I arrived about 10:45 with Cove. It was cool and overcast with little to no wind. A light spotty rain was falling when we arrive and increased to a steady light rain when we left. The road was in better condition this time, but it looks like the truck that services the outhouse got stuck sometime in the last few days.

The tram was stopped partway down the track. We reset it but its batter seemed weak. Later when is started up again it quit partway down the track again so we brought it in.

We added a power relay to the Vaisala probes at Tree one and rewired the other relays at the soil CO2 site. With the new relay and wiring, turning the Vaisala probes on and off seemed to work correctly.

I copied the data from the Floor CR1000 and uploaded a new program to use the sonic’s timing to drive the data collection. The new program is running in sequential mode and cycling at 50Hz but data is still being collected at 10Hz. When a message comes in from the sonic the program gets data from the LI7500 to match with it. A couple of the empty 50Hz cycles missed while this happens.

Cove cleaned all the sensors at the top of the tower including the phenocam that had a spot in its images.
