Top of Atmosphere, Hyperspectral Synthetic Dataset for PACE (Phytoplankton, Aerosol, and ocean Ecosystem) Ocean Color Algorithm Development

This synthetic dataset was created to provide a measurement error-free hyperspectral (350-800 nm, 5 nm resolution) dataset as part of research performed by the first NASA PACE (Plankton, Aerosols, Cloud, and Ocean Ecosystem) Science Team (NNH13ZDA001N-PACEST). A synthetic dataset of sea surface and top of atmosphere (TOA) radiances were constructed by a Coupled Ocean Atmosphere Radiative Transfer (COART) model (Du and Lee, 2014) based on the SBDART (Santa Barbara DISORT Atmospheric Radiative Transfer) code (Ricchiazzi et al. 1998), with ocean contribution simulated by Hydrolight (Mobley, 2008). Water-leaving radiance (Lw) was forward modelled with Hydrolight with a solar zenith angle of 30°, cloudless sky, a sea surface state corresponding to a wind speed of 5 m/s, and realistic concentrations of optically active water constituents.

本合成数据集旨在提供一套免于测量误差的、具有（350-800 nm，5 nm分辨率）的高光谱数据集，作为NASA PACE（浮游生物、气溶胶、云层和海洋生态系统）科学团队（NNH13ZDA001N-PACEST）所进行的研究项目的一部分。该数据集通过耦合海洋大气辐射传输（COART）模型（Du 和 Lee，2014年）构建，该模型基于SBDART（Santa Barbara DISORT大气辐射传输）代码（Ricchiazzi 等，1998年），并通过Hydrolight（Mobley，2008年）模拟海洋贡献。利用Hydrolight模型，在太阳天顶角为30°、晴空无云的条件下，对对应于5 m/s风速的海面状态进行了水反照率（Lw）的前向建模，并模拟了具有现实光学活性水组分浓度的真实情况。
