MRI: Development of Novel Profiling Buoy Technology for Satellite Ocean Color Calibration and Data Product Validation.

PI请求核磁共振资金，以开发和评估一种新的剖面浮标系统的性能，以校准卫星海洋颜色观测并验证其数据产品。这种测量能力对于建立长期的海洋生物圈卫星气候数据记录至关重要。作为标准海洋学研究巡航的一部分，近地表剖面浮标将在每次多日部署期间自主收集100‘S的高质量近地表辐照度/辐照度剖面。NSPB建立在为浑浊水环境设计的光学剖面仪器的最新进展的基础上，该仪器适用于海洋颜色卫星数据的校准和验证。NSPB系统的目的是进行为期一天到一周的部署，提高与卫星数据的高质量匹配的可能性，而不是使用传统的剖面图技术。广泛影响遥感业界迫切需要增加提供海洋真实辐射测量，以替代对海洋颜色传感器的校准，特别是在现有设施未覆盖的地理区域。原则上，浮标加剖面仪设备为满足这一需求提供了一种新颖而令人兴奋的技术。拟议的仪器使改进的卫星验证和校准成为可能，这可能会使广大科学家和其他用户受益。建议的解决方案结合了系泊系统和基于船只的部署的优点。浮标将被保留，以便它可以收集大量数据，但不会太长，以至于生物污染开始成为一个重大问题。此外，较小的总体规模将减少部署所需的基础设施。该提案强调了这一发展将对一家商业公司(生物圈仪器公司)产生的积极影响。

The PI requests MRI funding to develop and evaluate the performance of a novel profiling buoy system for the calibration of satellite ocean color observations and the validation of their data products. This measurement capability is essential for creating long-term satellite climate data records of the ocean biosphere The Near Surface Profiling Buoy (NSPB), will autonomously collect 100's of high-quality, near-surface irradiance / radiance profiles during each multi-day deployment as part of a standard oceanographic research cruise. The NSPB is built upon recent advances in optical profiling instrumentation designed for turbid water environments that is adapted to the calibration and validation of ocean color satellite data. The NSPB system is aimed at making day-long to week-long deployments improving the likelihood of high quality match-ups with satellite data than is possible with conventional profiling techniques.Broader ImpactsIncreased provision of sea-truth radiometry for vicarious calibration of ocean colour sensors, particularly in geographical regions not covered by existing installations, is urgently required by the remote sensing community. In principle, the buoy-plus-profiler device offers a novel and exciting technique for satisfying this need. The improved satellite validation and calibration made possible by the proposed instrumentation will likely benefit a wide group of scientists and other users. The proposed solution combines the benefits of a moored system with a boat based deployment. The buoy will be left so that it can collect large amounts of data, but not so long that bio-fouling starts to become a significant issue. In addition, the smaller overall size will reduce the infrastructure required for deployment. The proposal highlights the positive impact this development will have on a commercial company (Biospherical Instruments, Inc.).
