History
| Rec No. | Date | Loc From | Title | Loc To | Notes |
|---|---|---|---|---|---|
| 6462 | 2023-11-07 | Loaned none | Returned | Lab none | Returned from Yuankun Xu (Roland Burgmann Lab) and Yifang Cheng at the conclusion of their field project at the Slumgullion Landslide site in Colorado. |
| 6379 | 2023-08-22 | Lab none | Loaned | Loaned none | Loaned to Yuankun Xu (Roland Burgmann Lab) and Yifang Cheng (Berkeley Seismo Lab) for use at Slumgullion Landslide site in Colorado for about one month mid-Sept to mid-Oct. Loaned with sonic sn 152603 and CR6s sn 2114 and sn 2115. |
| 6106 | 2022-11-30 | Bouldin Alfalfa-ADEX Anemometer Bouncer Lower | Removed | Lab none | Removed from the main tower and brought back to the lab at the end of the ADEX intercomparison |
| 5841 | 2022-04-25 | Lab none | Installed | Bouldin Alfalfa-ADEX Anemometer Bouncer Lower | Installed on a cross arm at the Bouncer tower at 2.42m alg for the advection experiment at BA |
| 5771 | 2022-04-06 | Lab none | Tested | Lab none | I tested this sensor briefly in the lab against sn 152601. U and V had a much smaller magnitude. I checked the analog settings and they had been set to 5m/s range. I changed U and V from 5m/s to 30m/s. I left W as 5m/s. U, V, W, SOS seem reasonable. I will be moving this intercomparison to my backyard tomorrow to run for a few days outdoors. |
| 5660 | 2022-01-13 | Lab none | Tested | Lab none | This sonic was giving bad SOS analog output at Mayberry after a bunch or messy power cycles. Today in the lab the digital SOS was 350m/s at 34% humidity and 102.5kPa and 25C. Sonic temp reading about 5C high - seem too much with high pressure and low humidity. I check the settings and the fourth analog output that should be SOS was set to Status (good is high, bad is low) which makes sense with the data we were seeing. I reset the fourth Analog output to SOS, saved the config. All winds were reading zero in the lab. I check the SOS output on the calibration Licor box and it read 350, same as the digital. Might need to do an inter-comparison before I trust the SOS. |
| 5647 | 2022-01-02 | Mayberry Anemometer | Removed | Lab none | Removed from the MB tower and brought back to the lab for testing. The SOS was bad. Before removing, I measured a heading of 26 deg true N on my phone compass. |

| 2600 | 2017-01-25 | Lab none | Upgrade | Lab none | Upgraded firmware to correct for W bug.
