Profiles of downward irradiance and upward radiance during L'Atalante cruise ATA03 in the Atlantic Ocean at station 009001@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.本数据集针对水体内部的向下辐照度（downward irradiance）Ed(z,λ)与向上辐亮度（upward radiance）Lu(z,λ)的垂直剖面开展了测定，所用仪器为Satlantic剖面辐射计（SPMR-SeaWiFS Profiling Multichannel Radiometer）。该仪器可覆盖412纳米至700纳米波段范围内的13个探测通道，最大测量剖面深度达90米。所有测量工作均严格遵循SeaWiFS验证工作组（Mueller与Austin，1995）发布的技术规范执行。采样数据速率为6赫兹。SPMR仪器的自由下落速度通过压载物进行校准，确保每米水深可采集超过5条光谱样本。
