5MH BSL Data

Data Strage

Five Mile Hill back scatter data will be straged under;
- hr1lidar.hires1.utah.edu:/home/lidar/hr1bsl_data/
- hrlx02.cosmic.utah.edu:/
- icrsrv.icrr.u-tokyo.ac.jp:/ta/work/ta/data/fmhldr/
(At present, created data on 'hr1lidar.hires1.utah.edu' are transported manually.)
Data Format

The receiver data are recorded in Text file. The file name is;
"yYYYYmMMdDDpXX.hr1bsl.hr1bsl.dat".
Now we are preparing fransform program from this text data file to DST format file.
Basically, Digital Oscillo ADC is 9 bits(0-511), and we are recording 500 sample points for each laser shot and each channel. Horizontal range and Vertical range of Oscilloscope are recorded by [us/div] unit and [mV/div] unit. (One waveform data have 10 Divisions, as ordinary.) The event time stamp is recorded using 'hr1lidar.hires1.utah.edu' CPU clock which is corrected through NTP. There are 3 types of waveform data.
- BGL - Artificial trigger event for Back Ground Light & Noise measurement.
- LED - Calibration event by flashing UV LED.
- LSR - Laser Beam Event triggered by Q-switching pulse.
The laser beam direction data are transfered from 'hr1sls.hires1.utah.edu' to 'hr1lidar.hires1.utah.edu' and both systems will record it into output file. If the laser beam direction is within 5 degrees of Receiver Mirror Axis, then receiver system will record waveform data into output file, too.

Pre-analysis Data

Five Mile Hill back scatter data will be checked every hour by cron. If there is an update data, pre-analysis data will be made by averaging all of same condition shots, and straged under;
hr1lidar.hires1.utah.edu:/home/lidar/hr1bsl_pre/
The file name is;
"yYYYYmMMdDDpXXhHHmMM.hr1bsl.[#elevation_angle].[#shot].dat".
Here is a sample (y2001m02d26p02h11m31.hr1bsl.10.25.dat).
