The physicist Edward Teller estimated that a constellation of satellites providing continuous atmospheric measurements over a one square kilometergrid worldwide, which is currently cost-prohibitive, would only improve long-range forecasts from the current five days to approximately 14 days.
Using a grid of 14-kilometer cells, the new system will be able to simulate from one to five years per day of computing time, up from the three months or so that Jaguar was able to churn through in a day.
