Cloud optical thickness retrieved from horizontal fields of reflected solar spectral radiance measured with AisaEAGLE during VERDI campaign 2012

The data contain ten horizontal fields of cloud optical thickness, retrieved from airborne measured reflected solar spectral radiance at 550 nm wavelength. The data were obtained during the airbone VERtical Distribution of Ice in Arctic clouds (VERDI) campaign based at Inuvik, North West Territories, Canada between 17 April and 17 May 2012. The applied fields of reflected solar spectral radiance were measured with the imaging spectrometer AisaEAGLE (36.3° field of view, 467 spatial pixels, 400-970 nm wavelength range) mounted on the Polar 5 research aircraft of the Alfred-Wegener-Institute, Helmholtz Centre for Polar and Marine Research, Bremerhaven, Germany.

本数据集包含10组水平分布的云光学厚度（cloud optical thickness）数据，该数据由机载测量得到的550纳米波长处反射太阳光谱辐射亮度反演得到。数据集采集自以加拿大西北地区因纽维克为基地的北极云冰垂直分布（VERtical Distribution of Ice in Arctic clouds, VERDI）科考项目，采集时段为2012年4月17日至2012年5月17日。本次研究使用的反射太阳光谱辐射亮度数据，由搭载于德国不来梅哈芬亥姆霍兹极地与海洋研究中心阿尔弗雷德·魏格纳研究所“极地5号”研究飞机的成像光谱仪AisaEAGLE测得；该仪器视场角为36.3°，包含467个空间像素，波长覆盖范围为400~970纳米。
