1/9/2006 | Mike McNaughton | At 9 PM UTC, Jan 9, 2006, the multiplier for the LAHS PIC was changed from 1.00 to 1.05. | Station Info | Data Graph |
6/25/2003 | Allen Treadaway | The gamma PIC was calibrated at about 19:45--20:00 hrs Z using the Cs-137 source # 812-44-1. The spike is a result of that calibration. | Station Info | Data Graph |
12/2/2002 | Mike McNaughton | The increased gamma rate at about 17:00 Z December 1 was caused by a mixture of rain and snow. A similar increase was observed at S site. | Station Info | Data Graph |
10/30/2002 | Allen Treadaway | While testing the 300 Vdc battery for the HPIC (High Pressurized Ion Chamber) for comparison to other NEWNET stations, a small increase in the gamma value appeared on the display outside. This test was done while the NEWNET station was still powered on to prevent any loss of other data. | Station Info | Data Graph |
10/22/2002 | D Young | At 15:10Z Kevin Anderson put a calibration source on the gamma detector to perform a calibration test. Source will be removed at 15:35Z. | Station Info | Data Graph |
8/8/2002 | Mike McNaughton | The increased gamma rate from about 1900-2100 Z August 7 was caused by rain. | Station Info | Data Graph |
7/22/2002 | Mike McNaughton | The gamma peak at about 1300 Z July 22 was caused by rain. | Station Info | Data Graph |
7/1/2002 | Allen Treadaway | The dip in the gamma readings around 1730Z on June 28, 2002 was a result of the power at the station being turned off temporarily for a few moments to reset the datalogger. | Station Info | Data Graph |
3/20/2002 | Kevin Anderson | The increase in barometric pressure is due to a correction of the calculation in the Cam[bell Datalogger program | Station Info | Data Graph |
2/25/2002 | Kevin Anderson | At approximately 1700 Zulu, Allen Treadaway and Kevin Anderson will perform a calibration check of the gamma detector.
The detector was checked with the calibration source, and the readings were ~2% of the expected readings, well within the 5% acceptability range. | Station Info | Data Graph |
