摘要
2022年4月,内布拉斯加大学林肯市校区建立了两个新的绝对重力基站。这些数值是用一台相对重力仪从238英里范围内的四个现有监测站传送过来的,后来由美国国家海洋和大气管理局(National Oceanic and Atmospheric Administration)进行了验证。在标志高度以上22.5 cm处,林肯钟塔站和林肯博物馆站的最终值分别为980177.781±0.010 mGal和980178.079±0.010 mGal,重力梯度为-3.105 μGal/cm。本文介绍了重力值转换的过程,并提出了对今后类似工程的建议。
Two New Absolute Gravity Base Stations Established in Lincoln, NE
Two new absolute gravity base stations were established on the University of Nebraska-Lincoln City Campus in April 2022. The values were transferred with a relative gravity meter from four existing stations within 238 miles and were later validated by the National Oceanic and Atmospheric Administration. The final values at 22.5 cm above marker height are 980177.781 ± 0.010 mGal at the Lincoln Bell Tower Station and 980178.079 ± 0.010 mGal at the Lincoln Museum station with a gravity gradient of -3.105 μGal/cm. This paper describes the process of transferring gravity values and outlines recommendations for similar projects in the future.
