Profiles of downward irradiance and upward radiance during L'Atalante cruise ATA03 in the Atlantic Ocean at station 007001@en

Vertical profiles of downward irradiance Ed (z,lambda) in and upward radiance Lu (z,lambda) in were determined with Satlantic profiler (SPMR-SeaWiFS Profiling Multichannel Radiometer). Profiles up to 90 m were covered in 13 channels between 412 nm and 700 nm. All measurements were made according to the recommendations of the SeaWiFS validation team (Mueller and Austin 1995). The sampling data rate was 6 Hz. The free fall velocity of the SPMR instrument was justified by ballast in such a way that more than 5 spectra were samples per meter.本数据集测定了水体内部向下辐照度Ed(z,λ)与向上辐亮度Lu(z,λ)的垂直剖面，测量采用Satlantic剖面辐射计（SPMR-SeaWiFS多通道剖面辐射计）完成。测量覆盖412 nm至700 nm波段范围内的13个通道，最大剖面深度可达90 m。所有测量均严格遵循SeaWiFS验证工作组（Mueller与Austin，1995）提出的技术规范。采样速率为6 Hz，SPMR仪器通过加装压载物调整自由下落速度，确保每米水深可采集超过5条光谱样本。
