最近用傅里叶变换红外光谱辐射计测量了日本阿索火山一个无法接近的火山口的火山气体。在火山柱光谱中确定了CO、COS、CO2、SO2和HCl的吸收特征。这是首次通过远程技术同时探测到五种火山气体成分。根据测得的CO/CO2比为2.6 × 10−3，火山气体的平衡温度估计为750° ± 120°C。
Volcanic gas from an inaccessible fumarole at Aso volcano, Japan, was recently measured with a Fourier Transform InfraRed (FT‐IR) spectral radiometer. Absorption features of CO, COS, CO2, SO2, and HCl were identified in the volcanic plume spectra. This is the first time the five volcanic gas components are detected simultaneously by a remote technique. Based on the measured CO/CO2 ratio of 2.6 × 10−3, the equilibrium temperature of the volcanic gas is estimated to be 750° ± 120°C.
