Hello

As I understand from your message that you have the data for the three stations
but the problem is that you don't have a complete set of data to the three
station except in only one station (I hope I am right). What I advise you to do
is to use the Time Series Analysis in this case especially the stochastic
modelling because this kind of models could detect the serial correlation
between the data and based on this serial correlation (auto regressive
correlation) it could predict the missing data in the data series. For the time
series analysis you have two options, either you use the parametric models (ARMA
and ARIMA models) or the non parametric models (The K-Nearest neighbourhood
model) it depends mainly on the normality assumption of the data. You can find
alot of references about these models at the net, just search with the key words
(ARMA, ARIMA, etc). I think this kind of modelling will be very helpfull to you.
If you have any question don't hazitate to contact me

Subject: [hydrologymodel] rainfall data problem

Hello to everybody in this forum,
I am a forester from Greece and i am doing my Msc in mountain
hydrology. I have a specific problem with my meteorological rainfall
data. I have only one station with all the data of rainfall and i want
to complete the data of 2 other stations for the same period without
loosing the max and min data. I would be thankful if anyone can tell
me some methods for this problem, or to send me some links for search.
