| Abstract: | In this research, the thermal insulation covers were installed for the seismometers of Daqintala Seismic Station in Inner Mongolia Autonomous Region. And we used the PSD probability density function of seismic observation data before and after thermal insulation that was calculated by using the calculation software of base noise to analyze the effect of thermal insulation cover for seismometer. The result suggested that the seismometer temperature changed smoothly and the quality of seismic observation data was improved. |
