[1]利用大气红外探测仪（AIRS）进行的新的红外测量，推断了对流层上部和平流层下部火山二氧化硫（SO 2）的浓度。利用1362 cm−1附近的SO2强吸收特征（ν3带）推导出SO2的柱丰度。反演考虑了来自整个波段的水汽的干扰。从最近几次火山爆发的例子来说明的技术和检索进行比较，同期的SO2紫外线测量臭氧监测仪器（OMI），全球臭氧监测实验（GOME）和总臭氧测绘光谱仪（TOMS）。
[1] The concentrations of volcanic sulphur dioxide (SO2) in the upper troposphere and lower stratosphere are inferred using new infrared measurements made by the Atmospheric Infrared Sounder (AIRS). Column abundance of SO2 is derived using the strong SO2 absorption feature near 1362 cm−1 (ν3-band). The retrieval takes into account interference from water vapor across the band. Examples from several recent volcanic eruptions are given to illustrate the technique and the retrievals are compared to contemporaneous SO2 ultraviolet measurements from the Ozone Monitoring Instrument (OMI), Global Ozone Monitoring Experiment (GOME) and Total Ozone Mapping Spectrometer (TOMS).
