Summary: replaced tower computer, diffuse PAR sensor, soil co2 data logger power supply.

Vaira
2012-04-23

I arrived about 8:30PDT. It was cool and mostly cloudy with a low overcast and light breeze from the west. The ground looks much drier with the first puddle in the road on the way in much lower and the second puddle empty of water.

I installed a replacement computer for the tower and set it up to collect the flux, met and camera streams. All seems well.

I reinstalled the diffuse PAR sensor with repaired cable. The data on the data logger looked okay. The problem of shifted channels has not occurred again. It’s getting its power from the AM16/32 power connector now. I think I need to put a power strip in the box.

I replaced the power supply for the soil CO2 CR10X. The three transmitters with LCDs read:
Probe, depth, co2, mV
II-2, 4cm, 3480ppm, 831
II-3, 8cm, 0.97%, 761
III-3, 8cm, 0.44%, 522

I still need a serial connector for the Soil CO2 data logger.

I need to seal the soil CO2 box and the solar charger box so that the wasps stop moving in.

Maybe should put a zero channel on the soil co2 logger.

There still might be a problem with the CNR1. Its wiring is:
Blue, red
Gray, yellow
White, black
Brown, green

The solar system read 12.9V, 4.5A solar, 4.1A load under cloudy skies.
