本文介绍了2016年版HITRAN分子光谱汇编的内容。新版本取代了2012年版的HITRAN以及其间的更新版本。HITRAN分子吸收汇编由五个主要部分组成：高分辨率辐射传输代码所需的传统逐线光谱参数、不适用于逐线形式表示的分子的红外吸收截面、碰撞诱导吸收数据、气溶胶折射率以及诸如普遍适用于数据的配分函数等通用表格。新的HITRAN在准确性、光谱覆盖范围、额外的吸收现象、新增的线形理论以及有效性方面都有了极大的扩展。此外，还增加了一些分子、同位素异构体和干扰气体，以解决地球以外大气层的问题。值得注意的是，数据库中新增了近300种在大气科学不同领域具有重要意义的分子的实验红外截面。该汇编可通过www.hitran.org获取。现在，大多数HITRAN数据已被转换为一种基础的关系数据库结构，与长期使用的基于顺序文本的结构相比，这种结构具有许多优势。新结构在很多方面为用户提供了便利。它能够为每个跃迁纳入一组扩展的基本参数、复杂的线形理论、方便用户定义的输出格式，以及非常便捷的数据搜索、筛选和绘图功能。还提供了一个强大的应用程序编程接口，该接口利用结构化查询语言（SQL）的特性，用于HITRAN的高级应用。由爱思唯尔有限公司出版。
This paper describes the contents of the 2016 edition of the HITRAN molecular spectroscopic compilation. The new edition replaces the previous HITRAN edition of 2012 and its updates during the intervening years. The HITRAN molecular absorption compilation is composed of five major components: the traditional line-by-line spectroscopic parameters required for high-resolution radiative-transfer codes, infrared absorption cross-sections for molecules not yet amenable to representation in a line-by-line form, collision-induced absorption data, aerosol indices of refraction, and general tables such as partition sums that apply globally to the data. The new HITRAN is greatly extended in terms of accuracy, spectral coverage, additional absorption phenomena, added line-shape formalisms, and validity. Moreover, molecules, isotopologues, and perturbing gases have been added that address the issues of atmospheres beyond the Earth. Of considerable note, experimental IR cross-sections for almost 300 additional molecules important in different areas of atmospheric science have been added to the database. The compilation can be accessed through www.hitran.org. Most of the HITRAN data have now been cast into an underlying relational database structure that offers many advantages over the long-standing sequential text-based structure. The new structure empowers the user in many, ways. It enables the incorporation of an extended set of fundamental parameters per transition, sophisticated line-shape formalisms, easy user-defined output formats, and very convenient searching, filtering, and plotting of data. A powerful application programming interface making use of structured query language (SQL) features for higher-level applications of HITRAN is also provided. Published by Elsevier Ltd.
