用卫星CH_4通道监测地震前兆的可能性

THE POSSIBILITY OF A KIND OF EARTHQUAKE PRECURSOR MONITORING USING SATELLITE CH_4 CHANNELS

通过辐射传输计算研究了大气CH_4浓度增加与大气顶处于CH_4吸收带通道中出射辐射的关系,指出选用适当的CH_4通道可在卫星上监测到地震前大气中CH_4浓度的增加,从而有可能作为一种地震前兆监测的手段,用于预报地震。

The relationship between the increase of CH_4 concentration in the atmosphere and the exit radiance in some channels in CH_4 absorption bands was investigated through radiative transfer calculations. It was found that with proper CH_4 channels on satellites the increase of CH_4 concentration in the atmosphere in seismic areas before earthquake can be monitored, hence it might become a useful means to monitor a kind of earthquake precursor and be used in earthquake prediction.
