Infrared Backradiation under Low Humidity Conditions: An Evaluation of Greenhouse Gas Impact Ernst Hammel, Martin Steiner, Robert Glaubauf This study examines the impact of greenhouse gases (GHG) on infrared back radiation (IRBR) in extreme desert and midlatitude winter conditions. Employing MODTRAN simulations, pyrgeometer measurements and energy balance fit models, we assess the impacts of CO2, Argon (Ar), N2O and R-134a.

CO2 sensitivity studies under laboratory and outdoor conditions as contribution to climate change discussions  The EU considers climate change as an existential threat and wants to reduce net greenhouse gas emissions by at least 55% by 2030 and down to 0% by 2050 within the “EU Green Deal” and economic growth should be decoupled from the use of energy resources.
