| COMMENTS: | JPl-2015(2015) recommendation:
The absorption cross sections σ(λ) and the temperature coefficients Γ(λ) of the linear parameterization of the temperature dependence
σ(λ,T) = σ(λ,298 K) + Γ(λ) × (T − 298)
reported 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. 105(D6), 7089-7101 (2000); DOI: 10.1029/1999JD901074,
were scaled up by 8% and averaged over 1-nm intervals
The consistency between the absorption cross section data of

in the range 300 to 360 nm demonstrate that the previously recommended absorption cross sections reported by Meller and Moortgat(2000) are too low by about 7–10% |
