Rec No.DateLoc FromTitleLoc ToNotes
1803 2015-04-29 Lab none Installed Tonzi-Tower Installed on the Tonzi Tower to replace NR01 sn 1720 that has spike problems.
1787 2013-06-28 Lab none Calibration Lab none Using the data from the recent deployment at the Alfalfa site new calibrations factors were determined. (document available)
SWin = 10.0uV/(W/m2)
SWout = 9.6 uV/(W/m2)
LWin = 11.15 uV/(W/m2)
LWout = 8.6 uV/(W/m2)
1028 2013-06-27 Twitchell Alfalfa Removed Lab none Pulled the CNR1 off the Twitchell Alfalfa tower. Was being tested alongside the NR01 at the site. Now in the lab.
1024 2013-06-18 Lab none Installed Twitchell Alfalfa Installed on the radiation post at the Twitchell Alfalfa for a cross comparison with the Hukseflux NR01 sn 1570
1023 2013-06-13 Twitchell Alfalfa Removed Lab none Removed from the radiation post at the Twitchell Alfalfa field due to bad readings on all channels. Later determined that the SWin channel was accidentally put into the second COM channel on the multiplexor.
1022 2013-06-05 Lab none Installed Twitchell Alfalfa Installed on the radiation post at the Twitchell Alfalfa for a cross comparison with the Hukseflux NR01 sn 1570
1019 2013-05-09 Sherman Island Net Radiometer 4-way Removed Lab none This CNR1 was removed from the Sherman tower due to negative shortwave out readings at night. It was replace by CNR1 sn 990181
388 2011-08-12 Lab none Installed Sherman Island Net Radiometer 4-way This radiometer was reinstalled on the tower after it was determined that the problem with the PRT was due either to the resistor bridge or possible a programming bug that used the wrong excitation channel. It was installed with a new resistor bridge.
390 2011-03-01 Sherman Island Net Radiometer 4-way Removed Lab none Removed from the tower due to bad PRT readings. sn 990181 installed in place.
44 2010-02-05 Sherman Island Net Radiometer 4-way Calibration Sherman Island Net Radiometer 4-way cal coefficient 10.27
1749 2007-03-27 Lab none Installed Sherman Island Net Radiometer 4-way Installed on the radiation boom
