7. Gas Retrievals: Tropospheric NO 2 Global coverage - GOME and SCIAMACHY sensors Target Uses –Trend analysis via monthly or annual means –Model input via NRT information Three algorithms being considered and compared –Possibility of downselection at project end –All may be kept if demonstrated niche uses found for each

8. Sample Products: Tropospheric NO 2

9. Gas Retrievals: Total Column SO 2 Global coverage - GOME and SCIAMACHY sensors Target Uses –Global trend analysis via monthly or annual means –Higher resolution for “hotspot” monitoring

10. Sample Product: Total Column SO 2

11. Aerosol Optical Thickness and Type Global Coverage Synergistic retrieval from daily acquistions of two sensors –GOME & ATSR-2 or SCIAMACHY & AATSR Target Uses –Global coverage and climatologies for monitoring –NRT retrievals over Europe as input to AQ models
