Weather was warm and sunny.

Last night there was an IOP.  We have not heard any word on how it went.  All our towers and sensors appear to have been functioning well though some sensors have slightly strange waveforms.

• The night frost and/or due seems to throw off the EC150 CO2 and H2O data.  I don't see a short term solution this.  Long-term, we may want to use the built-in heaters, though the power budget implications are not trivial..
• The Release tower Tsoil channel 2 (1.9cm) is noisy and showing signs of failing. 

Dan cleaned out the truck of all unnecessary items.  The generator is now being stored underneath the base trailer.

Hendrik spent time on the phone with Univ Cordoba students who have been doing an ops trip.

We received 6 solar panels from Boulder today, shipped air.  We began the process of swapping P6's 65W panel for a 145W panel.  Then, Dan had a better idea of doing this swap at Release.m, UConv.m, and LConv.m, where we're actually negative in the power budget.  Gary's ubiquity-power-cycle fix eliminated the need for additional charging at the pressure stations.  However, we still need more charging at the sites mentioned above.  We will begin this swap tomorrow.

Agenda for tomorrow

• Swap in 145W panels at Release.m, UConv.m, and LConv.m
• Give April 5-min avg geo/tilt-cor data from 10/12 - 10/17 (for her and U of W students.  Covers 2 IOPs)
• Finish EC5 soil experiment. 
• Meet with Andy, who arrives in Champaign at 5PM
• Hendrik's last day in Champaign.
