Summary: swapped 7500 at Vaira, HMP45 fan at Vaira dead, Tower eddy hung up, couldn't talk to soilco2 cr23x, measured water potential including grass

When: Date and Time

When: Date: 4/21/2015 , Day: 111 , Watch Time: 9:30 am .

Where: Tonzi/Vaira Ranch

Who: Siyan

Weather: cloudy

Phenology: a beautiful spring day; grasses still green; lots of yellow and purple flowers

Summary

Swapped memory cards of CR1000s at three sites. The card at Tower is labelled â€œVRâ€; the one at Vaira is â€œTTâ€.
Swapped Li-7500 at Vaira: sn 0041 on; sn 0976 off;
Tower CR1000 screen froze, but the Winflux showed the sonic good. [Winflux data looks winflux was frozen too]
Checked and downloaded phenocam images and met data from PC at Tower, Floor, and Vaira.
The fan of Vaira Ta&Rh stopped working!!!

calibrated the CO2 profile system
Couldnâ€™t talk to the datalogger of the soil CO2 probes at Tonzi from the PC.
Read dendrometers; Measured soil moisture; Measured grass height
Measure groundwater well
Measure water potential of oak leaves, pine needles, annual grass stems, and broadleaf forb stem; around -10 bar in the midday.
Took spectrum measurements at Vaira
