Meetings
15th - 17th February 2012: We held our kickoff meeting at the LBA offices at INPA in Manaus, Brazil. Material from this, including presentations and minutes can be found here (restricted access).
2nd - 3rd July 2012: The follow-up meeting was held at the University of Manchester, UK, involving both UK and Brazilian stakeholders. Material and notes from this meeting can be found here (restricted access).
BUNIAACIC pump priming deployment
In order to meet objectives (iii) - (v), we are planning a short-term intensive deployment of instrumentation from the University of Manchester's Centre for Atmospheric Science, likely to take place in the middle of 2013, probably located at the TT34 site north of Manaus (to be confirmed). Non-refractory particle chemical composition will be measured using the High Resolution Aerodyne Time of Flight Aerosol Mass Spectrometer (HRToF- AMS) for direct comparison with that measured by the long-term ACSM. A Hygroscopicity Tandem Differential Mobility Analyser (HTDMA) will measure particle growth factors (< 10% to 90% RH) and assess the mixing states of the aerosol. Cloud droplet activation potential of size resolved particles will be derived from a CCN counter sampling monodisperse aerosol from a Differential Mobility Particle Sizer (DMPS), from which the dry aerosol size distribution will also be recorded. A Multi Angle Absorption Spectrometer (MAAP) will quantify the contribution of black carbon (BC). A WIBS-3 dual channel UV fluorescence instrument will be used to detect bioaerosols, primary biogenic particles which may significantly contribute to organic aerosol mass and coarse mode and IN number. The instrument will provide rapid realtime measurement of the number size distributions of total and biologically-derived particles. This intensive deployment is intended to act as a pump-priming activity for the development of further larger-scale collaborations, most likely through a consortium proposal.
