Effective Emission Height

What exactly is meant by the term “Effective Emission Height (EEH)”?  It is often used to explain the greenhouse effect because, it is claimed, increased CO2 levels will raise the EEH to a slightly colder level, reducing OLR, and thereby … Continue reading

Updated CO2 Greenhouse Model

An Excel spreadsheet based written by Ken Gregory is now available which calculates the radiation flux based on the original model.  The spreadsheet is easy to understand and  can be downloaded here. Meanwhile I have been working to handle properly the temperature dependence … Continue reading
