  2. GOME-2 FM202-2: PM2Slit function analysis • Overview of slit-function fitting method • New results for FM202-2 (WP2100) • - use of new angular parameters from TNO • - modification of source line shape to match commissioning measurements • Comparisons of results: • - FM202-2 to FM202-1 • - FM202-2 1mm to FM202-2 0.5mm • Error analysis for FM202-2 • Discussion re next steps, date of next meeting (FP) • AVHRR/GOME-2 co-location, spatial aliasing and geo-referencing (Ruediger Lang)

  3. Bad data points

  4. Wavelength out over band? Correct wavelength?

  5. Banding? & bad data?

  6. Banding? Bad detector pixels

  7. Ghosts correct?

  8. Reflected ghost?

  9. 1 mm slit functions 1 mm slit functions

  10. Use extreme angles?

  11. B1 & B2 extreme angle wls problem

  12. B2 ~323-330nm

  13. B3 good example

  14. B4 good example
