Summary: IRGA not reporting CO2 or H2O, Standard fieldwork

I arrived at about 9:30 with Siyan. It is still dry and dusty but the litter was knocked down a little and it is not so crispy due to a little rain about a week ago. The trees look better because their dead leaves were knocked off by the rain.

I collected the data and Siyan did the regular fieldwork including clip plots.

The 7500 read: **.** CO2, **.** H2O, 99.34kPa, 16.54C, 0.00SS
I tried reseating the cable to the IRGA head and it read reasonable numbers for a few minutes before falling back to the null values. I didnâ€™t see anything else wrong â€“ no errors reported. Maybe a dead source lamp? Iâ€™ll try to get out next week to swap it out.

We went to the pond. The water level is below the last staff gauge. Iâ€™ll also try to put in one more lower gauge before it rains again. Cows have been working over the edge of the pond.
