Use of the 2D structure of GOM-arrays for the assimilation of
radar reflectivities in the AROME model at MÃ©tÃ©o-France by Eric Wattrelot : A 1D method to get relative humidity retrievals from
radar reflectivities : why and how ? Dataflow of the 2D-GOM and specific points linked to
A variational diagnostic analysis tool has been developed for diagnostic purposes. This tool will be the successor of "diagpack" for nowcasting issues.
It is inspired by the concept of diagnostic analysis which has been the central concept for the development of diagpack.
From the technical (...)
This report was published by Thibaut Montmerle, Claude Fisher and LoÃ¯k Berre on February 2005.
It presents the aim, strategy and first results for the implementation of an operational variational data assimilation systelm in the ALADIN/France model. Starting from the experience gathered over (...)
This note gives a detailed description of the algorithmic part, for the benefit of phasing, remote installations and development. A theoretical overview is recalled for completeness with the technical section. A "User’s guide" is added for the general users of 3dvar. Formalism of incremental (...)
