Beyond-Voigt collisional parameters of subTHz H 2 O lines for atmospheric applications

Key Points

• Collisional parameters provide critical data for understanding atmospheric conditions, particularly related to water vapor.
• Key measurements show significant variability in absorption coefficients across different subTHz frequencies.
• Analysis of molecular interactions offers insights into how water vapor behaves in the atmosphere during various processes.
• This work supports improved atmospheric models; external validation in real-world conditions may be necessary.
