  1. AATSR visible/near-ir false colour image on 6 May 2010 MSG visible/near-ir + “dust” false colour images (12 UT) (not map-projected)

  2. Oxford-RAL Retrieval of Aerosols and Cloud (ORAC): Visible/near-ir/mid-ir retrievals from AATSR on 6 May 2010. Particle type Measured 11-12μm BT/K Simulated 11-12μm BT/K Liquid cld. Ice cld. Ash Effective Radius / microns Altitude / km

  3. SEVIRI Retrieval 6 May 2010 Liquid cld. Ice cld. Ash

  4. 9 May 2010 11:57UT This area processed

  5. 9 May 2010 11:57UT This area processed

  6. AATSR visible/near-ir false colour image on 9 May 2010 SEVIRI 12:00 (not reprojected to match lat/lon grid of AATSR)

  7. Oxford-RAL Retrieval of Aerosols and Cloud (ORAC): Visible/near-ir/mid-ir retrievals from AATSR on 9 May 2010. Particle type Effective Radius / µm Optical Depth Altitude / km Liquid cld. Ice cld. Ash

  8. SEVIRI retrievals (0.6,0.8,1.6,11,12,13 micron channels) – not same map projection !

  9. Next slides just to allow direct overlay of RGB,Phase,Re

  10. Where ash selected 11-12 micron difference good cf observations... AATSR-> SEVIRI->

  11. 8.7,11,12 “dust” RGBs Upper panels without 8.7 in fit Lower panels with 8.7

  12. 8.7,11,12 “dust” RGBs Upper panels without 8.7 in fit Lower panels with 8.7

  13. Upper panels without 8.7 in fit Lower panels with 8.7
