Abstract :
A method of estimating the excess in optical thickness of stratospheric aerosol after a big volcanic eruption by combining use of IR 10 mm split-window data and microwave dual-frequency data taken from MOS-1 satellite is presented. The estimation method of stratospheric aerosol optical thickness is derived by simulation study, then its method is applied to satellite data. The method is feasible for the detection of aerosol and also is also applied to correct the dense stratospheric aerosol absorption effect when the sea surface temperature is derived by satellite
