Summary: Finish installing folding radiation boom, gillsonic.exe hung up - restarted

When: Thur-Fri, 29-30 Apr04, JD120-121
Where: Tonzi Ranch
Who: Ted Hehn
Weather Clear & warm

13:30 Friday julian day 121 remove signal leads from differential channel 5 which is the net radiometer to lengthen signal leads to reconfigure to new boom arm.

16:10 Net rad signal leads restored. Sn 990351 13.9 uv/w m2

Install Kipp & Zonen PAR up sensor on tower and place leads into the PAR calibration channel. The PAR down sensor is connected to nothing. After a side by side calibration on the Licor PAR sensors is performed the Licor sensors will be removed and the K&Z PARs will replace them.

K&Z up sn 010159 5.16 umol/m2/s
K&Z dn sn 030382 5.29 umol/m2/s

Pyranometer sn 996981 5.03 uv/w/m2

Licor PAR up sn Q29892 6.66 uA/1000umol s-1 m-2
Licor PAR dn sn Q29881 6.65 uA/1000umol s-1 m-2

16:33 level all radiation sensors: Net Rad, pyran, 2 Licor Pars, 2 K&Z Pars

20:44 Tower PC not taking data sonic working gillsonic locked in infinite loop. Stop gill sonic and let PC208 start â€“ ok begins taking data.

20:47 all now working

Remove net radiometer from met station near tower base - unit to the east of the tower sn 990352 14.2 uv/w/m2.

Net rad to north of tower left operating
