calfis.F @ 3406

Last change on this file since 3406 was 1225, checked in by lguez, 15 years ago

Added some "intent" attributes in declarations.

In "phyredem", "dtime" is not declared. It is not in any included
file. Probably accepted by compilers as an intrinsic non-standard
function. Removed this element of "tab_cntrl".

Added some "only" clauses in "use" statements.

If the ozone field is read from a file, it is now updated every
360th of the length of the current year, regardless of that length.

In "physiq", "omega" was output before it was defined. Moved the
output instruction after the definition.

42	c remarques:
43	c ----------
44	c
45	c - les vents sont donnes dans la physique par leurs composantes
46	c naturelles.
47	c - la variable thermodynamique de la physique est une variable
48	c intensive : T
49	c pour la dynamique on prend T * ( preff / p(l) ) **kappa
50	c - les deux seules variables dependant de la geometrie necessaires
51	c pour la physique sont la latitude pour le rayonnement et
52	c l'aire de la maille quand on veut integrer une grandeur
53	c horizontalement.
54	c - les points de la physique sont les points scalaires de la
55	c la dynamique; numerotation:
56	c 1 pour le pole nord
57	c (jjm-1)*iim pour l'interieur du domaine
