Mayberry
2013-04-11

I arrived about 10:15 with Laurie. It was clear, mild and windy. The cattails and tules continue to green up. The weeds on the check levees seemed to have doubled in size. There are goats on the Mayberry slough levee clearing brush. Places that have been processed by the goats look as if a bomb has gone off.

All was well at the tower. The 7700 read 1.9ppm CH4 with an RSSI of 41. The RSSI climbed to 72 after cleaning. The 7500 read:
391ppm CO2, 553mmol/m3 H2O, 29.8AGC, 18.72C, 101.62kPa

I topped off the 7700 wash reservoir. There are still wasps in the box and some algae growing in the bottle. We will have to clean it out soon.

We did not bring waders but I service the Tule tower last week and was able to collect the data with the radio link. Seems I did not connect the TC associated with the Tule co2 sensor its reading INF. But the CO2 values looked okay.

I did not fix the LI7550 clock settings. Next time we need to change the 7550 to run on UTC time.
