I arrived with Dennis, Siyan and Ana at about 11:30. It was sunny and hot with little to no wind. It is still green around the pond but very dry elsewhere though Dennis was noting about 20% VWC at depth.

Ana and I did an inventory of the OSU AirMOSS equipment which we have inherited. All three stations are still running and we got data back to February or May depending on the location and data file.

I added water to the soil co2 battery bank sn BB-TZ_soilco2. The batteries there are from November 2009.

I swapped both 7500s. At the floor sn 0042 came off and sn 0035 went on. At the Tower sn 0041 came off and sn 75H-2180 went on.
Floor 0042 read: 406.5ppm CO2, 523.0mmol/m3 H2O, 33.4C, 99.0kPa, 95.6SS
Floor 0035 read: 417.7ppm CO2, 458.6mmol/m3 H2O, 34.5C, 99.0kPa, 100.1SS
Tower 0041 read: 399.2ppm CO2, 482.3mmol/m3 H2O, 31.1C, 99.0kPa, 95.1SS
Tower 2180 read: 408.5ppm CO2, 401.2mmol/m3 H2O, 29.9C, 98.9kPa, 100.4SS

The Phenocam card had only 127 images again. I took the images off the card and put it back. I change the ftp timeout from 500 to 1000 in the Stardot scripts.

Dennis did the soil moisture. Siyan collected the met data, did the well measurements, serviced the z-cams and did midday water potential.

The ground where the IRT(TZ_irt 71) is oriented was cleaned, in order to measure bare soil temperature.
