Summary: Standard data collection, re-positioned camera because it was pointing down toward the ground

We arrived at 9:45. It was cool, mostly sunny with some light clouds. There were many sandhill cranes nearby.

We downloaded met data and USB GHG data and swapped camera CF card. The camera CF card only had data until 12/25. Likely an issue with aging CF card.

We cleaned the radiation, CO2, and CH4 sensors. The wash reservoir was __ full. We refilled it?

The camera was pointing down towards the field (maybe a bird sat on it?). We connected to the camera directly through the black "Ethernet 10Mbps" cable and used the program "Stardot Tools" to see a live feed of the camera. We re-positioned the camera so that it had about 1/3 sky and 2/3 ground in its view.

We are missing a bird spike on top of the 7500. It might be helpful to add a bird spike to the camera box.

The 7500 read:
CO2 413ppm
H2O 305 mmol/m
T 9.8C
P 101.8kPa
SS 78.1 --> 78.4 after cleaning

The 7700 read:
CH4 1.98ppm
RSSI 57.0 --> 78.0 after cleaning
