Sherman
2012-12-06

I arrived about 13:10. The clouds are breaking but it is still cool with a light breeze. The field is wet and muddy. The cows are being fed near our tower. In the un-trampled areas the grass is thick and green but cropped close to the ground. The Coast Guard was flying a helicopter back and forth across the river near the bridge.

There was a billion ants camped between the box and box door. It doesn’t look like they got in the box though.

The LGR read:
12:12, 23.58C, 149.78Torr, 13.842usec, 10Hz, 1.942ppm

The 7500 read 17.0 mmol/m3 CO2, 570 mmol/m3 H2O, 247 diag.

I was worried about the 24VDC supply for the Vaisala probes, but the batteries seemed to be maintaining 24V and the system was running, so I did not change things.

The data logger clocks were okay.

The HMP45 fan needs replacing.
