The following video tutorials have been designed to give users an introduction to the HITRANonline website and to help make the most of data searches. The tutorials are separated into four major parts, which aim to introduce important features and document how to access and download the HITRAN data.

These tutorials can be viewed in order below and are also available through the HITRAN YouTube page.

Part 1: Introduction to HITRANonline

This video guides the user through the HITRAN webpages and explains each section of the database. Topics include: how to register, user settings, HITRAN database overview, supporting documentation and useful links.

Part 2: Accessing and downloading line-by-line data

These two videos guide the user through accessing and downloading line-by-line data. The first of these describes how to access line-by-line parameters from the HITRAN database in the traditional (160 character) HITRAN format. Topics include: parameter definitions, steps for selecting/downloading line-by-line data in the traditional output format.

Continuing from the previous video, the second tutorial of Part 2 gives further explanations of the standard (160 character) HITRAN format. Examples are also given for selecting by vibrational band and the output displayed for large data requests.

Part 3: Parameters beyond the standard HITRAN format

The next two tutorials introduce the selection of parameters beyond the traditional (160 character) HITRAN format. An example is first given for selecting parameters associated with broadening by "planetary" gases such as hydrogen (H2), helium (He), carbon dioxide (CO2) and water vapor (H2O).

The second video of Part 3 explains how to access line-by-line parameters for non-Voigt line shapes (e.g., Hartmann-Tran).

Part 4: Viewing and downloading absorption cross-sections

In this tutorial, we describe how to access and download experimental absorption cross-sections of different molecules. Topics include: searching for experimental absorption cross-sections, output file format and cross-sectional data contained in the supplementary folder of the HITRAN website.
