Data Format

All the station use identical instrumentation. Small differences between gain of the amplifier exists. Data samples taken with 40Hz sampling, are stored with GPS timing and final raw data is stored into MATLAB format version 4 (.MAT). All three components are stored to different hourly files. Hourly file includes 144000 data points. Data storing system writes also GPS status to the log file. Data storing system uses 16-bit AD-converters. The voltage values from -10V to 10V is converted to bit counts (-32768 -> +32768).
