HITRAN online

HITRAN is an acronym for high-resolution transmission molecular absorption database. The HITRAN compilation of the SAO (HIgh resolution TRANmission molecular absorption database) is used for predicting and simulating transmission and emission of light in atmospheres. It is the world-standard database in molecular spectroscopy. The journal article describing it is the most cited reference in the geosciences. There are presently about 5000 HITRAN users world-wide. Its associated database HITEMP (high-temperature spectroscopic absorption parameters) is accessible by the HITRAN website.

HITRAN（高分辨率传输分子吸收数据库）为一缩写，该数据库的编制源自SAO（高分辨率传输分子吸收数据库，简称HIgh resolution TRANmission molecular absorption database）。HITRAN在预测和模拟大气中光的传输和辐射方面具有重要应用。作为分子光谱学的世界标准数据库，其描述性期刊文章在地球科学领域被广泛引用，成为该领域的最常被引用文献。目前，全球约有5000名用户使用HITRAN。与之相关的数据库HITEMP（高温光谱吸收参数）可通过HITRAN网站访问。
