FULL-POS users guide since cycle 46, updated 8 Oct. 2021

Patricia — 2021-02-05T08:32:25Z

FullPos is a powerful and sophisticated post-processing package. It is intended to be used for operation and research as well. FullPos can perform vertical interpolations, horizontal interpolations and spectral filtering.
This manual, published in January 2021 and updated on 8 October 2021, contains information about the installation, the use and the management of the code of FullPos . Much of the information presented in this document is in principle available inside the code via the (…)

General Fortran optimizations guide, Dec 2019

Patricia — 2020-08-19T09:11:58Z

This document from Ryad El Khatib is the support of a training course of Fortran High Performance omputing for scientists and developers. The purpose of this course is to let developers be aware of the performance traps when they code a piece of scientific software in Fortran.
The expectation is that the developers will be able to write fairly-well-performing code at once, without the need of a computer specialist to recode and optimize the software sometimes later to ease the handover to (…)

EPYGRAM tool (February 2020)

Patricia — 2020-02-10T15:19:00Z

The epygram library package is a set of Python classes and functions designed to handle meteorological fields in Python, as well as interfacing their storage in various usual (or not) data formats.
The purpose of the library is to provide user-friendly interfaces to formats of data resources as FA, LFI, LFA (Meteo-France historical formats), GRIB/1-2 (...) and handy classes for manipulating meteorological fields, whatever their geometry is.
Therefore, it has been conceived basically for (…)

Turbulence diagnostic (Eddy Dissipation Rate), ARPEGE cy43, January 2020

Patricia — 2020-01-10T10:47:46Z

A new global turbulence forecast product for aeronautics
Aeronautical turbulence is a major risk for this sector with dozen of millions of dollars for companies, and more than 7000 hours of sick leaves. Turbulence suffered by planes has multiple sources such as CAT (Clear Air Turbulence) which is particularly dangerous because non detectable. MÃ©tÃ©o-France has developed a new diagnostic of turbulence through a common project between DSM/AERO and DR/CNRM. This new diagnostic is a (…)

Eradication of arrays bounds violations in IFS/ARPEGE/AROME, August 2019

Patricia — 2019-09-26T17:16:09Z

In this note, Ryad explains the origins of the arrays bounds violations issue and proposes a solution to eradicate them. This solution has been implemented in the code (CY47T0).

Cycling in the IFS-ARPEGE-AROME code: a GIT view, April 2019

Patricia — 2019-04-17T07:55:15Z

The diagram prepared by Alexandre Mary illustrates the evolution of cycles in the common code IFS-ARPEGE-AROME in the GIT repository of Meteo-France.
Main features to remember: all the main cycles (e.g. CY43T2, CY46) are tags on the master branch. a T cycle (e.g. CY47T1) is constructed as a merge of several individual branches, having the same starting point, usually a common cycle. the construction of a T cycle is processed in one go; then some so-called phasing corrections are brought in (…)

Meteo-France's GIT toolbox: GIT-tools

Patricia — 2016-09-07T08:00:00Z

GIT-GCP toolbox for Toulouse SRC, Feb. 2013
This document by Claude Fischer introduces the GIT toolbox, developed at Meteo-France (MF) and used since CY39T1/CY40 as Source Code Repository (SCR) in Toulouse. Therefore, these GIT-tools also become a reference device for Aladin and Hirlam partners committing code to MF's based common libraries.
The note is a shortened translation of the comprehensive GIT-tools documentation written by S. Martinez (COMPAS/GCO of MF). The latter in French, (…)
