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 winter and summer 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. 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).

Sites

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

• 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

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.

Regional background MSY_1: CSIC aerosol monitoring station 41°46'45.63"N 02°21'28.92"E

MSY_2: Rural house with laboratory for DAURE 41°46'45.21"N 02°21'17.48"E

• • Additionally there will be space enough 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.

• UPC
  • Lidar measurements for PM upto 5km high each Monday and Thursday. 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

• 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.

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)"

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.
• Alternative: Mid-Sep-08 to Mid-Oct-08, together with EMEP-1 campaign. However this may be too early for several of the groups involved, and too late meteorologically, as September is not as warm in Barcelona as the June-Aug period.

Logistics

• Accomodation

We recommend booking a.s.a.p accomodation at vthe following residence:

Residencia Torre Girona

Passeig dels Til•lers, 19

08034 Barcelona

Fax: (0034) 93 205 69 10

E-mail: torregirona@resa.es

Price of a single room:

1 month: 652 Euros (room only, without breakfast, you will have a small kitchen in the rrom) + 75 Euros contract for 2008. Additional fees: 12+35 Euros for water and electricity consumption IMPORTANT: WHEN BOOKING PLEASE MENTION THAT THE BOOKING IS IN THE FRAMEWORK OF 'DAURE' PRICES ARE MUCH REDUCED BECAUSE WE GET THE RATES FOR UPC UNIVERSITY STAFF, OTHERWISE IT IS MUCH MORE EXPENSIVE. 1 day: Single Monday to Friday 62.5 Euros, Week end 51.5 Euros [9]

Location: [10]

At Montseny there is free (very basic) accomodation if you bring sheets and a blanket or a sleeping bag. The rural house has central heating and a fireplace but this can not be used. We will get electric heaters. Telephone, water, power, beds, a basic lab, some offices and a kitchen will be available. We are trying to get internet there but this may be not possible. Cellular phones from Movistar get service there but Vodafone dont.

The main problem at Montseny is the access road (gravel / rock) which can be difficult, especially in case of snow.

Normal cars may have difficulties in travelling across this track.

Closest vilages to Montseny site are: Santa María de Palautordera and Sant Esteve de Palautordera. Restaurants and accomodation are available also overthere. Montseny is 1.5 h driving from Barcelona and 20 min from the above villages.

Issues to deal with

• Eiko Nemitz, email of 26-Nov-2007: "I would be interested to investigate the possibility to measure NH3 and HNO3 also. Modelling of NH4NO3 is still a major uncertainty in the European regional models, including the EMEP model. We could potentially loan a simple rotating wet denuder which fills hourly samples into test tubes for subsequent laboratory analysis for NH4+ and anions (HNO3, HCl, SO2). However, this would require laboratory analysis of 24 x 30 samples + some blanks for each month by some local lab. Is there a chance for the Spanish ministry to support this measurement?"

• Check water supply MSY

• Verifying power at MSY_2

• Rent a container for instruments and computers at BCN_2 (may be not needed if PSI brings trailer)

• 2 mobile units fro AQ monitoring booked at local AQ agency, but may be not needed if CSIC's cabins are equipped with instruments for gaseous pollutants (in progress).

• Booking 2 cars at CSIC for 15 Feb to 27 de March

• May be it is necessary to rent a pick up for transporting aerodyne to MSY

• CSIC does not has SMPS systems, solutions for this. May be we may buy DMA-Electrometrefrom TSI UFIPOLNET?????????

• Denuders fro OC for partisol: nned to build 2 of them

• Interesting having Radon measurements from UPC?

• Internet MSY

• AERODYNE Mini-AMS (50% possibilities)check if possible

• CLARKSON UNIVERSITY: Real time sulfate????? chek if possible

• CIEMAT: Nitrate, OC and EC real time check if possible

• GRANADA UNIVERSITY Column aerosol measurement instrumentation (CIMEL and others) check availability
