4194 2019-10-01 Lab none Calibration Lab none New calibration factor of 14.5 uV/(W/m2).

Tested this sensor at Oxford Tract against AMP 4-band radiometer CNR4 sn 16084. See RT Report "Oxford Tract Radiometer Comparison - 09/2018" for details. https://nature.berkeley.edu/biometlab/bmetdata/rtreport.php?screen=view&id=27

I'm not sure why the calibration factor is 5% different from the previous calibration in the summer, and which is the "better" calibration to use. The summer had a wider range of Rnet values, but the sensors were more clean in the fall. I think the fall calibration is better.
4052 2019-08-16 Lab none Calibration Lab none New calibration factor of 13.7 uV/(W/m2).

Tested this sensor at Oxford Tract against AMP 4-band radiometer CNR4 sn 16084. See RT Report "Oxford Tract Radiometer Comparison - 06/2018" for details.
