Remote sensing reflectance during POLARSTERN cruise ANT-XXIV/4

In the previous remote sensing reflectance (RRS) data sets , the RRS data were not correctly calculated because the input upwelling radiance (Lu) data were wrongly shifted by 3...在既往的遥感反射率（remote sensing reflectance, RRS）数据集中，由于输入的上行辐亮度（upwelling radiance, Lu）数据被错误偏移了3（原文未完整说明偏移的具体内容与单位），导致RRS数据未能得到正确计算。
