Last change on this file since 3659 was 1764, checked in by Laurent Fairhead, 12 years ago

Inclusion d'une routine qui lit des champs d'aérosols stratosphériques
mensuels, prescrit des propriétés optiques et modifie le rayonnement en
conséquence. Pour le moment, seule l'interaction avec le rayonnement ondes
courtes est pris en compte. Les fichiers d'input doivent être au format des
fichiers de sortie. Contrôlé par la variable logique: flag_aerosol_strat
(false par défaut dans DefLists?/config.def)

Boucher

A new routine has been added to the code that reads in monthly stratospheric
aerosols, prescribes optical properties and modifies radiation accordingly.
Presently, only the interaction with short wave radiation is taken into account.
Input files must be formatted as are the aerosol output fields. Control is by
the logical flag: flag_aerosol_strat (which is false by default and included
DefLists?/config.def)
