NASA SARAL Project

These data are near-real-time (NRT) (within 7-9 hours of measurement) sea surface height anomalies (SSHA) from the AltiKa altimeter onboard the Satellite with ARgos and ALtiKa (SARAL). SARAL is a French(CNES)/Indian(SARAL) collaborative mission to measure sea surface height using the Ka-band AltiKa altimeter and was launched February 25, 2013. The major difference between these data and the Operational Geophysical Data Record (OGDR) data produced by the project is that the orbit from SARAL has been adjusted using SSHA differences with those from the OSTM/Jason-2 GPS-OGDR-SSHA product at inter-...本数据集为搭载于ARGOS与ALTIKa卫星（SARAL）的ALTIKa高度计所获取的近实时（NRT，测量完成后7至9小时内）海面高度异常（SSHA）数据。SARAL是由法国国家空间研究中心（CNES）与印度联合实施的合作任务，旨在通过Ka波段ALTIKa高度计测量海面高度，该卫星于2013年2月25日发射升空。本数据集与该项目生成的业务地球物理数据记录（OGDR）的主要差异在于：研究团队利用海洋表面地形任务/杰森-2（OSTM/Jason-2）的GPS-OGDR-SSHA产品的海面高度异常差值，对SARAL的轨道进行了修正，相关修正基于跨……（原文未完整收尾）
