4802 2020-09-16 Vaira PAR Sensor Incoming Cal Moved Vaira PAR Sensor Incoming Moved from the incoming cal position to the main incoming position.
4710 2020-08-26 Lab none Installed Vaira PAR Sensor Incoming Cal Installed at Vaira in the incoming position for inter-comparison. This sensor will likely replace the old sensor.
4713 2020-08-05 Bouldin Corn PAR Sensor Under-A Removed Lab none Removed from under the canopy at Bouldin Corn. The corn has reached maximum growth continued measurements of questionable use.
4509 2020-05-29 Lab none Installed Bouldin Corn PAR Sensor Under-A I stalled about 10cm above the ground near the picams to measure under canopy PAR
4024 2019-07-25 Mayberry PAR Sensor Reflected Water Removed Lab none Removed from MB (PAR reflected water) and brought back to the lab for testing (spiky). It was replaced by sn 010161.
3766 2018-10-25 Lab none Installed Mayberry PAR Sensor Reflected Water Installed at MB (measuring reflected water) to replace sn 010161, which was brought back to the lab for repair/calibration.
4536 2018-09-28 Lab none Calibration Lab none Calibrated in the lab by sticking it out the south-facing window in Hilgard 205 with the reference sensor sn 161073. The factory calibration was 5.58 µV/(µmol/m2·s) and the new calibration was 5.74 µV/(µmol/m2·s).

2916 2017-07-03 East End-Temp1 PAR Sensor Reflected Location East End-Temp1 PAR Sensor Reflected Checked serial number.
4313 2017-06-14 East End-Temp1 PAR Sensor Incoming Moved East End-Temp1 PAR Sensor Reflected After having been initially installed in the upward looking, incoming position on the berm, this sensor was moved to a area near open water and mounted in the downward looking, reflected position.
2893 2017-06-01 Lab none Installed East End-Temp1 PAR Sensor Incoming Installed at the East End Temporary Tower #1 Open Water location with the initial set up of this site. It is facing up measuring incoming PAR
