Summary: Changed filters on LGR inlets

I arrived around 2:30pm, it was clear with a light breeze. Lots of spiderwebs. I have noticed the LGR main tower inlet has been giving strange numbers and low pressure over the past week so I wanted to come and check on it. The filter was really dirty so I swapped it out and the numbers/pressure became reasonable again.
I also checked the lower inlets and the 3m inlet looked a little dirty too so I swapped it out. The 1.5m inlet looked fine.
Cal gas is now at 150psi.
I also made a slight adjustment to the laser for better alignment with the D13C peak. laser voltage before adj=2.036 after adjustment=2.040.

The brown tarp had a small hole in it already which I patched with electrical tape-may need to replace tarp soon.
Finally, I downloaded data.

CO2=412.3 ppm
D13C=-10.96per mil
D18O=-46per mil
H2O=316ppm
gas temp=44.86C
gas P=119.78torr
laser response=12.87 microsec.
