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)
Summary • FWHM: • FPA1 = Narrower than FM202-1 • FPA2 ~ FM202-1 • FPA3 & 4 = Broader then FM202-1 • Shape: Wavelength issues affecting?
