High-accuracy, compact database of narrow-band k-distributions for water vapor and carbon dioxide

An accurate and compact narrow-band k-distribution database has been constructed for water vapor and carbon dioxide from the HITEMP and CDSD-1000 spectroscopic databases. The systematic approach of k-distribution data generation and compaction, storage optimization and interpolation is discussed in this paper. The new database enables the user to obtain narrow-band, part-spectrum and full-spectrum k-distributions for inhomogeneous gas mixtures.
