History and Future

GMC, Boulder, 17.-18.05.2016 2

IAGOS combines the advantages of MOZAIC and CARIBIC: IAGOS-CORE: Key components on many aircraft, every day with quasi-global coverage, 500 flights/ac/yr IAGOS-CARIBIC: Many species for a deeper understanding on one aircraft, ca. 50 flights/yr

Same instruments, regular QA/QC procedures (IGAS)

Objectives Scientific Value

  • Equip 20 longhaul aircraft with

scientific instruments for:

– chemical composition (H2O, O3, CO, NOx, NOy , CO2, CH4), – aerosol – cloud particles

  • Longterm deployment (20 yrs)
  • Global coverage
  • Open data policy (GEO/GEOSS)
  • Near-realtime data provision to

CAMS and Met Services

  • Monthly deployment of the

CARIBIC laboratory on board of 1 aircraft (Lufthansa D-AIHE)

  • Changes in the Tropopause Region

– Spatial and temporal resolution (background and trends)

  • Validation of Atmospheric Models

and Satellite Retrievals

– Tropospheric profiles of O3, CO, NOx, aerosol, CO2, CH4

  • Global Air Quality

– Influence of developing regions, biomass burning, climate change,...

  • International Transfer Standard

– Same systems everywhere – Regular Quality Assurance

Status of Fleet and Operation

  • 6 aircraft with IAGOS CORE rack (O3, CO, H2O, BCP)

– 2 DLH, 1 AFR, 1 CAL, 1 CPA, 1 IBE

  • 1 (DLH) with Package 2b (NOx) or Package 2a (NOy)
  • 7th a/c to be equipped in July 2016 (CAL)
  • 8th and 9th a/c in 2017 (CAL and AFR)
  • Negotiations with HAL for installation in 2017

=> 10 a/c equipped in 2017

  • STC for Package 2d (GHGs) in progress at EASA
  • IAGOS-CARIBIC container under major revision for

installation of new and improved instruments

IAGOS - CORE Instrumentation

Configurations for IAGOS-CORE aircraft:

  • Package 1 operates on all IAGOS-CORE aircraft (developed from MOZAIC)
  • Package 2 a-d (one option for one IAGOS-CORE aircraft)
  • NOy or NOx (P2a, P2b)
  • Aerosol properties (P2c)
  • Greenhouse gases, CO2 ,CH4 (P2d)

On 1 a/c On all 6 a/c EASA certification almost completed; P2a,b,c to follow

  • First deployment of

IAGOS-P2d with certification for HALO

  • System worked fully

autonomously throughout all flights

  • Results from pre-, post-

and in-flight calibration: Traceability to WMO standards verified

  • Data processing

automated

  • Ready for IAGOS

IAGOS Aerosol (Uli Bundke, Jülich)

IAGOS P2c

IAGOS P2c

– particle size distribution (OPC, > 250 nm) – integral number of particles (CPC; d> 5 nm) – non-volatile particle cores (CPC, TD; > 10 nm)

Installation scheduled for 2017 IAGOS P2e

P2e – Test Results Light extinction coefficient from P2e (CAPS PMex) compared to Lidar profile above Lindenberg. Good agreement with Mie calculations from size distribution. Future deployment of IAGOS P2e will provide global information on light extinction / AOD and complement AERONET / LIDAR observations. Uli Bundke, Jülich
