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
• 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
