Summary: Deployed new GHG system with LI7550 box and LI7500 head after old one was damaged in rain

Arrived at 14:00. It was sunny but hazy and there was a light breeze.

We collected met data, soil CO2 data and swapped the CF camera card.

We setup the new GHG system consisting of a brand new LI7550 box sn AIU-1557 and a LI7500 head sn 75H-2514. The system seemed to work fine after we set it up. SOS seemed a little bit low, but might be fine. There were no bird spikes on the 7500, we found some broken ones in one of our toolboxes and taped them on. But they should probably be replaced.

LI7500 readings:
sn 75H-2514 (up)
CO2 441.68 umol/mol
H2O 411.7 mmol/m3
T 15.83 Celsius
P 102.08 kPa
SS 100.12
SOS 341.804
