History
| Rec No. | Date | Loc From | Title | Loc To | Notes |
|---|---|---|---|---|---|
| 5222 | 2021-03-25 | Lab none | Installed | Hill Slough Net Radiometer 4-way | Installed at Hill Slough at the end of the radiation boom. The NR-LITE was moved back along the boom. |
| 5206 | 2021-03-16 | Sherman Wetland Net Radiometer 4-way Cal A | Removed | Lab none | Removed from SW at the conclusion of the 4-way intercomparison test and brought back to the lab |
| 5139 | 2021-02-26 | Lab none | Installed | Sherman Wetland Net Radiometer 4-way Cal A | Installed on the Sherman Wetland tower for inter-comparison after repair in the lab. It is clamped near the end of the square tube of the radiation boom pointing south. |
| 5118 | 2021-02-18 | Lab none | Repair | Lab none | Over the last week or so I disassembled and cleaned this sensor. I don't see any water damage but I can't get the LW junction board loose as it seems glued to the case. I totally replaced the four wires running between the LW and SW sides. These wires were broken after having been previously broken and spliced. I soldered new wires directly to the junction boards. I collected about two days of data on the window sill with the sensor partially disassembled so that all four sensors could point up together. The relationship between the paired sensors was very tight (r-squared >0.99) - excluding a portion of the LW data that might have been affected by solar heating. LW had a sloped of 1.01 but SW had a slope of 1.20 - new calibration coefficients are probably needed. Today I completely reassembled the sensor and put it out the window on a boom to collect some data to check the assembly. |
| 5107 | 2021-01-30 | Lab none | Damaged | Lab none | This sensor was removed from a submerged position on the fallen BC tower. The shortwave side had been torn loose breaking the wires similar to last time it was damaged. After returning to the lab on the 29th I pulled it apart and tried to air it out. On the 30th it was still damp inside and I ran dry air through the holes under the circuit boards for two days. |
| 5073 | 2021-01-29 | Bouldin Corn Net Radiometer 4-way | Removed | Lab none | Removed due to the tower falling over in the storm near midnight on 2021-01-26/27. Completely submerged and broken in two pieces |
| 2718 | 2017-04-26 | Lab none | Installed | Bouldin Corn Net Radiometer 4-way | Installed at the Bouldin Corn site with the initial set up of the tower. |
| 2522 | 2016-11-02 | Vaira | Removed | Lab none | Removed from Vaira with the radiometer inter-comparison system that was on a stand alone tripod. |
| 2509 | 2016-10-20 | Twitchell Rice | Moved | Vaira | Moved with radiometer test tripod from Twitchell Rice to Vaira Ranch to compare against Ione sensors. |
| 2472 | 2016-09-22 | Lab none | Installed | Twitchell Rice | Installed on an independent tripod at Twitchell Rice. This is part of a "golden" radiometers experiment to compare incoming PAR and SW across the delta |
