AROMAT-1: Airborne Measurements of Aerosols and Trace Gases in Romania

The AROMAT-1 campaign aimed to test newly developed airborne instruments for air quality research and prepare for upcoming intercomparison and S5P validation campaigns in Romania. The campaign included various research institutions and utilized both airborne and mobile platforms for measurements.

Presentation Transcript

  1. AROMAT 1 (Sept 2014) -> test new instruments • AROMAT 2 (Aug 2015) -> prelaunch campaign • AROMAT 3 (Summer 2017) ? -> Tropomical/val campaign

  2. The AROMAT-1 team ACC-11, ESA-ESRIN, Frascati, 28-30 April 2015

  3. AROMAT-1: Airborne Romanian Measurements of Aerosols and Trace gases • ESA campaign coordinated by BIRA (Belgium), including 7 other research institutions Uni. Galati, INOE, INCAS, (Romania), IUP-Bremen, Uni. Berlin, MPIC (Germany), KNMI (The Netherlands) • Aim: test newly developed airborne instruments for air quality research and prepare forthcoming intercomparison/S5P validation campaign in Romania Constantin et al., TSWJ, 2013 • First week in Bucharest • (largest city in Romania, with 2.2 million pop., heavy • traffic ) • Second week in Turceni: small village in the • countryside but with a very large power plant know • to be a major source of NOx,SO2 and aerosols • -> Both spots visible on OMI data Turceni

  4. Instruments and platforms Airborne: -Uni. Berlin Cessna: -> Sunphotometer and Microtops (Uni. Berlin) ->AirMap (IUP-Bremen) -Weather balloons -> NO2 sonde (KNMI) -INCAS UAV -> Dust trak (INCAS) -> Aerosol particle sizer (INOE) -Uni. Galati UAV ->SWING (BIRA) ->NO2 sonde (KNMI) Mobile (car-based) -Mini-MaxDOAS (MPIC) -Zenith-only mobile DOAS (Uni. Galati, BIRA) -Double channel mobile DOAS (BIRA) -NO2 sonde (KNMI) • Static/Movable • -RADO observatory (Bucharest): lidars, in situ monitors, Aerosol Chemical Speciation Monitor, meteo. Station, PM 2.5, Aethalometer, CIMEL sun photometer (INOE) • -In situ monitor (Uni. Galati) • -In situ monitor, scanning lidar, ACSM (INOE) NO2SO2aerosols

  5. Bucharest: Measurements from RADO Observatory (INOE)lidar and aerosol chemical speciation monitor Ref for RADO: Nicolae et al. 2010, RRP, 2010

  6. Bucharest: Mobile DOAS intercomparison (NO2 dscd) Mobile DOAS systems: compact uv-vis spectrometers on board cars, zenith only for the intercomparison MPIC system: Wagner et al., AMT, 2010 BIRA: Phd Merlaud, 2013 Uni. Galalti: Constantin et al., Sensors, 2013 Sept 2, 2014, around Bucharest Sept 3, 2014, around and in Bucharest

  7. Bucharest: Measurements from INCAS UAVAerosol size distribution at ground and at 1 km alt

  8. Bucharest: Simultaneous AirMAP and MobileDOAS NO2 measurements AirMAP: IUP-Bremen pushbroom imager with 48° fov, resolution 100m from the Uni. Berlin Cessna Ref: Schönhardt et al., AMT, 2014 Sept 2, 2014, around Bucharest

  9. Turceni: NO2 sonde measurements 11 launches on balloon in Turceni Ref KNMI sonde: Sluis et al., AMT, 2010

  10. Turceni: NO2 SWING-UAV measurements Ref SWING-UAV: Merlaud et al., ESA proc., 2013

  11. 10 SEPTEMBER 2014 TURCENI-CRAIOVA TURCENI SO2 ISALNITA CRAIOVA

  12. AROMAT-2 : Aug 17 to 29, 2015 Same partners + VITO and DLR (APEX), NILU (SO2 camera), ESA mobile lidar team INCAS BN-2 Aerosol particle sizer CAPS KNMI sonde Uni. Galati Ultralight UV-vis spectro in nadir KNMI sonde DLR DO-228 APEX + SO2 camera in the cessna in parallel with AirMAP

  13. New Experiments in Bucharest - Mapping NO2 with Cessna and AirMap together (intercomparison) - Mobile DOAS intercomparison (H2CO) • Sounding bn-2 for aerosol and NO2 profiles • Pandora at INOE (but no more UAV in Bucharest) New Experiments in Turceni • NO2Profiles with the glider • Intercomparison and tomography with SO2 camera • Mobile DOAS intercomparison (SO2) • Aerosol profile with ESA lidar (but no more balloon in Turceni)

  14. AROMAT-3? S5P cal/val campaign (late summer 2017) Objective: evaluate the ability of TROPOMI to resolve NO2 distributions at inner-city scale, and at even smaller scale (emission plumes from powerplants). ->two targets: Bucharest and Turceni(?) ->longer term operation of ground-based systems to collect more validation data.In Bucharest (core period of the campaign): static and mobile ground-based systems, together with aircraft instruments to map the horizontal distribution of NO2 (AirMap and APEX). MAXDOAS, Lidar, NO2 in situ sondes for vertical distributions of NO2 and aerosols Ground-based systems at several places inside and around Bucharest for reference points in the map. For Turceni: ? (is it a good place for satellite validation?)
