• Can Annual Irradiance = Annual Enthalpy? If So, What Does It Show About Climate Change
  This mathematical exercise was done to see how close calculated irradiance would come to measured irradiance and to prove that climate models using enthalpy instead of radiation or irradiation were valid.  (The CRGW (3) model is a enthalpy based model). ...
