Abstract:In the 2016 meeting we reported our experimental linelist of NH$_3$ in 50-660 cm$^{-1}$ (See Paper FE08). The retrieved line positions and intensities were used as standards to validate HITRAN 2012 database and our empirical Hamiltonian models (Yu et al. 2010; Pearson et al. 2016). While the line position comparisons with HITRAN and our Hamiltonian models were excellent, the intensity comparisons were less satisfactory. During the past two years, we have updated our Hamiltonian model to improve the intensity prediction. In this presentation, we will report our significant improvement on intensity predictions, especially for the $\Delta K=$3 forbidden transitions. We will also report comparisons of HITRAN 2016 with our existing experimental spectra.
