I am quite sure that there are methods to estimate an optimal station-setup (probably colleagues with more experience will answer), but I want to point out an other thing: rainfall is mostly not uniform distributed. The topography has a major impact, also differences of the land cover can result in differences of the (micro - meso scale) climate. There are probably also coastal effects. I think, that it would be necessary to take this also into account. Which makes the calculation of number and place of the new stations more difficult. Hope this helps a little bit, cheers Wolfram
