ARPEGE Analysis Fields Selection
ARPEGE is a variable resolution spectral primitive
equation system. At the time of the experiment, it
was be running with semi-Lagrangian semi-implicit
scheme. The resolution is T149, 27 levels with
stretching 3.5. Time step: about 600 s. The
averaged resolution over the Atlantic is (roughly)
equivalent to T300, T400 and more over western
This data set will be the outcome of the data
assimilation suite run by Meteo-France in Toulouse.
Spatial coverage and resolution:
Global grid, latitude X longitude, resolution
1.5 degrees, poles excluded.
Each horizontal field for a given variable, at a
given time and a given level (whenever that
applies) will be stored as a GRIB message.
