Abstract

Correspondence to: Roland Eichinger (roland@dgf.uchile.cl) S1 IntroductionThis supplement provides additional material to the article "An improved land biosphere module for use in reduced complexity ESMs with application to the last glacial termination". We provide a detailed description of our treatment of the new vegetation dependent albedo, the dust radiative forcing and high latitude ocean iron-limitation and present an example case for the snow and ice line parameterisation that interacts with the new biosphere scheme. Next, we give the mathematical description of the 5 ocean vertical diffusion profile function in the high latitude model ocean that is applied for generating Last Glacial Maximum (LGM) conditions in the DCESS model and the formulation of the resumption of deep ocean mixing. Furthermore, we present some additional information on the generation of model LGM conditions in atmosphere and ocean, a literature review on the Mystery Interval (MI) and an overview for model and proxy data changes during the MI. The Supplement ends with additional information on the various 14 C production rate time series that were applied in the model simulations, an analysis of the DCESS 10 model calculated 14 C production rate time series and the isotope ratio definitions.
