在8 ~ 12 μm波段的基础上增加20 μm光谱观测值，可以显著提高空间和地面红外云相测定的精度。在SHEBA实验中，我们用船载FTIR光谱仪测量的北极层云7-20 μm辐射光谱证明了这一点。我们的结果与激光雷达、微波辐射计和雷达数据得到的相位分类进行了比较。
Adding 20 μm spectral observations to observations in the 8–12 μm region can significantly improve infrared cloud phase determination from both space and the surface. We demonstrate this with 7–20 μm radiance spectra of Arctic stratus clouds measured by a ship‐based FTIR spectrometer during the SHEBA experiment. Our results are compared with phase classifications obtained from lidar, microwave radiometer, and radar data.
