Rec No.DateLoc FromTitleLoc ToNotes
5099 2021-02-03 Lab none Installed Bouldin Corn Net Radiometer 4-way Installed on the BC tower to replace the Hukseflux NR01 that broke when the tower fell and still needs repair and cross comparison.
4962 2020-11-12 Sherman Wetland-Temp1 Net Radiometer 4-way Removed Lab none Removed with decommissioning of Sherman Wetland Temp tower. Brought back to the lab for cleanup.
4347 2020-01-30 East Pond Net Radiometer 4-way Moved Sherman Wetland-Temp1 Net Radiometer 4-way Removed with the decommissioning of the EP tower and installed at the new SW Temporary site 1250m upwind of the Permanent Tower.
3407 2018-04-17 Lab none Installed East Pond Net Radiometer 4-way Installed at EP tower as part of initial site set up.
3357 2017-05-25 Bouldin Corn Net Radiometer 4-way Removed Lab none Removed from BC tower because comparison is complete
2761 2017-05-10 Lab none Installed Bouldin Corn Net Radiometer 4-way Installed at Bouldin Corn to calibrate against NR01 sn 2420. Joe had replaced the sensor cables recently.
1832 2015-05-12 Sherman Island Net Radiometer 4-way Removed Lab none Removed with the decommissioning of the Sherman Cow Pasture site. The cables are all cracked and need to be replaced
1018 2013-05-09 Lab none Installed Sherman Island Net Radiometer 4-way This CNR1 was installed on the Sherman Tower to replace CNR1 sn 020476. The old CNR1 had negative shortwave readings at night.
404 2011-09-27 Lab none Tested Lab none Data was recorded on two consecutive days with similar radition (September 27 and 28, 2011) from the window on the south side of the lab. At 11:20am on day 271 the CNR was rotated 180 degrees so that the upward and downward sensors switched places. All channels seem to have similar responses. I conclude this sensor is in working order.
387 2011-08-12 Sherman Island Net Radiometer 4-way Removed Lab none Removed from the Sherman tower.
389 2011-03-01 Lab none Installed Sherman Island Net Radiometer 4-way Installed on the tower to replace the original one (sn 020476) that had a bad PRT reading.
5712 2008-06-20 Factory none Calibration Factory none Calibrated at AccuFlux.
CG_Up (LWin) = 9.66 uV/(W/m2) y=mx+b 103.52 0
CM_Up (SWin) = 9.94 uV/(W/m2) y=mx+b 100.60 0
CG_Dn (LWout)= 9.58 uV/(W/m2) y=mx+b 104.38 0
CM_Dn (SWout)= 9.96 uV/(W/m2) y=mx+b 100.40 0
3689 2001-05-20 Lab none Installed Vaira Net Radiometer 4-way Installed on the Vaira tower
5711 1999-08-20 Factory none Calibration Factory none Initial factory calibration. All four sensors were tuned to 10.19 uV/(W/m2) y=mx+b 98.14 0
