Giancarlo,

Have you tried with -mi-? It is a structured suite of commands to deal with multiple-imputation available with Stata 11 (-impute- is a simple, limited and old version of the command)

Anyway, I need some details before trying to code a solution for your problem. For instance, how many variables with missing values in each station? how many obs completely missing? Have all datasets the same missing pattern?

Federico
