[RegCNET] Echam5 projections and downscaling

[Dimos]

Dear RegCNET,

Quite a newbie in the RegCM3 and climatology in
general, I could definitely use some advice, links,
tutorials, if possible, at the below:

1)I plan to install RegCM3 on a single processor
Debian/GNU Linux i386 machine
2)Run simulations (serial mode) for ECHAM5 with A1B
emission scenario, for 40 years, daily or monthly for
a  region in Greece, 
3)Produce output in the finest resolution possible,
that is 50km for RegCM3 (right?)
4) Or, a nested simulation for a finer resolution grid
(say 20km)?
5)Finally, downscale, at 1km. Which is the approach
you may recommend for downscaling of RegCM3 grids down
to 1km? 

Many thanks :-)
