ARPEGE-TROPIQUES analysis from Meteo-France are available over an Atlantic Africa area  for all the AMMA scientific community. ARPEGE is the acronym of "Action de Recherche Petite Echelle Grande Echelle". This model is used both by Meteo-France and ECMWF; at ECMWF is is named IFS (Integrated Forecasting system). ARPEGE is a global spectral model, with a gaussian grid for the grid-point calculations. ARPEGE is used operationnaly at Meteo-France ( two versions, ARPEGE-FRANCE with a stretched coordinate and ARPEGE-TROPIQUES with a regular resolution). ARPEGE-TROPIQUES differs mainly from ARPEGE by ist regular grid of 50 km and a longer cut-off (3hr) enabling the assimilation of more data than ARPEGE.

Operational analysis produced by ARPEGE-TROPIQUES have been extracted  on regular latitude/longitude grid and converted from GRIB (meteorological format) to Netcdf (self-describing format, widely used in modelers community).
