Equipment and Calibration History

History for Kipp & Zonen PAR-LITE 990031

Rec No.	Date	Loc From	Title	Loc To	Notes
5670	2022-02-02	East End PAR Sensor Undercanopy C	Moved	Gilbert Tract PAR Sensor Incoming	Removed from lower location south of the tower at East End. This sensor was disconnected from the data logger two weeks before. This sensor was moved to GT to replace the incoming PAR there that was having negative values at night.
5231	2021-03-30	Lab none	Installed	East End none	Installed in EE wetland to measure undercanopy PAR. This sensor is S of the tower mounted on a grounding rod. The sensor is sitting in a heterogeneous patch of dried reeds about 30cm above the water level
5114	2021-02-10	Tonzi PAR Sensor Incoming Cal	Removed	Lab none	Removed from Tonzi Tower after three weeks of inter comparison with the AMP standard
5058	2021-01-21	Lab none	Installed	Tonzi none	Installed as part of the inter-comparison kit to test PAR, AirT and RH on the top of the Tower.
4936	2020-10-26	Lab none	Repair	Lab none	The cable insulation on this sensor was rotted. I cut the cable off near the sensor and spliced on a new cable. I also added an aluminum bracket to provide strain relief and used liquid electrical tape to seal the hole where the cable enters the sensor.
4805	2020-09-29	Vaira PAR Sensor Reflected Cal	Removed	Lab none	Removed from the tower (reflected cal) for repair - the cable is all rotted
4801	2020-09-16	Vaira PAR Sensor Reflected	Moved	Vaira PAR Sensor Reflected Cal	Moved from the main reflected position to the reflected cal position in preparation to being removed.
31	2010-01-08	Vaira PAR Sensor Reflected	Location	Vaira PAR Sensor Reflected	This instrument is installed in the downward diretion collecting PAR reflected from the surface. Calibration factor on instrument is 5.08 µV/µmol/s.m2
2344	2000-10-07	Lab none	Installed	Vaira PAR Sensor Reflected	Installed facing down with the initial set up of the Vaira site.
