Atmospheric inverse modeling with known physical bounds: an example from trace gas emissions
Atmospheric inverse modeling physical bounds
2014/12/18
Many inverse problems in the atmospheric sciences involve parameters with known physical constraintsExamples include nonnegativity (e.g., emissions of some urban air pollutants) or upward limits impli...
Improving computational efficiency in large linear inverse problems: an example from carbon dioxide flux estimation
computational efficiency large linear inverse problems carbon dioxide flux estimation
2014/12/12
Addressing a variety of questions within Earth science disciplines entails the inference of the spatiotemporal distribution of parameters of interest based on observations of related quantities. Such ...
Reformulation of the Vening-Meinesz Moritz Inverse Problem of Isostasy for Isostatic Gravity Disturbances
Crust Gravity Isostasy Moho Interface Spherical Harmonics
2013/3/11
The isostatic gravity anomalies have been traditionally used to solve the inverse problems of isostasy. Since gravity measurements are nowadays carried out together with GPS positioning, the utilizati...
Estimating basal properties of ice streams from surface measurements:a non-linear Bayesian inverse approach applied to synthetic data
basal properties ice streams surface measurements non-linear Bayesian inverse approach
2010/2/4
We propose a new approach to indirectly estimate basal properties of ice streams, i.e. bedrock topography and basal slipperiness, from observations of surface topography and surface velocities. We dem...
Influences of observation errors in eddy flux data on inverse model parameter estimation
observation errors eddy flux data inverse model parameter estimation
2010/1/18
Eddy covariance data are increasingly used to estimate parameters of ecosystem models. For proper maximum likelihood parameter estimates the error structure in the observed data has to be fully charac...
Mapping monthly rainfall data in Galicia (NW Spain) using inverse distances and geostatistical methods
monthly rainfall data Galicia inverse distances geostatistical methods
2010/1/26
In this paper, results from three different interpolation techniques based on Geostatistics (ordinary kriging, kriging with external drift and conditional simulation) and one deterministic method (inv...
Radar rainfall estimates in an alpine environment using inverse hydrological modelling
Radar rainfall an alpine environment inverse hydrological modelling
2010/1/26
The quality of hydrological modelling is limited due to the restricted availability of high resolution temporal and spatial input data such as temperature, global radiation, and precipitation. Radar-b...
