| Abstract: | The observations of Tengchong continuous gravimeter of CMONOC from July 1, 2012 to June 30, 2013 are analyzed. In addition, its precision and noise levels are obtained. The results show that the noise level of Tengchong station from 1s to 100 s is about 9×10-8ms-2, and from 100 s to 100 m in is about 0.3×10-8ms-2, while the white noise level is 0.509×10-8ms-2. The precision of main tidal factors (such as O1 and M2) extends to the superconducting gravimeter SG-052 used at observing stations of the Gravity Network Center of China. M2 has the highest precision reaching 0.00 018. Tengchong continuous gravity observation can provide high precision and reliable continuous gravity data for studies about strong earthquake monitor, volcano movement monitor and gravity change before earthquakes in the Sichuan-Yunnan region. |
