OHP Superconducting Gravimeter Data Superconducting gravimeter data taken at OHP stations (see the following map ) can be downloaded from this site. The data files contain superconducting gravimeter data and atmospheric pressure data. These data are compiled into daily files for each station and stored as ascii (text) files. Please see the readme.txt for the details of the data format. Whole period data (about 2Gb) are available upon request. Please write to tamura@miz.nao.ac.jp for request of the data and for questions regarding the superconducting gravimeter data. Superconducting Gravimeter Data readme.txt
