COMMENTS: Absorption measurements using the SCIAMACHY PFM (scanning imaging absorption spectrometer for atmospheric chartography pre-flight model) spectrometer

Vacuum wavelengths 247.3-400 nm; resolution 0.21-0.22 nm; 1383 data points

Spectral regions are cut and concatenated at 311.7 nm and 355.6 nm

The data are scaled to the absorption cross sections measured by

R. Meller and G.K. Moortgat, "Temperature dependence of the absorption cross sections of formaldehyde between 223 and 323 K in the wavelength range 225-375 nm," J. Geophys. Res. D 105, 7089-7101 (2000); DOI: 10.1029/1999JD901074
