Variational data assimilation via sparse regularisation
This paper studies the role of sparse regularisation in a properly chosen basis for variational data assimilation (VDA) problems. Specifically, it focuses on data assimilation of noisy and down-sampled observations while the state variable of interest exhibits sparsity in the real or transform domains. We show that in the presence of sparsity, the ‘1-norm regularisation produces more accurate a...
متن کاملA review of operational methods of variational and ensemble-variational data assimilation: Ensemble-variational data assimilation
Variational and ensemble methods have been developed separately by various research and development groups and each brings its own benefits to data assimilation. In the last decade or so, various ways have been developed to combine these methods, especially with the aims of improving the background-error covariance matrices and of improving efficiency. The field has become confusing, even to ma...
متن کاملData Assimilation with sparse GPs
Inferring wind-fields from remote observations poses two issues that need to be tackled: the first one is to represent two-dimensional Gaussian fields, or processes (for each location we have random variables specifying the X-, and Y-directions. The second problem is the inference with the inherently non-tractable likelihood model, governed by the underlying physics governing the wave formation...
متن کاملSparse Multinomial Logistic Regression via Bayesian L1 Regularisation
Multinomial logistic regression provides the standard penalised maximumlikelihood solution to multi-class pattern recognition problems. More recently, the development of sparse multinomial logistic regression models has found application in text processing and microarray classification, where explicit identification of the most informative features is of value. In this paper, we propose a spars...
متن کاملMesoscale Variational Assimilation of Profiling Radiometer Data
Retrieved profiles of temperature, water vapor, and cloud liquid water are obtained through neural net inversions of the brightness temperatures, where the neural net is trained using radiosonde soundings and corresponding forward modeled brightness temperatures. An observation operator has also been developed for the direct assimilation of the measured brightness temperatures, using the forwar...
