Future Mission Studies: (ON) TRAQ
(ON) TRAQ study (28 April 2008 - 15 January 2010), Original and New TRopospheric composition and Air Quality measurements. Conducted for an assessment study for "ESA Future Earth Core Explorers Mission" candidate "TRAQ".

Full ESA name: "TRAQ Performance Analysis and Requirements Consolidation for the Candidate Earth Explorer Mission TRAQ (TRopospheric composition and Air Quality)

The key objective of this preface-A study was to support the scientific development of the candidate Earth Explorer Mission TRAQ in parallel to the industrial phase 0 system study for the candidate mission TRAQ. This project further supported the TRAQ MAG and ESA for the prioritisation of the challenging mission requirements and has provided recommendations to update the Mission Requirement Document (MRD).

  1. 15 March 2005: A call for 'Core Earth Explorer Ideas' was released. More information: ESA Future Missions .
  2. 15 August 2005: Following the call for ideas, a consortium led by KNMI proposed the TRAQ mission.
  3. during 2006: The TRAQ mission was selected as one of the six missions which would be investigated further in the assessment round. More information: ESA Candidate Explorers - Assessment Phase .
  4. A "Mission Assessment Group" (MAG) led by ESA, with among others P. Levelt and H. Eskes as members, investigated further the scientific merit of this mission.
  5. In support of the scientific assessment, a consortium led by KNMI conducted the "ON TRAQ" study.
  6. 20-21 January 2009: all Assessment Reports have been presented on the "Earth Explorer User Consultation Meeting". Three missions have been selected for the "Feasability Study" phase, but TRAQ was not selected. More information and all assessment reports: Earth Explorer User Consultation Meeting .
  7. Despite the fact that TRAQ was not selected early in 2009, the ON TRAQ study was finalised normally.

The ON TRAQ consortium, led by KNMI, consisted of the following institutes and universities:
  • Belgian Institute for Space Aeronomy (BIRA-IASB)
  • Environment Canada
  • Finnish Meteorological Institute (FMI)
  • Royal Netherlands Meteorological Institute (KNMI)
  • Laboratory for Atmospheric Optics (LOA, a joint laboratory of University of Lille - 1 & CNRS)
  • Laboratory of Molecular Physics for the Atmosphere and Astronophysics (LPMAA, a joint laboratory of University Pierre et Marie Curie & CNRS)
  • Noveltis
  • Netherlands Institute for Space Research (SRON)
  • Free University of Brussels (ULB)

This project is a cooperation between the two KNMI departments KS-AK and KS-CK
