HITRAN (high-resolution transmission) molecular absorption database, part of the Clouds, Water Vapour and Climate (CWVC) program

The aim of HITRAN (high-resolution transmission molecular absorption database) was to characterise the amount and wavelength-dependence of absorption by water vapour and other atmospheric species. It was part of the Natural Environment Research Council (NERC) funded Clouds, Water Vapour and Climate (CWVC) program. The dataset contains spectral line parameters derived from laboratory measurements on pure water vapour, and mixtures of water vapour and air. The measurements were made at STFC Rutherford Appleton Laboratory Molecular Spectroscopy Facility, and the line fitting was carried out by the Department of Meteorology at the University of Reading. The spectral line parameters are displayed in HITRAN format. Water vapour lines were fitted to the laboratory data in the spectral range 5037 to 5585 cm-1. These data are public.

HITRAN（高分辨率传输分子吸收数据库）的宗旨在于表征水蒸气及其他大气成分的吸收量及其波长依赖性。该数据集为自然环境研究委员会（NERC）资助的云、水蒸气与气候（CWVC）计划的一部分。数据集包含了从纯水蒸气和空气混合物在实验室测量中获得的谱线参数。测量工作于STFC Rutherford Appleton实验室分子光谱学设施进行，谱线拟合则由雷丁大学气象系完成。谱线参数以HITRAN格式呈现。水蒸气谱线在5037至5585 cm-1的谱段内与实验室数据进行拟合。这些数据为公共资源。
