Summary: Radiometer inter-comparison notes

April 20

Below are the various instrument coefficients for the Vaira radiation calibration sequence:

Be advised that about one week into the procedure I requested that Liukang correct the
calibration number for the PRT in the 4 way radiometer. When exactly he did that should be found in his site note from around Feb 26, Julian day 57.--- 4 way rad data previous to his visit must be disregarded or corrected.

Calibration sensors:
Pyranometer: 4.90 uV/W m-2, sn 996985, Univ sn= 991007043
Net Rad: 14.1 uV/W m2, sn 021029
Par up: 5.28 umol/m2 s, sn 010164
Par Dn: 5.52 umol/m2 s, sn 010162
4 way net rad: 10.27 uV/watt/m2, sn 020476
4 way PRT: 1.0057

Vaira sensors
Pyranometer: 5.19 uV/W m-2, sn sn996980
Net Rad: 12.3uV/W m2, sn 990353
Par up: 5.03 umol/m2 s, sn 990025
Par Dn: 5.08 umol/m2 s, sn 990031
4 war net rad: 10.19 uV/watt/m2, sn 990181
4 way PRT: 1.0050
