| COMMENTS: | Using the high-resolution absorption cross sections reported by C.A. Cantrell, J.A. Davidson, A.H. McDaniel, R.E. Shetter, and J.G. Calvert, "Temperature-dependent formaldehyde cross sections in the near-ultraviolet", J. Phys. Chem. 94 (1990) 3902-3908; DOI: 10.1021/j100373a008, and 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 (2000) 7089-7101, DOI:10..1029/1999JD901074, a revised set of temperature-dependent absorption cross sections has been derived The cross sections of Cantrell et al. have been re-scaled in intensity to the cross sections of Meller and Moortgat The linear temperature dependence is given by σ(T) = A + B × (T - 273.15) and by the listed parameters A and B The data have been obtained by personal communication from K. Chance (March 2012) |
