Summary: Data collection, swapped 7500 head, water samples, measured eddy sensor positions

Mayberry
2013-07-10

I arrived about 10:15 with Laurie, Yanel and Cristina. It was clear, mild and breezy from the west northwest. I did not notice much change in the site since I was there last May 15th. Maybe the weeds around the tower are a little higher.

Gavin has deployed a bubble trap in the pond to the south of the tower.

I swapped the LI7500 Head, sn 2182 came off and sn 2150 went on. I pulled the USB stick, swapped the head, uploaded the new coefficients, reset the pressure coefficients (57.091, 15.210), pushed the reset button inside the 7550 box, and reinstalled the now empty USB stick. All seemed well. The new 7500 read:

396.3ppm CO2, 704mmol/m3 H2O, 95% Signal Strength, 21.5C, 101.37kPA

The 7700 read: 1.9ppm CH4 with ramps past 2.5ppm, 40 RSSI rising to 77 after cleaning

Cristina cleaned the solar panels. Water samples were collected.

The CO2 probe 1 was maxed out I think it is real.

I measured the position of the eddy sensors. Heights to centers are below and there is a photo with ruled square to get the north-south, east-west positions. There is a mark on the sonic mount to indicate true north.

HMP45 281cm agl
LI7700 303cm agl
Sonic 309cm agl
LI7500 308cm agl

Might take the long level and try to get a height of the ground under the tower above the water level.
