Remote Sensing GroupGOME-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-

• FWHM:– FPA1 = Narrower than FM202-1– FPA2 ~ FM202-1– FPA3 & 4 = Broader then FM202-1

• Shape: Wavelength issues affecting?
