Summary: Bird poop on Tower 7500 window, Tress beginning to leaf out

When: Mar 12 2004
Where: Tonzi/Vaira Ranch
Who: Liukang Xu
Weather: Sunny, temperature upper 70s, about 30% of oak trees near Irish Rd already leaf out, but not for trees near our flux tower.

Tower EC system was running great. Fence OK. PV reading 13.8, 0, 4.6. Gillsonic output for q and CO2 were 3.101 and 0.355 V, caused by bird poop on the lens of li7500. Cleaned the lens and reboot pc gave me right values for all the channels.

On Mar 4th, Ted replaced the pc, systems seems running better, but I do see the watchdog problem once.

Floor EC, system was running great. Download data, PV reading 13.9, 14.1, 2.5.Gillsonic outputs are all in the right range.

All Jianwu’s 8 probes are working.
