DynaMOS intends to make a significant contribution in reducing uncertainties of the
soil carbon reservoir estimates and better evaluate soil carbon dynamics at the 0-10 years and 10-1000 years time-scales. DynaMOS aims at both acquiring new data and providing new generations of soil carbon dynamic model by introducing soil organic
matter chemistry. It is based on stable and radioactive carbon isotopes determinations
on specific compounds and valorization of ORE databases. Different experimental
environments are considered to get the most appropriate data and to ensure the constrains on model input: C3/C4 vegetation change, 13C and bomb 14C-labeling to
constrain the time factor, natural constant beech forest to get global and molecular
13C fractionation associated to degradation and well-known soils to model organic
matter vertical distribution.
DynaMOS is ambitious and offers a high level of genericity in four of its aspects:- It
proposes advances at the same time on the three fronts of methodologies,
mechanisms understanding and modeling.- it takes into account most of the
biochemical families together in a single concerted study on same sites.- it takes into
account the carbon fate on the whole timescale from 1 year to 1000 years. It aims at a
common representation of forest, cropland, temperate and tropical sites.- the generic
modeling approach, by using several of the first international models, will help
asserting the outputs of DynaMOS at the international level.
DynaMOS is original in the sense that the chemical composition of soil organic matter
is typically a dynamic variable but has not yet been subject to quantitative dynamic representation or simulation modeling in accordance.
