and was observed to oscillate significantly over time. The analysis on the KE's upstream and downstream region gives the same variations, indicating that they are significantly affected by the El Nino events. The power spectrum of the mean latitudinal position variation of the KE's upstream and downstream shows significant quasi-decadal oscillation characteristics and strong annual signals. Furthermore, the correlation of the strength variation between the southern RG and the KE's upstream is calculated to be 0.50 after low-pass filtering,and that of the mean latitudinal position variation between the southern RG and the KE's upstream/downstream are 0.75/0.69 after low-pass filtering, respectively. The strong correlations demonstrated that the southern RG and the KE are closely linked. | Weiping Jiang Lifeng Peng Taoyong Jin Shengjun Zhang | 2017 | Geodesy and Geodynamics2017，8，2： | 1 |

| 5 | A new Arctic MSS model derived from combined Cryosat-2 and ICESat observations显示文摘Due to the existence of seasonal or perennial sea ice cover,the determination of the Arctic sea surface is more difficult than that of mid-low latitudinal oceans.Focusing on the sea surface height in the ice-covered region,this paper constructs a new Arctic mean sea surface(MSS)model,named SUST22,by combining the measurements from ICESat and Cryosat-2 missions.The lead detection methods of ICESat and Cryosat-2 are first studied and modified to acquire sea surface measurements with better accuracy.The results have shown that the standard deviation of Cryosat-2-derived Arctic sea surface height is about 3–4 cm in 10-km resolution grids,while the value of ICESat is 5–6 cm.Then the MSS construction procedure is discussed and the SUST22 MSS model is constructed.The new model is compared with the other four Arctic MSS models.The best agreement is found between SUST22 and DTU21 with an average difference of−4.0±5.2 cm.These models are also validated by ICESat-2 samples.The average difference between ICESat-2 and SUST22 is 15.8±7.4 cm,which shows that the new model SUST22 presents better consistency with the ICESat-2 than any of the other models. | Guodong Chen Zhijie Zhang Stine Kildegaard Rose Ole Baltazar Andersen Shengjun Zhang Taoyong Jin | 2022 | International Journal of Digital Earth2022，15，1： | 0 |
| 6 | Suitable region of dynamic optimal interpolation for efficiently altimetry sea surface height mapping显示文摘The dynamic optimal interpolation(DOI)method is a technique based on quasi-geostrophic dynamics for merging multi-satellite altimeter along-track observations to generate gridded absolute dynamic topography(ADT).Compared with the linear optimal interpolation(LOI)method,the DOI method can improve the accuracy of gridded ADT locally but with low computational efficiency.Consequently,considering both computational efficiency and accuracy,the DOI method is more suitable to be used only for regional applications.In this study,we propose to evaluate the suitable region for applying the DOI method based on the correlation between the absolute value of the Jacobian operator of the geostrophic stream function and the improvement achieved by the DOI method.After verifying the LOI and DOI methods,the suitable region was investigated in three typical areas:the Gulf Stream(25°N-50°N,55°W-80°W),the Japanese Kuroshio(25°N-45°N,135°E-155°E),and the South China Sea(5°N-25°N,100°E-125°E).We propose to use the DOI method only in regions outside the equatorial region and where the absolute value of the Jacobian operator of the geostrophic stream function is higher than1×10^(-11). | Jiasheng Shi Taoyong Jin | 2024 | Geodesy and Geodynamics2024，15，2： | 0 |
| 7 | Reply to: Parker A. Comment on “Low-frequency sea level variation and its correlation with climate events in the Pacific”显示文摘First, we would like to thank Parker for his discussion and comments on our work. Parker’s main concern [1] is that the sea level is oscillating with important multi-decadal periodicities but absolutely not positively accelerating. He also argued that the global mean sea level (GMSL) acceleration computed by Jin et al. [2] seemed too large.
