Summary: Fixed co2prof vs irt file name conflict, measured equipment locations, cows around, repaired cow fence at soil co2

Daphne and I arrived at about 11:15. It was clear sunny and warm. We got a little rain last week but things still look dry here. The trees have started to put on leaves. About half the trees have new leaves but it is kind of patchy with the trees directly northwest of the tower mostly still bare.

I collect data at the Tower. Loggernet had written about 900 one-line files containing data from the Vaisala co2 profile and the original IRT system. I saw this starting to happen before I left last time but couldnâ€™t figure out why. Apparently I somehow name both data files the same. Loggernet was smart enough to figure out that the data was different and started a new file each time it collected data. Otherwise things seemed fine. Daphne helped me make a bunch of equipment location measurements around the tower.

The 7500s read:
Tower: 429.8ppm CO2, 457.0mmol/m3 H2O, 98.6kPa, 17.0C, 102.6SS
Floor: 432.4ppm CO2, 499.2mmol/m3 H2O, 98.6kPan 20.6C, 99.3SS

I collected the rest of the data from the data loggers including the FD chambers. The lithium power pack at the Road Well still seemed okay - it was slightly below 12V but only one charge status light had gone out. I left it in place especially since the water level is still below the sensor.

Daphne did the Moisture point, wells, DBH, and serviced the z-cams. We repaired the cow fence around the soil co2 system. There were cows hanging out at the water container when we arrived.

We left about 14:30
