Sea Surface Salinity, Miras SMOS, Near Real-Time, Global 0.25°, 2010-present, Daily

Sea Surface Salinity - Near Real Time - Miras SMOS Daily Composite. CoastWatch/OceanWatch Level-3 SSS products are generated directly from the ESA MIRAS SMOS Level-2 swath Network Common Data Format (NetCDF) files (currently V6.62; see release "https://earth.esa.int/documents/10174/1854503/SMOS-Level-2-Ocean-Salinity-v662-release-note" ). There are two SSS variables in V6.62 L2 NetCDF files, SSS_corr (corrected for land-sea contamination) and SSS_uncorr. The CoastWatch L3 product ingests the SSS_corr with values between 25 - 40 Practical Salinity Scale (PSS). These products improve the application of satellite SSS products in NOAA by minimizing the data latency to within 24 hours of Level-2 data availability.

海洋表面盐度——近实时——Miras SMOS每日合成数据。CoastWatch/OceanWatch第三级海洋盐度（SSS）产品直接从欧洲航天局（ESA）MIRAS SMOS第二级扫描网络通用数据格式（NetCDF）文件（当前版本为V6.62；参见发布说明“https://earth.esa.int/documents/10174/1854503/SMOS-Level-2-Ocean-Salinity-v662-release-note”）生成。V6.62 L2 NetCDF文件中包含两个SSS变量，即SSS_corr（已校正陆地-海洋污染）和SSS_uncorr。CoastWatch第三级产品采用SSS_corr变量，其值介于25至40实际盐度尺度（PSS）之间。这些产品通过将数据延迟最小化至第二级数据可用后24小时内，提升了卫星海洋盐度产品在NOAA中的应用效果。
