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 (…)

IO IN THE CYCLE 46t1r1 OF ARPEGE/IFS: CALL-TREE ASPECTS.

Karim Yessad — 2019-02-12T00:00:00Z

Abstract:
This documentation gives an overview of the IO (file reading and writing) done in the most usual configurations. This is not a technical documentation about IO but rather a documentation describing entries to IO routines. It is not a comprehensive documentation for all configurations but sticks to the main configurations used for example in the MF operational suite. When locating file reading and writing in the code one has realized that this is not so easy to find where these IO (…)

ARPEGE/ALADIN/AROME IO : technical aspects (cycle 39t1, May 2013)

Patricia — 2013-05-23T11:25:03Z

This document by Philippe Marguinaud describes the IO subsystem of ARPEGE/ALADIN/AROME for cycle 39t1. Only historic data IO is covered here, with a few words on Fullpos IO.
Contents : Organization of the code Field descriptors IO buffers Extracting/loading fields MFIOOPTS Code cleaning Grid-point/spectral Traditional input/output Grid-point input Grid-point output Grid-point output alternatives Spectral fields input/output Extended traditional output One file per NSTROUT task A single (…)

FA API package (Mar 2010)

Patricia — 2010-03-30T12:08:41Z

The FA API is a higher level application programming interface providing an easy access to FA file format.
The fa_api is a wrapper library that integrates several IFS/Arpege auxiliary libraries (fa, lfi, eggx, etc.) and provides unified and easy to use interface for manipulating FA files. The fa_api is intended mainly as a standalone externalized library for operational and R&D applications.
The main features: encoding and decoding of FA records (with automatic transforms from (…)
