Interesting, is weather forecasting limited by computational resources 
and not data availability? So if an organization
had better resources with the same set of input data they could perform 
simulations that would be better at forcasting than a less well
endowed resource?, or is it quantity and quality of data?  Are there 
machines capable of simulating 1km cells, and is there data for these, 
presumably this data varies from region to region, with some areas 
having more sensor data than others?
