1 CAPACITY Progress Meeting 2 KNMI, 7 April 2004
Brian Kerridge Victoria Jay Richard Siddans Barry Latter Jolyon Reburn Remote-Sensing Group Atmospheric Science Division, SSTD Rutherford Appleton Laboratory

2 Content Assessment of Existing and Planned Missions and Networks (WP2200) Outline of Work Packages Approach to the Task

3 Work Packages WP2210 Co-ordination WP2220 Assessment of ground networks WP2230 Satellite observations WP2240 Conclusions

4 Ground Networks WP2221 Trace gases WP2222 Aerosol

5 Satellite Observations
WP2231 Nadir-uv/vis/nir WP2232 Passive nadir-sounding of aerosol WP2233 Nadir-mir WP2234 Lidar WP2235 Limb-mm/sub-mm WP2236 Limb-mir WP2237 Limb-uv/vis WP2238 Occultation WP2239 Integrated missions

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

9 Approach to Task Presentation of Findings Graphical Tabular

10 Approach to Task

11 Approach to Task Meets target Meets threshold Does not meet threshold
Instrument A Instrument B Instrument C Error Troposphere UTLS Stratosphere Vertical Resn Horizontal Sampling Temporal Sampling 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)
