10	!!
11	!!\n DESCRIPTION: This module contains subroutines for the interfacing between ORCHIDEE and LMDZ and between the driver
12	!! dim2_driver and the reste of ORCHIDEE. Follwoing subroutines exists:
13	!!
14	!! - intersurf_initialize_2d : Intitialization and call to sechiba_initialize, called from dim2_driver
15	!! before the first call to intersurf_main_2d.
16	!! - intersurf_main_2d : Main subroutine will call sechiba_main, called from dim2_driver at each time-step
17	!! - init_intersurf : Initialize grid information when coupling with LMDZ. This subroutine is called
18	!! from LMDZ before call to intersurf_initialize_gathered
19	!! - intersurf_initialize_gathered : Intitialization and call to sechiba_initialize, called from LMDZ
20	!! before the first call to intersurf_main_2d.
21	!! - intersurf_main_gathered : Main subroutine will call sechiba_main, called from LMDZ at each time-step
22	!! - intsurf_time : Initialize and update time information, called in the initialization phase
23	!! and at each time step from the different intersurf subroutines.
