The purpose of this page is to serve as a repository of schedules and information for the participation of the Jimenez group in the ARCTAS campaign.

Personnel schedule on group calendar http://www.google.com/calendar/render.

Information on Phase I (past) is below for reference.


Summer Phase

Details to go here.

To-do List for ARCTAS

Immediate logistics/parts

  • Make basic loss calculations on inlet
  • (Buy new MD1)
    • test new pump in lab with needle valve for max obtainable flow
  • Check we have enough MCPs (2 sets)
  • Find 3rd TSI flowmeter
  • 300um orifice lead time (ML)

Data Analysis before summer (in approx order of priority)

  • Polish and send slides - b4 May 12th
  • Squirrel & submit test flights 1 & 2
  • Find description of Dibb inst. and size cut
  • Process fast data (Donna?) and resubmit with those
  • Generate PToF data:
    • Compare to Grimm, LARGE OPC+SMPS, SP2 OPC (>250nm) to evaluate size transmission
    • Evaluate whether the different slopes with light scattering are due to size distribution changes (F8)

Data analysis before summer, pending enough time

  • Evaluate the O/C data from Allison
  • Why are filter levels for Org (maybe also NO3, m/z 16) variable (TO/landing)?
    • is it mz29 or 44? Quantify in TT and squirrel
  • Implement the time-dependent CO2 and H2O corrections for the flights (or decide that they are not needed)
    • We can probably measure frag_org[18] directly in this way
  • Use plumes to align our data to others

Post ARCTAS-2

  • Repeat PCI transmission experiment

For Donna (in approx order of priority)

  • Improve Squirreling of the Fast Mode data (F4 and/or F5)

For Mike on non-immediate timescale, but before summer

  • Backup all plane software (incl LabVIEW,TD) on FTP site (including menus and .set files)
  • (Document inlet geometry and lengths), calculate residence time
  • Replot timetrace of all flights on "standard format", give copy to Jose for reference)
  • Install all plane software on Mike's laptop, so that his personal laptop can serve as backup for plane laptop in case of catastrophic failure, and test that it works
  • Start, mid-flight, and shutdown checklists
  • Check existing Igor code for offloading Grimm data (to intercompare the Grimm immediately after a flight)
  • Get BWP off c-ToF or JJ and test it (out of vac) to verify correct software operation

Instrument - Critical pre-CARB at Palmdale

  • Install MCP
  • Install MD1
    • Increase bypass flow on inlet line (now limited to ~2.5 lpm)
    • Change our inlet line to 3/8" to allow more flow if possible
    • If we can afford the pumping, replumb the Grimm to sample through a critical orifice
    • install TSI flowmeter on this pumping line (filter ahead), log flow
  • Install new Omega PID controller

Instrument - If enough time at Palmdale

  • Measure IE/AB over a full day (transient effects)
  • Fix 12 V power supply in TPS for preamp
  • Install HV supply for hard mirrow, so that we can run W-mode in forest fire plumes
  • (Waiting for Thomas about TPS error message: uups... / data crc / rx error: 5)
  • Get soldering iron with a finer tip
  • Connect UPS software for battery indication
  • Make sure we have a spare battery for thermocouple in plane
  • Get an install 2 bike cupholders

Before Summer Campaign

  • Be ready to submit data 48 hrs after each flight (24 better if possible)
  • Think whether to run at higher MCP and lower emission current for forest fires (less chance of missing threshold, reduce change of saturation in fires)
  • Stuff for Joel
    • Fix timetrace for Fast mode (SO4 goes down, others go up) -- already told him
    • Gaps of 5s in fast timetrace?
    • Timetrace of a few HR peaks as in flux mode?
    • Test and enable cell-phone filtering
  • See if we can buy/lease a spare TPS from Tofwerk
  • Bring spare laptop with everything installed, test that everything works, keep in plane
  • Have MichaelL ship He lecture bottle just before CARB
  • Investigate how we can refill the lecture bottle (ask Eric Apel)
  • Ask John whether AC-powered MD1 could run AMS (as backup?)
  • Put together leak detector with V70, controller, AC MD1, and SRS or Balzers RGA
  • Get more white HEPA filters



Integration Phase

(inclusive dates):

  • 2/22: Truck leaves Boulder with AMS and rest of kit
  • 2/29: Truck arrives in Palmdale,
  • 3/4: AMS onto plane
