Description

This dataset contains the high-resolution H2 photo-absorption cross section of that is used in Chadney et al. (2021). The cross-section is composed from the following sources: - 0.1 - 80.4 nm: Backx et al. (1976) measurements, - 80.4 - 84.6 nm: Dalgarno and Allison (1969) + Yelle et al. (1993) calculations at 250K, - 84.6 - 120 nm: Yelle et al. (1993) calculations at 250K. For more information on this dataset, see Chadney et al. (2021).
