East End
2013-12-19

I arrived about 1:00 with Patty. It was sunny, mild and super windy. The wind speed was better than 12m/s. The sheep were gone. There might have been a little more water in the channels.

The 7700 read: 2.07% RSSI, 8ppm, after cleaning the RSSI was 66.9%
The wash reservoir was empty. We refilled the reservoir and decided that the filter was leaking on this box too. We taped it up as best we could.

The 7500 read: 16.34mmol/m3 CO2, 173mmol/m3 H2O, 100.88kPa, 17.02C, 249 diag

We dug a hole to the south of the tower in the edge of the channel for the well pressure sensor sn 20010375. We stole the pipe from the Alfalfa well to use here. The top of the pipe was 53cm above the ground and the water level was at the ground surface. We need to get the well pressure to determine the depth of the sensor.

The remaining PAR sensor was dangling from the top of the tower and banging on the data logger box in the wind when we got there. I reinstalled both PAR sensors near the end of the boom with bolts.

No changes were needed to the met program as the added sensors were already in the code. We collected all the data.

The 4-channel radiometer was very dirty from bird feet.

Patty put a couple more bolts in scaffolding to fix the upper railing to the rest.

The solar panels had some bird poop on them so they got washed.
