DAURE

This Wiki is a repository of information about a field campaign to be conducted at an urban/rural site pair in Barcelona and Montseny (Catalonia, Spain) in late 2008 and 2009.

Objectives

The objectives of this campaign is to characterize the sources of fine aerosols in the Barcelona region, with particular attention to carbonaceous aerosols. The campaigns should be carried out simultaneously at two sites, one inside Barcelona (CSIC) and the rural mountain site of Montseny (~25 km away), ideally with the same measurements at both sites.

Participant Groups

The following groups are likely to participate in this campaign, although in some cases this depends on funding.

• Host group: Xavier Querol's at the Institut de Ciencias de la Terra in Barcelona
  • Measurements: aerosol elemental composition (ICP-MS), OPC size distributinos, CO, NOx, O3, SO2, and meteorology (, RH, wind speed & direction, radiation, rain)
  • Funding is pending

• Jimenez group at the University of Colorado-Boulder
  • Measurement: High-Resolution Time-of-Flight Aerosol Mass Spectrometer (HR-ToF-AMS)
  • This will be potentially in collaboration with Eiko Nemitz's group at CEH Edimburgh
  • Funding is pending

• Laboratory for ATmospheric Chemistry at the Paul Scherrer Institut, Switzerland
  • Measurements: Filter-based 14C (of EC, OC, WSOC, WIOC) at both sites, and one High-Resolution Time-of-Flight Aerosol Mass Spectrometer (HR-ToF-AMS)
  • Molecular tracers and NMR spectral fingerprints (through collaborators in EUCARII)

• Several other groups have expressed an interest in participating, including:

• • Prof. Armin Hansel from University of Innsbruck, Austria, with the High-Resolution Proton-Transfer-Reaction Mass Spectrometer (HR-PTR-MS) for VOC detection
  • Prof. Phil Hopke from Clarkson Univ., US, with continuous EC/OC analyzers

Tentative Dates

Depending on funding and availability of personnel, we will conduct 1 or 2 campaigns. Ideally we would contrast summer and winter.

Confirmed dates

• 23-Feb-09 to 27-March-09, together with EMEP-2 campaign. PSI is available for sure and can bring HR-ToF-AMS. Also molecular tracers and spectral fingerprints.

Other tentative dates

• Alternative 1: Summer 2009
  • Tentatively the last 3 weeks of Jul-09 and first week of Aug-09, to catch a summer period. (Eiko has a campaign 8-June to 8-July 2009 in the Netherlands, which prevents moving this time period earlier in time, if his instrument is used).
  • Andre Prevot, 14-Dec-2008: We prefer a real summer campaign in 2009 over the autumn campaign during EMEP. The summer campaign could be anytime from May to August in our opinion.

We have to wait to fix the dates until we know the dates for the campaign in Paris which is part of the Megacity EU project MEGAPOLI. We can come to Barcelona before or after the Paris campaign. In the summer campaign we can bring the ToF and eventually the Q-AMS. If we have another AMS at one of the fixed sites, we might bring the Q-AMS in our mobile van instead of putting it at a fixed site. (Molecular tracers and spectral fingerprints will not be available)

• Alternative 2: Mid-Sep-08 to Mid-Oct-08, together with EMEP-1 campaign

Dates that don't work

• We had discussed May-08, simultaneously with the EUCARII-1 campaign in Europe. However Jose cannot make this time period due to a conflict in April-08 with the NASA ARCTAS campaign.

PSI has campaigns in Paris in Jan-Feb-09 and Summer'09 which may conflict with #3 and #4, but the specific dates of those campaigns had not been chosen when we last discussed this.
