I arrived about 9:00 with Joe and Madeleine. It was clear, sunny and warm with a light breeze. The pepperweed is flowering but the field seems slightly browner than last week.

The LGR read: 21.77C, 133.0Torr (145.2 after adjusting), 14.74usec, 10Hz, 1.881ppm CH4

The 7500 read: 16.22mmol/m3 CO2, 680mmol/m2 H2O, 101.26kPa, 21.75C, 249diag

The LGR seemed slow so Joe restarted it. In slow flow mode the pressure was decreasing towards zero.

Joe downloaded the soil CO2 data so that Patty could check the data since she replaced a few probes last week and wanted to make sure everything looked good. Joe also noted that probe #3 at set B seemed high.

I did spectral measurements. Joe and Madeleine did moisture point and well depth and Madeleine measured veg height.
