SRAL Level 1B Stack Echoes (version BC005) - Sentinel-3 - Reprocessed

SRAL Level 1B: Complex echoes (In-phase (I) and Quadrature (Q)) for the Low Resolution Mode (LRM) and/or Synthetic Aperture Radar (SAR) mode both for C Band and Ku band. When the altimeter is in SAR mode, this product also contains the so-called Pseudo LRM (PLRM) echoes. Complex (In-phase and Quadrature) echoes (I's and Q;s) after slant/Doppler range correction. This product is most relevant to geophysical retrieval algorithm developers (over ocean, land and ice surfaces), surface characterisations studies (e.g. impact of sea state bias, wave directional effects etc) and Quality Control systems. Sentinel-3 is part of a series of Sentinel satellites, under the umbrella of the EU Copernicus programme. This dataset contains reprocessed data from Baseline Collection 005, and is continued by the operational NTC data stream from 10/Mar/2023 onwards.

SRAL 1B级产品：涵盖C波段与Ku波段的低分辨率模式（Low Resolution Mode, LRM）及合成孔径雷达（Synthetic Aperture Radar, SAR）模式下的复回波（同相（I）与正交（Q）分量）。当高度计处于SAR模式时，本产品还包含所谓的伪低分辨率模式（Pseudo LRM, PLRM）回波。上述复回波均经过斜距/多普勒距离校正。本产品适用于地球物理反演算法开发者（面向海洋、陆地与冰面场景）、地表特征研究（例如海态偏差、波浪方向效应等的影响）以及质量控制系统，具备重要应用价值。Sentinel-3是欧盟哥白尼计划（Copernicus Programme）旗下Sentinel卫星系列的组成部分。本数据集包含基线集合005（Baseline Collection 005）的再处理数据，并自2023年3月10日起由运行中的NTC数据流持续更新。
