HITRAN Database

The HITRAN database is a comprehensive scientific resource that contains detailed information about how different gases absorb and transmit light, especially in the infrared and microwave regions. It is used by researchers and engineers to understand and simulate how gases behave under various conditions, such as in Earth's atmosphere, stars, or spacecraft. By providing data on molecular absorption lines, HITRAN helps improve climate models, remote sensing, and spectroscopic measurements. Essentially, it acts as a reference guide to understand how gases interact with light, which is crucial for studying the environment and planetary atmospheres.
