The HITRAN Atmospheric Workstation (HAWKS)

A new edition of the HITRAN molecular spectroscopic database and the high-temperature analog (HITEMP) have recently been released.1,2 They are included in a compilation called HAWKS (HITRAN Atmospheric Workstation). HAWKS represents more fully a “matter” database. Besides an updated HITRAN high-resolution molecular database of about one million transitions, there are files of aerosol indices of refraction, UV line-by-line and cross-section parameters, supplemental files of gases such as ionic species and ozone parameters suitable for atmospheric non-local thermodynamic equilibrium conditions, extensive IR cross-sections now at different pressures and temperatures, and molecular parameters suitable for modeling high-temperature radiance. In addition there is a moderate-resolution band-model code, MODTRAN3. There is also vastly improved software handling of the data in both WINDOWS and UNIX platforms, such as more sophisticated selection filters, plotting capabilities, pointers to significant references, and documentation.
