Comparison of the ensemble Kalman filter and 4D-Var assimilation methods using a stratospheric tracer transport model
the ensemble Kalman filter 4D-Var assimilation methods stratospheric tracer transport model
2014/12/19
An ensemble Kalman filter (EnKF) assimilation method is applied to the tracer transport using the same stratospheric transport model as in the four-dimensional variational (4D-Var) assimilation system...

Various mass fixer algorithms (MFAs) have been
implemented in the Integrated Forecasting System (IFS) of
the European Centre for Medium-Range Weather Forecasts
(ECMWF) to ensure mass conserva...
Downscale cascades in tracer transport test cases: an intercomparison of the dynamical cores in the Community Atmosphere Model CAM5
tracer transport test cases the dynamical cores Community Atmosphere Model CAM5
2014/12/10
The accurate modeling of cascades to unresolved scales is an important part of the tracer transport component of dynamical cores of weather and climate models. This paper aims to investigate the abili...
Mass-conserving tracer transport modelling on a reduced latitude-longitude grid with NIES-TM
Mass-conserving tracer transport modelling a reduced latitude-longitude grid NIES-TM
2014/12/9
The need to perform long-term simulations with reasonable accuracy has led to the development of mass-conservative and efficient numerical methods for solving the transport equation in forward and inv...
Spring molybdenum enrichment in scallop shells: a potential tracer of diatom productivity in temperate coastal environments (Brittany, NW France)
Spring molybdenum enrichment scallop shells diatom productivity temperate coastal environments
2010/1/21
Skeletal molybdenum/calcium ([Mo]/[Ca])shell ratios were examined in shells of the Great Scallop Pecten maximus collected in temperate coastal environments of Western Europe (42 to 49° N). These ratio...
Turbulence characteristics in grassland canopies and implications for tracer transport
Turbulence characteristics grassland canopies implications tracer transport
2010/1/20
In-canopy turbulence is a required input to study pollutant cycling and chemistry within plant canopies and to link concentrations and sources. Despite the importance of grasslands worldwide, most pre...
Nitrate retention and removal in Mediterranean streams bordered by contrasting land uses:a 15N tracer study
Nitrate retention removal Mediterranean streams contrasting land uses 15N tracer
2010/1/19
We used 15N-labelled nitrate (NO3−) additions to investigate pathways of nitrogen (N) cycling at the whole-reach scale in three stream reaches with adjacent forested, urban and agricultural land...
Quantifying biologically and physically induced flow and tracer dynamics in permeable sediments
biologically and physically induced flow tracer dynamics permeable sediments
2010/1/14
Insight in the biogeochemistry and ecology of sandy sediments crucially depends on a quantitative description of pore water flow and the associated transport of various solutes and particles. We show ...
