| Net Radiometer | |||||
| 2007-03-27 | 020476 | CNR1 | Installed | Net Radiometer 4-way | Installed on the radiation boom |
| 2010-02-05 | 020476 | CNR1 | Calibration | Net Radiometer 4-way | cal coefficient 10.27 |
| 2011-03-01 | 020476 | CNR1 | Removed | Net Radiometer 4-way | Removed from the tower due to bad PRT readings. sn 990181 installed in place. |
| 2011-08-12 | 020476 | CNR1 | Installed | Net Radiometer 4-way | This radiometer was reinstalled on the tower after it was determined that the problem with the PRT was due either to the resistor bridge or possible a programming bug that used the wrong excitation channel. It was installed with a new resistor bridge. |
| 2013-05-09 | 020476 | CNR1 | Removed | Net Radiometer 4-way | This CNR1 was removed from the Sherman tower due to negative shortwave out readings at night. It was replace by CNR1 sn 990181 |
| 2015-05-12 | 021029 | NR-LITE | Removed | Net Radiometer | Removed with the decommissioning of the Sherman Cow Pasture site. |
| 2011-03-01 | 990181 | CNR1 | Installed | Net Radiometer 4-way | Installed on the tower to replace the original one (sn 020476) that had a bad PRT reading. |
| 2011-08-12 | 990181 | CNR1 | Removed | Net Radiometer 4-way | Removed from the Sherman tower. |
| 2013-05-09 | 990181 | CNR1 | Installed | Net Radiometer 4-way | This CNR1 was installed on the Sherman Tower to replace CNR1 sn 020476. The old CNR1 had negative shortwave readings at night. |
| 2015-05-12 | 990181 | CNR1 | Removed | Net Radiometer 4-way | Removed with the decommissioning of the Sherman Cow Pasture site. The cables are all cracked and need to be replaced |
