Hello Hilmar,

We have published several datasets on individual 
precipitation events from which you can calculate 
a mean value. These data are from about 25 miles 
east of Syracuse NY, but may be of use 
nonetheless. Groundwater values are much closer 
to winter precipitaion values than the mean value 
(due to transpiration of summer precip.).The 
references are listed below, or you can go to the 
website at the bottom of this message and click 
on publications to download the PDFs.
I hope this helps,
Bill
