The last one can have severe impacts for Australia, in particular, as the Australian great artesian basin is an excellent transient trap for excess precipitation which can then depress ocean levels temporarily

I wanted to get a volume for the mass of water landing on Australia duing a peak La Nina. I'd had a go a getting Australian precipitation data from the Australian Met. Office but I could only find data on an individual station basis which seems to be behind a UI and I didn't have the fu to guess how to ftp them.
