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.

Abstract

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.

More Information (under review)

Introduction

The interaction of the atmosphere with near-IR solar (short-wave) radiation is dominated by water vapour absorption. Understanding and characterising the amount and wavelength-dependence of absorption by water vapour and other atmospheric species is essential for climate studies. Model calculations of radiative transfer in the Earth's atmosphere rely on molecular spectral lines databases such as HITRAN to provide information about the spectral properties of molecules present in the atmosphere.

The parameters are derived from laboratory measurements on pure water vapour and mixtures of water vapour and air. The measurements were made at the Molecular Spectroscopy Facility (http://www.msf.rl.ac.uk/) of STFC Rutherford Appleton Laboratory. The line fitting was carried out by the Department of Meteorology (http://www.met.rdg.ac.uk/) at the University of Reading.

The files contain data in HITRAN (http://cfa-www.harvard.edu/HITRAN/) format, and more details about the format and documentation can be found at their web site. HITRAN is an acronym for high-resolution transmission molecular absorption database.

Who to contact

If you have queries about these pages or about obtaining the CWVC-HITRAN data from the BADC then you should contact BADC Support (http://badc.nerc.ac.uk/help/contact.html). Your query should be answered within one working day. When follow-up work is required, the BADC support will carry out the work as quickly and efficiently as possible, and in any case, the user will be kept informed of progress.
