9	!>\BRIEF constantes_var module contains most constantes like pi, Earth radius, etc...
10	!! and all externalized parameters except pft-dependent constants.
11	!!
12	!!\n DESCRIPTION: This module contains most constantes and the externalized parameters of ORCHIDEE which
13	!! are not pft-dependent.\n
14	!! In this module, you can set the flag diag_qsat in order to detect the pixel where the
15	!! temperature is out of range (look qsatcalc and dev_qsatcalc in qsat_moisture.f90).\n
16	!! The Earth radius is approximated by the Equatorial radius.The Earth's equatorial radius a,
17	!! or semi-major axis, is the distance from its center to the equator and equals 6,378.1370 km.
18	!! The equatorial radius is often used to compare Earth with other planets.\n
19	!! The meridional mean is well approximated by the semicubic mean of the two axe yielding
20	!! 6367.4491 km or less accurately by the quadratic mean of the two axes about 6,367.454 km
21	!! or even just the mean of the two axes about 6,367.445 km.\n
22	!! This module is already USE in module constantes. Therefor no need to USE it seperatly except
23	!! if the subroutines in module constantes are not needed.\n
24	!!
