Notes:

Tommy and I arrived at 12:31pm; hazy, light wind, cool

Brought new calibration tank and NOAA tank for LGR calibration.

First connected remotely to LGR (didnâ€™t open top) to record tower inlet numbers.

Ran old cal gas (Praxair 400ppm) tank which is reading 100psi with 30psi on 2nd gauge (goes down to 25psi when flowing). CO2= 420.8; D13C=-43.0per mil

Next ran NOAA tank (CO2=407.7; D13C=-12.77 per mil).

Last ran new cal gas (New Praxair standard 400ppm) with 2nd gauge reading at 22psi when flowing; 1st gauge at 1650psi. CO2=408.3; D13C=-43.22 per mil.

*Forgot big wrench, may check and tighten gauge onto tank next time

Changed program back to sample ref gas for 300 s 2x per day.

Replaced filters on 3m and 5m inlets (bottom one looked ok)
