• Two aircraft campaigns – summer 2014, spring 2015 (spring 2016 in proposal)
• Close collaboration with Alfred Wegener Institute (Andreas Herber) and Environment
Canada. Additional collaborators (Johannes Schneider (MPI Mainz), Peter
Hoor (U of Mainz)
• NSERC-CCAR funding facilitates Canadian university participation in flights with the
POLAR aircraft, for the first time. As well, the funding has allowed for
expansion of the POLAR6 instrumental capabilities.
• With pooled resources (NETCARE, AWI, EC), the POLAR6 aircraft campaigns are more
extensive than originally planned: 90 hours in 2014 (60 in proposal), 110
hours in 2015 (60 in proposal). As well, the POLAR 5 will be flying in 2015 (110
hours) as part of PAMARCMIP for remote sensing studies.
• NETARE Co-Investigators Involved: Abbatt, Bertram, Blanchet, Jia, Martin, von Salzen
• Goals:
Summer 2014 – i. Influence of natural processes on Arctic aerosol, ii. Ship
Spring 2015 – i. Pan-Arctic study of aerosol properties (including black
carbon), ii. ice clouds (scavenging, formation, properties)
POLAR-6 Instrumentation in 2014
NOx, SO2, O3 (all standard, slow instruments)
CO (fast)
CO2 (Licor)
Particle size and number :
CPC (number of particles larger than 10 nm, fast)
UHSAS (70 nm to 1000 nm, fast)
SMPS (10 to hundreds of nm, slow)
Particle composition:
ALABAMA – single particle mass spectrometer – all species, semi-quantitative, large particles
SP-AMS – soot-particle aerosol mass spectrometer – sulfate, organics, BC, quantitative, > 100 nm
SP-2 – single particle soot photometer – BC (70 nm and up BC inclusions)
Optical properties:
CLAP (like a PSAP)
Droplet size and number: FSSP100, FSSP300 (fast)
Liquid water content: Nevzorov Probe (fast)
Ice Nuclei
Filters collecting particles for subsequent IN analysis (slow)
Sun photometer
Meteorological parameters
Dates - 2014
Topics for Discussion
Potential overlap with Amundsen, for ship emissions work. What do we do if the
Amundsen is not present?
Are there opportunities to study flaring, perhaps in 2015?
Typical flight profiles? How high should the profiles go?
The instrument complement is essentially fixed. How important would be fast
measurements of particle size below 100 nm? We may have the possibility of
using a U Denver CPC spectrometer to give us 1 s measurements down to a few
We are only doing “standard” gases. How important would it be to measure DMS
aloft, i.e. just a few grab samples per flight? Can we even do this?
Do we do science on the ferry flights?
One goal for the 2015 campaign is to assess how/if ice clouds scavenge BC. Use
of a counter flow virtual impactor inlet (CVI) might allow us to do that; we have all
the aerosol characterization instrumentation we need. Dan Cziczo (MIT) is
interested in collaborating on this. Is it possible?
