IMOS - SRS Surface Waves Sub-Facility - SAR wave - Near real-time data

Sentinel-1 A and B satellites are part of Europe’s Copernicus Earth Observation program and carry identical C-band Synthetic Aperture Radar (SAR) instruments. Over open-ocean, they operate in wave mode and collect directional wave measurements globally. This dataset contains Sentinel-1 SAR directional ocean swell wave number spectra, spectral partitions and partition bulks in the Australasian region including the Pacific islands, this mission has flown since 2014, with data delivered from July 2015. The data have been homogenised to a single, easily usable format from inconsistent source product by removing various discrepancies such as inconsistencies in wave number bins and values, variables and erroneous measurements over land.
The data represented by this record, are presented in real-time.

Sentinel-1A与1B卫星隶属于欧洲哥白尼地球观测计划（Copernicus Earth Observation program），二者搭载完全一致的C波段合成孔径雷达（Synthetic Aperture Radar，简称SAR）载荷。在开阔洋面工况下，该卫星编队以波模式运行，可在全球范围内采集定向海浪观测数据。本数据集涵盖澳大拉西亚区域（包含太平洋岛屿）内的Sentinel-1 SAR定向海洋涌浪波数谱、谱分区及分区体数据。该任务自2014年起投入运行，相关数据自2015年7月起对外发布。原始来源产品格式不一，通过移除波数箱与数值、变量的不一致性，以及陆地区域的错误观测等各类偏差，本数据集已被统一规整为单一易用的标准化格式。
本记录所对应的数据以实时形式提供。
