Ocean Surface Topography Mission (OSTM) /Jason-3: Near Real-Time Altimetry Validation System (NRTAVS) QA Reports, 2015 - (NODC Accession 0122600)

Jason-3 is the fourth mission in U.S.-European series of satellite missions that measure the height of the ocean surface. Scheduled to launch in 2015, the mission will extend the time series of ocean surface topography measurements begun by the TOPEX/Poseidon satellite mission in 1992 and continuing through the currently operating Jason-1 (launched in 2001) and OSTM/Jason-2 (launched in 2008) missions. These measurements provide scientists with critical information about circulation patterns in the ocean and about both global and regional changes in sea level and the climate implications of a warming world.

TOPEX/Poseidon and Jason-1 were cooperative missions between NASA and the French space agency, CNES. Additional partners in the Jason-2 mission included NOAA and Eumetsat. Jason-3 continues the international cooperation, with NOAA and Eumetsat leading the efforts, along with partners NASA and CNES.

The primary instrument on Jason-3 is a radar altimeter. The altimeter measures sea-level variations over the global ocean with very high accuracy (as 1.3 inches or 3.3 centimeters, with a goal of achieving 1 inch or 2.5 centimeters).

These files provide the quality reports from the Near Real-Time Altimetry Validation System.

杰森-3（Jason-3）是美欧联合海洋表面高度测量卫星任务系列的第四项任务。该任务原定于2015年发射，旨在延续自1992年TOPEX/Poseidon卫星任务启动、并由当前在轨运行的杰森-1（2001年发射）与OSTM/Jason-2（2008年发射）任务持续开展的海洋表面地形测量时间序列。此类测量可为科学家提供关键信息，涵盖海洋环流模式、全球及区域海平面变化，以及全球变暖背景下海平面变化的气候影响。

TOPEX/Poseidon与杰森-1是美国国家航空航天局（NASA）与法国国家空间研究中心（CNES）的合作任务。杰森-2任务的额外合作方包括美国国家海洋和大气管理局（NOAA）与欧洲气象卫星组织（Eumetsat）。杰森-3延续了这一国际合作模式，由NOAA与Eumetsat牵头，合作伙伴包括NASA与CNES。

杰森-3的核心载荷为雷达高度计。该高度计可高精度测量全球海洋的海平面变化，测量精度可达1.3英寸（约3.3厘米），目标精度为1英寸（约2.5厘米）。

本数据集包含近实时测高验证系统（Near Real-Time Altimetry Validation System）生成的质量报告。
