Aquarius Official Release Level 3 Ancillary Reynolds Sea Surface Temperature Standard Mapped Image Ascending Seasonal Data V5.0

Aquarius Level 3 ancillary sea surface temperature (SST) standard mapped image data are the ancillary SST data used in the Aquarius calibration for salinity retrieval. They are simply the daily SSTs from the Reynolds National Climatic Data Center (NCDC) 0.25 degree dataset, gridded and averaged using the Aquarius processing L2-L3 processing scheme to the same 1 degree spatial resolution and daily, 7 day, monthly, seasonal, and annual time intervals as Aquarius L3 standard salinity and wind speed products. This particular data set is the Seasonal, ascending ancillary sea surface temperature product associated with version 5.0 of the Aquarius data set, which is the official end of mission public data release from the AQUARIUS/SAC-D mission.

宝瓶座（Aquarius）三级辅助海表温度（sea surface temperature, SST）标准制图影像数据，是用于宝瓶座盐度反演定标工作的辅助海表温度数据。此类数据直接取自雷诺国家气候数据中心（Reynolds National Climatic Data Center, NCDC）0.25°分辨率数据集的每日海表温度，并通过宝瓶座L2-L3级处理流程完成网格化与平均运算，使其空间分辨率与宝瓶座三级标准盐度、风速产品保持一致的1°分辨率，同时生成与上述产品匹配的每日、7日、月度、季节及年度时间尺度的数据集。本数据集为宝瓶座数据集5.0版配套的季节升轨辅助海表温度产品，而该5.0版是宝瓶座/SAC-D（Aquarius/SAC-D）任务的官方任务末期公开数据发布成果。
