Calibration |
Factory none |
y=mx+b 149.48 0; The date for this entry is made up but allows this calibration to be used as needed. After discrepancies with an inter-comparison on Tonzi Tower in the spring to 2021 and a conversation with Sebastien Biraud on 2021-05-05 we learned that the OSU calibration for this senor was no good and the subsequent calibration that this entry represents should be used instead. The OSU calibration uses a lamp and fails for certain PAR sensors for unknown reasons. This calibration is done at LBL outside under ambient conditions cross compared with ten other PAR sensors. |
