• 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.

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 nm.
• 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?
