6. Approach to Task General
Evaluation of current and planned satellite observations of trace gases and aerosol on the basis of existing information
No processing of data or new simulations within this study
Starting point: findings on planned missions of the ACOR Final Report (April 2001, ESA 13048/98/NL/GD)

7. Approach to Task 1st Step
Review & update this on basis of more recent information (e.g. Odin, Envisat, Terra, Aqua).
Update assessments of individual sensors on basis of:
Data quality of sensors launched since ACOR FR
State-of-the-art simulations for planned sensors performed since ACOR FR
Consider requirements in combination
Constituents & other geophysical quantitiies
Precision, accuracy, vertical resolution, geographical & temporal sampling

8. Approach to Task 2nd Step
Synthesise information on individual sensors to gauge performances of missions
Draw findings for each application and identify key requirements which will not be met and so need to be considered in WP3000.
Review with User Group at MTR

Meets target Meets threshold Does not meet threshold

12. Approach to Task 8 estimated accuracy / instrument / height range:
2 x temporal sampling
2 x vertical resolution
2 x horizontal resolution
Threshold requirement and “best case” quoted for each
Actual resolutions will be indicated on plot
Colour bars scaled to altitude dependent requirements
Each requirement indicated (target on left, threshold on right, linestyle for category A,B,C)
