DAURE

An easy to remember shortcut to this page is http://tinyurl.com/daure09.

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 "Determination of the sources of atmospheric Aerosols in Urban and Rural Environments in the western Mediterranean" and also for "Determinacion de origenes del Aerosol atmosferico en ambiente Urbano y Rural del Mediterraneo occidental". 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 be directly translatable to 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, and is carried out in collaboration with the EUCAARI European project.

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.

• Authorship policy for EGU-2010:  When submitting the abstract, please include in the author list the groups whose data you plan to use in their presentation. Typically include the student who has done the work and the principal investigator, and anyone else who has made a major contribution to that dataset. Then share the abstract with those groups, and they will let you know if they prefer to be listed in the acknowledgements (e.g. for small contributions) or whether anyone else needs to be added to the list. By the time the presentation is ready for EGU, you may be using other datasets and not using some of the ones you were planning to use. Just adapt the author list for the poster or talk with the principles above, and share a PDF of the talk or poster with your coauthors for their feedback. Note that if you have more than 10 authors, you will need to include the "DAURE Team" for the rest of the authors, as the form only allows 10.

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 and Other Sources

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:

• Network of the regional government ("Generalitat")
  • Link to download data from Generalitat
  • Further info on Air Quality from Generalitat

• Network from the City ("Ayuntamiento")
  • Some historical data up to 2007 are posted here
  • We don't have a working link for the city network yet (Pls let Jose know if you find it)

• Meteorological information and data
  • Weather information from MeteoCat
  • Link to download meteorological data
  • Upper air soundings

• Tools for back-trajectory calculations
  • FLEXTRA model from NILU
  • NOAA HYSPLIT

Sites

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

• Site BCN is 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 and it is located only 5 m away from BCN_1.

Urban Background

02° 6'58.06"E

(Decimal Coordinates: Latitude: 41.390003 Longitude: 2.116128

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 was at 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. Special 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.

• • Additionally there will be enough space to work with a conventional mobile unit (from PSI or from AQ local agencies. Note that at Montseny the unpaved mountain road is in poor condition, and has posed problems in the past.
