Urumqi One-Second Resolution Geomagnetic Data
2002-2003
==========================================
<<< An Explanation of Urumqi One Second Resolution
　　　　　　Geomagnetic Data on the CD-ROM >>>
==========================================

      The one-second resolution geomagnetic field data are useful in various 
research fields such as geomagnetic pulsation, crustal resistivity, etc..  
However, it is still not so convenient to use such high-time resolution data 
on-line because of the limitation in network transfer speed.


   This CD-ROM contains the one second resolution geomagnetic field data 
observed at Urumqi Magnetic Observatory located at (Geographic Latitude, 
Geographic Longitude) = (43.80, 87.70) as a research collaboration among 
China Earthquake Administration, Xinjiang Seismological Bureau and World 
Data Center for Geomagnetism, Kyoto. The latest data are available from the 
data center through WWW on-line service 
(http://swdcwww.kugi.kyoto-u.ac.jp/).


   Three magnetic components (H, Z and D) are measured by a fluxgate 
magnetometer every second with 0.01nT resolution. The values are derived 
using provisional base line values.


   The data on this CD-ROM are written with 2-byte binary integer usually 
used in the UNIX system on most work stations.  We need to exchange the 
order of the two (i.e.,  upper and lower) bytes when we use the data with 
PCs (i.e., DOS, LINUX, WINDOWS etc.). The sample program on this CD-ROM 
written in C and FORTRAN language can be used in most systems. This CD-ROM 
contains a Setup program for WindowsXP.  This software was developped by Dr. 
Y. Sanoo at Asahi University. To install it, double click the 'Setup' icon.


   The directory and file structure in this CD-ROM is as follow:
         readme.txt
　　     format.txt
         sample.c
         sample.f
         Setup.exe  (quick_viewer)
