This Wiki is a repository of information about the DAURE field campaign to be conducted at an urban/rural site pair in Barcelona and Montseny (Catalonia, Spain) in winter and summer 2009. This is the main page about the study and focuses on the scientific aspects of the study. We have another Wiki page for the logistics and organization of the study.

Objectives

DAURE stands for "field campaign for the Determination of the sources of atmospheric Aerosols in Urban and Rural Environments in Spain" and also for "campanas de medida para la Determinacion de origenes del Aerosol atmosferico en ambiente Urbano y Rural de Espana. The objectives of the DAURE campaign is to characterize the sources of fine aerosols in the Barcelona region, with particular attention to carbonaceous aerosols.

State-of-the-Art methods such as 14C and HR-ToF-AMS analysis have been applied or are starting to be applied to the source apportionment problem in Central Europe, but not yet in the Mediterranean region. There are reasons to believe that the results from Central Europe (dominance of biogenic and biomass burning in the organic aerosol) may not apply in the Mediterranean, and this campaign is a unique opportunity to evaluate this hypothesis (CSIC, UC, PSI, CEH, BSC, UPC,CIEMAT, UB, UGR, and other participant groups). Furthermore, Biogenic Volatile Organic Compounds emissions and concentrations in Barcelona and Montseny and their implications as sources of aerosols will be also investigated (CREAF).

The campaign is also part of the EMEP Coordinated Winter Campaign.

Science Meetings

First DAURE Science Meeting on Mon. March 2, 10 am-1 pm at the main conference room at IJA (C/ Lluis Sole i Sabaris s/n, Barcelona). Short (10 min = 5-7 slides + 5 min discussion and questions) on the measurements / modeling being performed by each group, and the objectives of each group. This will help people to get to know each other and what each group will do during the campaign, and to know what previous data is available to provide context to our measurements.

Second DAURE Science Meeting on Tue March 10, 10:30 am at the main conference room at IJA.

Third DAURE Science Meeting on Tue March 17, 10:30 am at the main conference room at IJA.


Fourth DAURE Science Meeting on Tue March 24, 10:30 am at the main conference room at IJA.

As agreed at the 4th Science meeting, we will have at least 3 more Science Meetings focusing on data analysis:

  • Tue May 26 @ 10:30 am at IJA.
  • Another meeting TBD around Dec 2009 or Jan 2010
  • A meeting during the 2010 EGU Conference in Paris, France
  • Pictures from the campaign are posted here

DAURE-related Presentations at Conferences

Please send the abstracts of DAURE-related conference presentations to Jose for posting here, as this helps to keep track of the ongoing analyses from the different groups and the likely papers.

Data policy

From previous experience, it is important to share data early to identify instrument problems, early findings etc. We would like to propose the following data policy, which is based on that from MILAGRO and other large field campaigns. Please let us know of any suggestions for changes etc.

(a) Data will be shared during the field phase as soon as it is available (if possible the next day after it is taken for continuous instruments). We hope to set up an FTP site for this purpose within the next couple of days. This is done with the understanding that data is not fully calibrated/corrected/etc., and its main use is to look at trends and start to identify patterns and correlations at the different sites. Field data from other groups can only be used by people participating in the campaign, and CANNOT be shown or shared with people outside the campaign unless you have the permission of the data owners.

(b) Data should also be made available to all participants during the data analysis phase. Data from other groups cannot be used in presentations or publications without the permission of the data owners, and coauthorship should be offered to the data producers (which are then free to accept or decline the offer).

Data Server

We have created a secure FTP site to upload preliminary data and model results. You need a secure FTP program such as SFTP or SSH. A very good one for Windows is WinSCP, which you can download from this link. An equivalent free program for Macs is Cyberduck (recommended by Pete DeCarlo). Once you download the program, you need to set up a connection to cires.colorado.edu, and log in with "daure" and the password which Jose sent by email (pls request from him again if you've lost it). We have created a folder for every group, please load the data or model results there as they become available. An ASCII format would be best, please include the units, contact person, any data flags, etc.

To keep track easily of which data have been uploaded / will be uploaded / will not be available because of instrument problems etc., we have created another tab on the Google Spreadsheet, which can be viewed directly at this link. Please let us know about the status of the data which is currently in gray (unknown), or whether anything is missing, etc.

And finally, remember that the data is shared in accordance with the DAURE data policy, which is now official since no one has expressed any reservations about it.

Data from Monitoring Networks

There is an AERONET site in Barcelona which reports optical depth at several wavelengths during sunny days. The PIs belong to the BSC group which is participating in DAURE.

There are two monitoring networks in Barcelona, one operated by the regional government and another one by the city:

Sites

The campaigns should be carried out simultaneously at two sites of NE Spain in the Mediterranean Basin

General.jpgBCN MSY.jpg Perf1.jpgPerf2.jpg

  • Site BCN will be inside Barcelona (CSIC. Located in the university campus in the western side of Barcelona close to Diagonal Avenue, one of the main traffic roads from the city. In this area we will install 2 monitoring cabins BCN_1 and BCN_2. The first consits of a conventional aerosol monitosing site containing CSIC instrumentation. BCN_2 is a small office trailer ready to install the arriving instruments (power to be discussed) and it is located only 5 m away from BCN_1.

Urban Background 41°23'24.01"N 02° 6'58.06"E

BCN 1.jpgBCN 2.jpg

BCN 1&2foto.jpg

The station is located 10 m from a University Residence and around 300 m of our Institute of Earth Sciences ‘Jaume Almera’, CSIC. It is very convenient to book rooms at this residence a.s.a.p (see details below).

  • Site MSY will be a rural mountain site at Montseny (~50 km away), ideally with the same measurements at both sites. In this area we seleceted 2 monitoring sites MSY_1 and MSY_2. The first consits of a conventional aerosol monitosing site containing CSIC instrumentation. MSY_2 is a traditional rural house plenty of space, with sleeping rooms, kitchen and very basic labs. CREAF has ge kindly allowed us to use this MSY 2 field laboratory. Spacial thanks to Javier Retana (director of CREAF)for facilitating all sort of actions to allow us organizing the measurements. This is ready to install the arriving instruments (up to 10 kW) and it is located only 200 m away from MSY_1.

  • Barcelona Supercomputing Center (BSC)-UPC
    • Meteo and AQ modeling and forecast (CMAQ, WRF) Air Quality Modeling, CALIOPE project. The forecast is for the following 48 hours.
      • 1) Europe, 12 km grid cell resolution,
      • 2) Iberian Peninsula, 4 km grid cell resolution and
      • 3) area of Barcelona, 1 km grid cell resolution
    • Daily DREAM mineral dust model forecasts North Africa/Europe and East-Asia: BSC-DREAM
  • UPC
    • Lidar measurements for PM up to 5km (aerosols above 5 km might also be detected depending on their concentration). Each Monday (2pm solar time ± 1 h and sunset -2 h + 3 h) and Thursday (sunset -2 h + 3 h). Additionally, 2 more measurements/week around 01:00 UTC and 13:00 UTC, coinciding with CALIPSO passage over Barcelona.

ADDITIONALLY PLEASE PSI HAS TO CONFIRM:

    • Molecular tracers and NMR spectral fingerprints (through collaborators in EUCARII)

Dates

If sufficient funding and personnel are available, we will conduct 2 campaigns to contrast summer and winter at the paired urban/rural sites.

Confirmed dates in Winter/Spring 2009

  • 25-Feb-09 to 26-March-09 (period of actual measurements, together with EMEP-2 campaign.

Tentative Dates in 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 (Email on 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)"
