Summary: Standard field work, fixed auto rename run time, USC has been working here again.

Vaira
2012-09-19

I arrived about 7am with Siyan. It was clear, sunny and cool with little to no wind. The grass is still standing and golden. The trees still look mostly green.

USC was here again and installed at least one near sensor node west of the tower. They also made some modifications to the base station, but it still does not appear to be completely working.

Siyan did the standard field work and collected data.

We changed the run time for the program that renames the daily met files. It was running at 2 minutes after midnight and the last reading of the day was getting stuck on the front of the nest day. We changed it to run at 12 minutes after midnight.
