Summary

1. The aspiring bump for Vaira Ta&Rh didn’t work. I clicked it, and it worked again, but not very strong.
2. checked and downloaded data at Tower, Floor, and Vaira
3. swapped Li-7500 at Tower and Floor site.
4. returned the TRAM to the field.
5. returned the Soil CO2 probes to the field.
6. Didn’t calibrate Li-800 in the field because the CO2 profile system was off for power saving purpose.
7. collected grass samples for LAI
8. dendrometers
9. soil moisture
10. groundwater well:

1. downloading data YES!
2. swap IRGA: remove #73; install #1594.
3. Check MD-9 system connections YES!

CR23X5 – soil CO₂ profile
Put CO2 probes back after Jacyln did comparison in the lab.
Reset power, but indicator showed “battery low”. LOOKS OK!


CR23X6 – tower-Met

CR10X2 – floor-Met

CR23X3

1. Soil CO₂ profile: no power when I got there. I unplug and re-plug fuses, then the system back to work.

Reading from datalogger
Reading from panels of analyzers
Read after installation, might not be balanced.
