Summary: VPD measurements with LI6400.

We arrived around 10am, it was a sunny, warm, and clear day.

We took VPD response curves with the LI6400 for cattail and tule at West Pond wetland.

Elke and I took VPD response measurements on tule near the base of the tower with the Silver lab 6400 and the conifer chamber head. Measurements were taken on tule two leaves. Leaf temperature was controlled with measurements taken at three different temperatures, each set containing VPD measurements from maximum relative humidity to full scrub. Incoming CO2 was also controlled.

Daphne took VPD response measurements on cattail growing beyond the boardwalk with the Baldocchi 6400 and the opaque 2x3 broadleaf chamber with the LED light source. Measurements were taken on two leaves. Leaf temperature was controlled with measurements taken at three different temperatures, each set containing VPD measurements from maximum relative humidity to full scrub. Incoming CO2 and light level were also controlled.
