Integrated Multi-Mission Ocean Altimeter Data for Climate Research complete time series Version 5.0

This dataset contains along track Sea Surface Height Anomalies (SSHA) from the TOPEX/Poseidon, Jason-1, OSTM/Jason-2, and Jason-3 missions geo-referenced to a mean reference orbit. Altimeter data from the multi-mission Geophysical Data Records (GDRs) have been interpolated to a common reference orbit with biases and cross-calibrations applied so that the derived SSHA are consistent between satellites to form a single homogeneous climate data record. Version 5.0 updates include improved Precise Orbit Determination (POD) with GSFC std2006 standards, and the application of internal tides. The data are in netCDF format and start in September 1992. Data extensions are appended to the file quarterly. More information on data processing standards can be found in the v5.0 User Handbook (Integrated Multi-Mission Ocean Altimeter Data for Climate Research TOPEX/Poseidon, Jason-1, 2, & 3 Users Handbook: https://archive.podaac.earthdata.nasa.gov/podaac-ops-cumulus-docs/merged_alt/open/L2/TP_J1_OSTM/docs/v092120version50multialthandbook.pdf).

本数据集汇集了来自TOPEX/Poseidon、Jason-1、OSTM/Jason-2及Jason-3任务沿轨海面高度异常（SSHA）数据，这些数据基于平均参考轨道进行地理参照。来自多任务地球物理数据记录（GDRs）的测高仪数据已插值至共同参考轨道，并应用了偏差校正和交叉校准，以确保在不同卫星之间推导出的SSHA保持一致性，从而形成单一均质气候数据记录。版本5.0的更新包括采用GSFC std2006标准的改进精确轨道确定（POD）以及内部潮汐的应用。数据以netCDF格式存储，始于1992年9月。数据扩展每季度追加至文件中。关于数据处理标准的更多信息，可参考v5.0用户手册（综合多任务海洋测高仪数据气候研究TOPEX/Poseidon、Jason-1、2、& 3用户手册：https://archive.podaac.earthdata.nasa.gov/podaac-ops-cumulus-docs/merged_alt/open/L2/TP_J1_OSTM/docs/v092120version50multialthandbook.pdf）。
