|---|---|---|---|---|---|
| 5915 | 2022-08-01 | Lab none | Installed | Mayberry Anemometer | Installed on MB after testing in the lab. Sonic heading = 10 deg true N. |
| 5916 | 2022-07-31 | Lab none | Tested | Lab none | Tested the sonic and its cable in the lab with Joe's help over e-mail. Both tested fine. I mated the sonic cable with an Eosense cable and used the conductivity setting on the voltmeter to find the 4 eosense wires that corresponded to outputs 1-4. At rest (while I was standing still next to the sonic), the voltages were around +/- 8mV. I then used a fan to test U, V, W. The voltages went up to around 150mV. Placing the fan on the opposite side of the sonic produced about the same magnitude voltage with the opposite sign. SOS (output 4) was around 1.7V and didn't change much with the fan, as expected. I wired the Eosense cable to a CR1000 with a NL115 and ran it overnight, storing 30min and 20Hz data on an 8gb card. The data the next morning seemed reasonable. SOS had the same pattern as PanelT. Sonic pin -> Licor color -> Eosense cable 8 (Output 1) -> white -> brown 14 (Output 2) -> green -> white 9 (Output 3) -> grey -> pink 15 (Output 4) -> blue -> black 10 (Analog G) -> red -> grey 16 (Analog G) -> pink -> yellow 17 (Analog G) -> yellow/brown -> blue |
| 5913 | 2022-07-26 | Mayberry Anemometer | Removed | Lab none | Removed from MB tower for inspection back at the lab. The sonic heading was 7 deg true N before removal. |
| 5648 | 2022-01-02 | Lab none | Installed | Mayberry Anemometer | Installed on the MB to replace sn 153804, which was removed b/c of bad SOS numbers. This sonic was installed at a heading of 23 deg true N as measured by my phone compass. |
| 5566 | 2021-11-05 | Bouldin Alfalfa-ADEX Anemometer Bouncer Lower | Removed | Lab none | Removed from bouncer tower (lower position) and brought back to the lab at the conclusion of this year's advection experiment |
| 5387 | 2021-07-20 | Lab none | Installed | Bouldin Alfalfa-ADEX Anemometer Bouncer Lower | This sonic was installed as part of the upwind tower for the advection experiment. It was installed at 242cm agl on a cross arm on the tripod tower 283m northwest of the main tower. The sonic heading is 19deg and it is about 0.5m northwest of the tripod center post. |
| 5314 | 2021-06-09 | Sherman Wetland | Removed | Lab none | Removed from SW Tower at the conclusion of the sonic intercomparison |
| 5262 | 2021-05-13 | Lab none | Installed | Sherman Wetland Anemometer Cal | Installed on Sherman Wetland tower next to the permanent sonic for a an intercomparison |
| 5245 | 2021-04-15 | Sherman Wetland Anemometer Cal | Removed | Lab none | Removed from SW and brought back to the lab at the conclusion of the intercomparison |
| 5225 | 2021-03-25 | Lab none | Installed | Sherman Wetland Anemometer Cal | Installed at SW for inter-comparison. The analog out are fed to the 7700 to record at 20Hz to check variances. |
| 5152 | 2021-03-02 | Cal Kit Anemometer | Removed | Lab none | Removed from TZ Tower top with the calibration kit |
| 5112 | 2021-02-10 | Lab none | Installed | Cal Kit Anemometer | Installed on the TZ Tower for inter-comparison. This sensor is the one that got wet when the BC tower fell over. It's mounted on the post just north of the main eddy sensors, at the same height, and oriented to true north. |
| 5106 | 2021-02-01 | Lab none | Tested | Lab none | After being removed from a partially submerged position on the fallen BC tower, I tested this sensor in the lab. There was no evidence that water had leaked inside. I connected it to a Licor system and used fans to blow air through in on the floor. The response sign and magnitude looked about right. I plan to run it on the Tonzi tower for a couple weeks to check its performance. |
| 5071 | 2021-01-29 | Bouldin Corn Anemometer | Removed | Lab none | Removed due to the tower falling over in the storm near midnight on 2021-01-26/27. Partially submerged |
| 4302 | 2019-12-13 | Lab none | Installed | Bouldin Corn Anemometer | Installed at Bouldin Corn after re-assembling tower. This unit replaces sn 074417 that lost a transducer when the tower fell. |
| 4101 | 2019-09-04 | Bouldin Alfalfa-ReleaseEx Anemometer Upper | Removed | Lab none | Removed from Bouldin Alfalfa with the end of the CH4 release experiment. This unit was at the top of the secondary tower |
| 4087 | 2019-08-16 | Lab none | Installed | Bouldin Alfalfa-ReleaseEx Anemometer Upper | Installed for CH4 release experiment. This unit was part of a secondary, lower eddy system |
| 3875 | 2019-02-06 | Loaned | Returned | Lab none | Returned by Tibisay Perez who used it at Whendee Silver's compost pile experiment in Marin |
| 3437 | 2018-05-01 | Lab none | Loaned | Loaned | Loaned to Tibisay Perez in Whendee Silver's lab for use at their Marin compost site while one of their sonics is repaired. |
| 3083 | 2017-09-26 | East End-Temp2 Anemometer | Removed | Lab none | Brought back to the lab with the decommissioning of the East End closed canopy temporary tower 2 |
| 2836 | 2017-06-14 | Lab none | Installed | East End-Temp2 Anemometer | Installed with initial setup of East End closed vegetation temporary tower for the summer of 2017 |
| 2756 | 2017-05-11 | Vaira | Removed | Lab none | Removed from Vaira because the Ameriflux intercomparison finished and because we received new 7500A and sonics from Ameriflux. This sonic was replaced with brand new sonic from Ameriflux, sn 170524. |
| 2699 | 2017-04-10 | Lab none | Installed | Vaira | Added to the Vaira eddy tower for the Ameriflux inter-comparison and the transition to newer LI-7500A eddy systems. |
