Profiles of downward irradiance and upward radiance during L'Atalante cruise ATA03 in the Atlantic Ocean at station 015001@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.采用Satlantic剖面辐射计（Satlantic profiler，SPMR-SeaWiFS Profiling Multichannel Radiometer）测定了水体中下行辐照度（downward irradiance）Ed(z,λ)与上行辐亮度（upward radiance）Lu(z,λ)的垂直剖面分布。本次测量覆盖412 nm至700 nm波段的13个通道，剖面深度可达90 m。所有测量均遵循SeaWiFS验证团队（Mueller与Austin，1995）提出的规范要求，采样数据速率为6 Hz。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到超过5条光谱样本。
