The physicist Edward Teller estimated that a constellation of satellites providing continuous atmospheric measurements over a one square kilometer grid worldwide, which is currently cost-prohibitive, would only improve long-range forecasts from the current five days to approximately 14 days.

In addition, since fire is a finer-grained and faster-moving phenomenon than weather, a finer grid is used for the fire model than for the atmospheric model each grid square is a few metres, rather than a few tens of metres, across.
