Scattered clouds with the usual temperatures and winds

Onsite: Gary, Matt, Steve (also for ISS)

Started the day by seeing the Solar Concentrator turn on at sunrise.

Outside work:

  • Matt started the Leica scans that show us pretty close in setting stuff up.  Boom angles are generally within 1 degree of design.  tt heights are within 35cm of designed.
  • I dressed the new t0 with hotfilm cables.  Later, Gary installed some probes.

Trailer work:

  • Found the bug in profile.plot() that wasn't averaging data, causing odd profile plots.  Now we begin to see that indeed 7m seems to be a bit low, presumably due to flow blockage by the lower tt tower structure.  Mack is bringing a couple of the long scaffolding booms from CME04 that we'll try to install on Monday.  Reran webplots back to 16 July.
  • Tested the spare CSAT3 some more and had 4 periods where up to 10 samples were dropped, during the heat of the day.  I guess I'll declare it a working spare.
  • Matt did dry soil core weighings for t49 and t23.  Still haven't taken t2.
  • Also did a quick analysis of w'w' across the array and confirmed that the different models of sonics see different amounts of variance.  There is good agreement within each type.  Variances from the CSAT3As are the highest, CSAT3Bs a bit lower by about 5%, and CSAT3s even lower by about 15%.  I note that this is the order of the sampling rate, and thus the bandwidth.  Not sure yet if something else is going on.
