摘要

开发并测试了一种新型海洋剖面浮标系统,用于校准和验证卫星海洋颜色观测结果。浮筒辐射采样系统(以下简称 HyperNav)是对传统系泊式现场观测系统的补充,由于平台体积相对较小,辐射精度高,可在最适合海洋颜色观测的季节和条件下择机部署,因此具有更强的能力。本研究的目的是通过执行系统虚拟校准(SVC)观测,优化 HyperNav 系统阵列的部署位置,以支持浮游生物、气溶胶、云层和海洋生态系统(PACE)任务。具体来说,我们介绍了如何制定后勤和科学标准,以选择合适的地点来开发能够校准和验证海洋颜色观测数据的基于辐射测量系统的剖面浮标 SVC 网络。作为本文所述分析的一部分,我们在潜在的美国和国际站点综合部署了 HyperNav,这些站点包括:克里特岛北部、百慕大群岛东南部、波多黎各岛南部、加利福尼亚州胡内姆港西南部、加利福尼亚州蒙特雷西部、夏威夷州科纳西部和塔希提岛西南部。合成分析确定科纳、波多黎各、克里特岛和塔希提岛为有希望的 SVC 地点。所有考虑的地点都适合生成大量验证匹配。在 PACE 发射后 SVC 活动期间,在这些站点优化部署 HyperNav 系统,预计将以具有成本效益的方式提供大量 SVC 匹配,以满足 PACE 校准要求。

Selecting HyperNav deployment sites for calibrating and validating PACE ocean color observations
A novel ocean profiling float system for calibrating and validating satellite-based ocean color observations has been developed and tested. The float-based radiometric sampling system, herein referred to as HyperNav, is complementary to traditional moored in-situ observing systems and provides additional capability due to the relatively small platform size and high radiometric accuracy that allows for opportunistic deployments at locations during seasons and conditions that are best for ocean color observations. The purpose of this study is to optimize the deployment locations of an array of HyperNav systems to support the Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission by performing System Vicarious Calibration (SVC) observations. Specifically, we present the development of logistical and scientific criteria for selecting suitable sites for developing an SVC network of profiling-float-based radiometric systems capable of calibrating and validating ocean color observations. As part of the analyses described in this paper, we have synthetically deployed HyperNav at potential US-based and international sites, including: north of Crete island; south-east of Bermuda island; south of Puerto Rico island; southwest of Port Hueneme, CA; west of Monterey, CA; west of Kona, HI; and south-west of Tahiti island. The synthetic analyses identified Kona, Puerto Rico, Crete, and Tahiti as promising SVC sites. All sites considered are suitable for generating a significant number of validation match-ups. Optimally deploying HyperNav systems at these sites during the PACE post-launch SVC campaign is expected to cost-effectively provide a large number of SVC match-ups to fulfill the PACE calibration requirements.
