Status: 27 October

Weather: Moist morning, drying out by afternoon with a light wind all day. Altostratus and altocumulus throughout.

Tasking:

• The morning data check showed few issues with EC150s and p4 but they all seemed to be morning dew related
• Squeegeed ISS 449 radomes
• Started sensor clean and guy wire tension check
• Also decided to perform a battery triage to determine which ones would be best to swap out when they finally arrive
• Matt arrived at his hotel in Champaign around noon, went and picked him up
• After lunch, started with a tour of the base trailer and ISS trailer
• Continued tour at the swale while finishing up the sensor clean and guy wire tension check
• When going over the data with cockpit in the sodar trailer, discovered lconv2 a2 1.5m CSAT3A was inop
  • It appeared to alternate between good data and empty values, switching every second or so
  • Power cycle failed to change this pattern
  • Ultimately decided to swap the sonic (2044 > 2045). Stream now looks good
• Went through a sonde launch with Andy and Matt

Today was my last day, Andy and Matt will be the crew on site for the next week. Good luck you two! There is an IOP tonight that was starting as we were heading out around 18:00 local. They are doing an earlier and potentially shorter one to try and beat the weather coming in tomorrow morning.
