Kerridge, B.J. et al., 2001: Definition of Mission Objectives and Observational
Requirements for an Atmospheric Chemistry Earth Explorer Mission, ESA/ESTEC
Contract No. 13048/98/NL/GD, Final Report.
The objectives were, firstly, to define mission objectives and observational
requirements for a mission commencing in 2008 and, secondly, to assess
systematically the observational capabilities with which to address these
June 2000: A call for 'Earth Explorer Core missions' was released by ESA.
Overview of ESA Earth Explorers
Autumn 2000: 5 mission proposals were selected for further investigation in
the assessment round. Among them was the ACECHEM (Atmospheric Composition
Explorer for CHEMistry and climate interaction) mission, which was proposed
by a consortium of thirteen European institutes, led by RAL.
A "Scientific Preparatory Group" (SPG) led by ESA, with among others
H. Kelder as member and M. van Weele as contribution scientist, investigated
further the scientific merit of this mission.
In support of the scientific assessment, a consortium led by RAL conducted
the "ACE" (Atmospheric Chemistry Explorer) study.
30+31 October 2001: all Assessment Reports have been presented on the "Earth
Explorer User Consultation Meeting" in Granada, Spain. Three missions have
been selected for the "Feasibility Study" phase, but ACECHEM was not
selected. More information on the Earth Explorer User Consultation Granada
In the end, the Earth Clouds Aerosols and Radiation Explorer (EarthCARE)
proposal accepted as the Core mission of this selection round. It is
currently due for launch in 2015.
This project is a cooperation between the two KNMI departments
