Hong,

     Without any real measurement (in-situ or remote) there really is NO
way anyone can "create" rainfall data on the ground. If you have
temperature and dew point data at "all levels" in the troposphere (say
10 levels) then you can approximate by computing the "precipitable
water", which is a better-than-nothing data for rainfall.  But, I would
suggest you go through the online precip data sources (such as NOAA) and
get the true precip data for your case.

    Good Luck!
