Oceansat-2 50 km winds Release 2 - Reprocessed

Reprocessed stress-equivalent 10m winds over the global oceans obtained from the Oceansat-2/OSCAT scatterometer on a 50 km swath grid. The complete data record from the Ku-band scatterometer OSCAT on Oceansat-2 (15 December 2009 - 20 February 2014) has been reprocessed using the Pencil Beam Wind Processor (PenWP). ERA5 re-analysis winds from the European Centre for Medium-Range Weather Forecasts (ECMWF) have been used to initialise the ambiguity removal step in the wind processing and for validation and monitoring of the wind retrievals. ISRO has provided the near-real time Oceansat-2 level 1b data which were used as input for the OSI SAF wind products. NASA's Jet Propulsion Laboratory has kindly provided their archived OSCAT data record to the OSI SAF.本数据集为经再处理的全球海洋应力等效10米风场，数据源自搭载于海洋卫星2号（Oceansat-2）的OSCAT散射计（OSCAT scatterometer），采用50公里幅宽的网格进行格点化处理。2009年12月15日至2014年2月20日期间，Oceansat-2搭载的Ku波段（Ku-band）散射计OSCAT的完整观测记录，已通过笔形波束风处理器（Pencil Beam Wind Processor, PenWP）完成再处理。欧洲中期天气预报中心（ECMWF）提供的ERA5再分析风场（ERA5 re-analysis winds）被用于初始化风处理流程中的模糊度去除步骤，同时也用于风反演结果的验证与监测。印度空间研究组织（ISRO）提供了近实时Oceansat-2 1b级数据（level 1b data），该数据被用作OSI SAF风产品的输入数据源。美国国家航空航天局（NASA）喷气推进实验室慷慨共享了其归档的OSCAT数据记录，供OSI SAF使用。
