Note2:
Map(s) of riverflow direction is very important.
Currently, 1deg x 1deg version (Oki and Sud, 1996) and
0.5deg x 0.5deg version (Okada, 1999) are available.
The map should be placed/linked as fort.93
Note3:
io_ and jo_ in paramodel.h are used as io2_ and jo2_.
t126 (io_=360,jo_=181) and t248 (io_=720,jo_=361) are
usable in default, but other resolution io2_ and jo2_
needs to be selected manually. => in comfriv.h and g...
Grid coordination (1deg) is centered, such as
