Last Week

• Worked with Todd on the CompLDV, learning how to
  use it and process data properly.
• Seeding problem was solved last week but it seems
  that the tent is hindering seeding.
• Sampling rate dropped significantly.
• I am guessing that using the tent and the suction
  blower prevents the seeding in the room air from
  going back into the tunnel.
• Cant stay inside lab for a long time while
  taking measurements.
• Took one profile and compared it to last summer
  measurements.
• Some differences in magnitude, probably because
  of different flow conditions, but same variations
  in overlap regions.
