New constraints on shergottite petrogenesis from analysis of Pb isotopic compositional space: Implications for mantle heterogeneity and crustal assimilation on Mars
shergottite Pb isotopes Martian geochemistry crustal assimilation mantle heterogeneity
2017/4/10
Geochemical studies of shergottites (Martian basalts) based on Rb-Sr, Sm-Nd, and Lu-Hf isotopic systematics have
provided clues to understanding the geochemical evolution of the Martian mantle and id...
Data ingestion and assimilation in ionospheric models
Ionosphere models data assimilation data ingestion
2015/8/28
Current understanding of the ionospheric behaviour has been obtained through different observations, modelling and theoretical studies. Knowledge of the ionospheric electron density distribution and i...
A Forecasting Procedure for Plate Boundary Earthquakes Based on Sequential Data Assimilation
Plate Boundary Earthquakes Sequential Data Assimilation
2015/7/17
A forecasting procedure is proposed for plate boundary earthquakes in subduction zones. It is based on spatio-temporal variation in slip velocity on the plate interface, which causes interplate earthq...
A mechanistic modelling and data assimilation approach to estimate the carbon/chlorophyll and carbon/nitrogen ratios in a coupled hydrodynamical-biological model
mechanistic modelling data assimilation approach carbon/chlorophyll and carbon/nitrogen ratios
2009/11/11
The principal objective of hydrodynamical-biological models is to provide estimates of the main carbon fluxes such as total and export oceanic production. These models are nitrogen based, that is to s...
We use a four-dimensional variational data assimilation (4D-VAR) algorithm to observe the growth of 2-D plumes from a point heat source. In order to test the predictability of the 4D-VAR technique for...
Developing a dynamically based assimilation method for targeted and standard observations
dynamically based assimilation method targeted and standard observations
2009/11/9
In a recent study, a new method for assimilating observations has been proposed and applied to a small size nonlinear model. The assimilation is obtained by confining the analysis increment in the uns...
Synchronicity in predictive modelling:a new view of data assimilation
Synchronicity in predictive modelling new view data assimilation
2009/11/9
The problem of data assimilation can be viewed as one of synchronizing two dynamical systems, one representing "truth" and the other representing "model", with a unidirectional flow of information bet...
Data assimilation in a sparsely observed one-dimensional modeled MHD system
Data assimilation observed one-dimensional modeled MHD system
2009/11/2
A one dimensional non-linear magneto-hydrodynamic (MHD) system has been introduced to test a sequential optimal interpolation assimilation technique that uses a Monte-Carlo method to calculate the for...
A case for variational geomagnetic data assimilation:insights from a one-dimensional,nonlinear,and sparsely observed MHD system
geomagnetic data assimilation one-dimensional nonlinear observed MHD system
2009/11/2
Secular variations of the geomagnetic field have been measured with a continuously improving accuracy during the last few hundred years, culminating nowadays with satellite data. It is however well kn...
