I am trying to generate spatially downscaled (5-10 arcminutes) future climate maps indicating *monthly* mean min and max temp, and precip.  Most people usually need to extrapolate monthly data into daily data (using for eg. [MarkSim][1]).  I just need the monthly.  There are various ways to do this using GCM data available on the internet, but I would like to try doing it using .cli files available from the [DSSAT crop modeling program][2]. I don't know how to get access to these files though.  

Do I have to install DSSAT to get the files?
