This dataset presents the results of a series of experiments conducted varying combinations of two versions of the HITRAN database (2016 and 2020) and two versions of the MT_CKD water vapor continuum model (3.2 and 4.1.1). Five atmospheric models representing different climatic conditions (Tropical, Mid Latitude Winter, Mid Latitude Summer, Sub Arctic Winter, and Sub Arctic Summer) are employed. Key atmospheric gases, including CO2, O3, CH4, CO, N2O, and O2, are prescribed at each atmospheric model. The dataset includes calculations with all gases present as well as experiments removing individual gases (specifically CO2, O3, and water vapor). Outputs consist of upwelling and downwelling infrared radiation and cooling rate profiles at 44 atmospheric heights from the surface to 95 km. Data are provided at 0.1 cm^-1 resolution across the spectral range from 10 to 3000 cm^-1. For each experiment, a file in “.txt” format is available at each atmospheric height containing the flux each wavenumber. This dataset offers valuable insights into the impact of different atmospheric compositions and models on radiative transfer processes and cooling rates, contributing to a better understanding of Earth's climate system.
