For the data assimilation scheme, the supervised NN, the multilayer perceptrons (MLPs) networks are applied. The ADAO module provides data assimilation and optimization features in Python or SALOME context (see http://www.salome-platform.org/). Data assimilation “extracts the signal from noisy observations (filtering), interpolates in space and time (interpolation) and finally reconstructs state variables that are not sampled by the observation network (completion).“ The WRFDA system is in the public domain and is freely available for community use. Hence, data-assimilation with OpenDA can be as efficient as with custom-made implementations of data-assimilation methods. MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations.
