global wetland extent wetland methane modelling model inter-comparison project
2014/12/12
The Wetland and Wetland CH4 Intercomparison of Models Project (WETCHIMP) was created to evaluate our present ability to simulate large-scale wetland characteristics and corresponding methane (CH4) emi...
δ18O water isotope in the iLOVECLIM model (version 1.0) – Part 3: A palaeo-perspective based on present-day data–model comparison for oxygen stable isotopes in carbonates
δ18O water isotope LOVECLIM model A paleo-perspective present-day data–model comparison oxygen stable isotopes carbonates
2014/12/12
Oxygen stable isotopes (δ18O) are among the most useful tools in palaeoclimatology/palaeoceanography. Simulation of oxygen stable isotopes allows testing how the past variability of these isotopes in ...

The global middle-atmosphere aerosol model MAECHAM5-SAM2: comparison with satellite and in-situ observations
global middle-atmosphere aerosol model ECHAM5-SAM 2 comparison with satellite in-situ observations
2014/12/9
In this paper we investigate results from a three-dimensional middle-atmosphere aerosol-climate model which has been developed to study the evolution of stratospheric aerosols. Here we focus on the st...
A GCM Comparison of Plio-Pleistocene Interglacial-Glacial Periods in Relation to Lake El’gygytgyn, NE Arctic Russia
A GCM Comparison of Plio-Pleistocene Interglacial-Glacial Periods Lake El'gygytgyn Arctic Russia
2014/10/21
Until now, the lack of time-continuous, terrestrial paleoenvironmental data from the Pleistocene Arctic has made model simulations of past interglacials difficult to assess. Here, we compare climate s...
