Shigaraki Microbarometric Database (2006.08 - Latest)

Abstract on this data set

A barometric sensor (Vaisala PTB210) was installed in August 2006 at the Shigaraki MU radar site (34.8N, 136.1E), which belongs to the RISH (Research Institute of Sustainable Humanosphere), Kyoto University, by the DACGSM (Data Analysis Center for Geomagnetism and Space Magnetism), Graduate School of Science, Kyoto University. The sensitivity is about 1 Pa although the A/D resolution is 0.25 Pa. The time resolution is one second and each value is an average of 490 samples/second, and the absolute accuracy of the clock is also one second with a GPS time server.

Data format

Data are written with ASCII characters as a text file. One file contains the data for one UT day. The first 3 lines are the header of the file. Each record indicates the time (Year, Month, Day, Hour. Minutes, Second) and the observed and high-pass filtered data in hPa unit. In FORTRAN, each data record is written in the format; I4,4I3,F6.2,2F10.3

Following is a sample list of the first 15 lines (i.e., for 12 seconds) of the data file on September 10, 2006, “sga20060910.fil”.
