Chance, K., and J. Orphal (2011), Notes Revised ultraviolet absorption cross sections of H2CO for the HITRAN database, J. Quant. Spectrosc. Radiat. Transfer, 112, 1509-1510, doi:10.1016/j.jqsrt.2011.02.002.

A revised set of temperature-dependent absorption cross sections for ultraviolet (UV) measurements of formaldehyde (H2CO) has been derived from two existing sets of laboratory cross sections, one using a Fourier transform spectrometer (FTS), and one using a grating instrument. This is conducted to satisfy the recommendation of the HITRAN Advisory Committee to provide a dataset with the spectral resolution and wavelength calibration of Fourier transform spectrometer measurements with the better intensity calibration that the grating measurements obtained. The re-scaled cross sections are now in the HITRAN database, and are recommended for use in atmospheric measurements and modeling, including photolysis calculations.
