Summary: swapped 7500s, standard fieldwork

Where: Tonzi Ranch
When: April 9, 2004
Who: D Baldocchi, Nicole and Albedo

Swapped Irgas. Put sn 0042 on the floor system and removed sn 0073.

Ted put sn 0035 on the tower system.
Dropped 10-32 mounting screw. We need many spares of these at the field site.

The revised IRGAs have slightly new power wiring. These are being corrected.

Both floor and tower flux systems were operating.

Checked the soil CO2 probes and they were performing well.

There was lots of previous gopher activity near the open CO2 profile system. But rains over the winter has compacted the disturbance and looks like the gophers have moved on.

Mean grass height at Tonzi

109.5 mm +/- 42 mm, n =21
