I arrived about 10am PST. It was mostly sunny and mild with little to know wind and high clouds moving in from the southwest. The trees looked barer than last week. The ground was dry and hard but there was some dew on the grass – more dew here than at Vaira.

The tram had derailed again. It ran just after I restarted it and I discovered that it was derailing because the wheels were too narrow for the track. Last time I fixed the wheels I added two shims to make the wheels more narrow because I though previously that the wheels were too wide. I removed one of the shims. Hopefully the wheels are just right now.

I installed the ATI sonic at the top of the tower. I moved the extra post from the west railing to the south railing. The ATI was mounted to the east of the Gill. I connected the ATI to the CR1000 on Com3. I removed the CF card, uploaded the new program and then inserted a new card. All seemed well. The new program has two new tables for the ATI data. Total fill time is about 45 days.

I swapped the battery on the CO2 profile CR10X. After restart a bunch of flags and ports were set. I reset the data logger’s clock and the reloaded the program and all seemed well. The LI800 had reasonable readings of about 420ppm.

I added relays to the soil CO2 system. I was hoping I could do all the probes with just two relays but I will need a third relay. I added a relays to the open and tree 2 probes. I downloaded the data from the CR23X and the CR10X before uploading new programs that control the relays. The probes now power up at 9min to 17min into the half-hour and data is logged from 14min to 17min.

I cleaned the z-cam windows – all had a smudge of dried water on them.
