Abstract
The Absolute Measurement Session during the XIVth IAGA Workshop on Geomagnetic Observatory Instruments, Data Acquisition and Processing was held at the Changchun Magnetic Observatory (CNH) September 14-17, 2010. Approximately 50 participants joined in this session. During the session, 27 DI-Flux magnetometers were used to make and compare measurements, and several total field comparison measurements were conducted to look for errors within 4 total field instruments. This session also included absolute measurement training with lectures and practical training, an introduction to INTERMAGNET, and the demonstration of Autodif MKII and DI3.
