1 | BMS | | Upwelling LI-200 | 05/12/2021 | 10:20:00 | 05/12/2021 | 12:13:00 | The relay multiplexer on the SRRL BMS radiometer tower had a problem (old age/possible moisture) that caused low voltage measurements on the main CR3000 wiring panel to read bogus, this includes all 40-South measurements and all upwelling shortwave measurements (except upwelling CMP11). |
2 | BMS | | Upwelling LI-200 | 05/15/2020 | 13:20:00 | 12/15/2021 | 19:31:00 | DATA CORRECTED on 12/17/2021: Irradiances were increased by 0.675% due to revised BORCAL report for all BMS shortwave radiometers calibrated in 2020 and 2021. |
3 | BMS | | Upwelling LI-200 | 10/15/2010 | 00:00:00 | 12/06/2010 | 09:01:00 | The LI-200 is reading zero or bogus during this time. On 10/20/2010, the instrument was removed from service and the channel was shorted. The instrument was disassembled and the Silicon sensor was found to be bad. Another spare sensor was installed on 12/6/2010. Note: This also affects the Albedo (LI-200) calculation. |
4 | BMS | | Upwelling LI-200 | 10/09/2010 | 16:50:00 | 10/14/2010 | 10:23:00 | The LI-200 is reading zero or bogus during this time. On 10/14/2010, the bendix connector at the instrument was completely soldered, which seemed to fix the problem. Note: This also affects the Albedo (LI-200) calculation. |
5 | BMS | | Upwelling LI-200 | 09/10/2010 | 08:50:00 | 10/07/2010 | 15:00:00 | The LI-200 is reading zero during this time. Instrument cable (from logger to bendix connector) was replaced on 10/6/2010, which did not solve the problem. On 10/7/2010, the bendix connector at the instrument was partially re-soldered, which seemed to fix the problem. Note: This also affects the Albedo (LI-200) calculation. |
6 | BMS | | Upwelling LI-200 | 07/17/2010 | 04:00:00 | 09/09/2010 | 08:51:00 | The LI-200 is reading zero during this time. The bendix connect was between the logger and sensor was disconnected, sprayed with contact cleaner, and reconnected, which seemed to fix the problem. Note: This also affects the Albedo (LI-200) calculation. |
7 | BMS | | Upwelling LI-200 | 07/10/2010 | 11:44:00 | 07/14/2010 | 13:04:00 | The LI-200 is reading zero or bogus during this time. The bendix connect was between the logger and sensor was disconnected and reconnected, which seemed to fix the problem. Note: This also affects the Albedo (LI-200) calculation. |
8 | BMS | | Upwelling LI-200 | 07/03/2010 | 00:00:00 | 07/06/2010 | 10:03:00 | The LI-200 is reading zero or bogus during this time due to a loose screw on the multiplexer. Note: This also affects the Albedo (LI-200) calculation. |
