Simulated top-of-atmosphere (15 km) downward and upward solar and thermal-infrared irradiances and ice cloud optical thickness; calculated solar, TIR and net cloud radiative effect. Simulated with ice crystal properties for aggregates, droxtals, and plates based on Yang (2000).

This dataset consists of three .nc files for ice crystal shapes of aggregates, plates, and droxtals. The files include ice cloud optical thickness \(\tau\), the simulated upward and downward irradiances \(F\) at the top-of-atmosphere (with and without the presence of the ice cloud), and the calculated ice cloud radiative effect \(\Delta F\) (solar [0.3-3.5 \(\mu\)m], thermal-infrared [3.5-75 \(\mu\)m], and net). The data set allows the user to extract \(\Delta F\) values for their parameter combinations. The available cloudy and cloud-free irradiances further allow to calculate the cirrus radiative effect (RE) by scaling the 'cloudy' RE with the required cloud cover. This serves as a first-approximation because, as 3D effects are neglected.本数据集包含三个.nc格式文件，涵盖聚合冰晶、板状冰晶以及droxtals三种冰晶形态。文件中包含冰云光学厚度( au)、大气层顶处模拟得到的向上与向下辐照度(F)（分别对应存在冰云与无冰云两种场景），以及计算得到的冰云辐射效应(Delta F)，覆盖太阳波段[0.3~3.5 μm]、热红外波段[3.5~75 μm]与净辐射波段。本数据集支持用户针对其指定的参数组合提取(Delta F)数值。现有有云与无云场景下的辐照度数据，还可通过将‘有云场景’的辐射效应按所需云量进行缩放，来计算卷云辐射效应（radiative effect，RE）。该方法属于一阶近似，因未考虑三维效应。
