The problem isn’t the granularity of observations, it’s the granularity of the grid with which the simulations are run. As I understand it (by analogy with my own field of macroeconomics) the current limit is the fact that the grid is coarser than the average size of a cloud, and that therefore cloud cover needs to be approximated. That is the real source of uncertainty.
- bumby 7y agoInteresting. So is the grid limited due to computational complexity, like the mesh in finite element analysis?
- qubex 7y agoPrecisely. But don’t take my word for it. If you’re into a light introduction, consider watching Sabine Hossenfelder’s interview of Tim Palmer (a theoretical physicist’s interview of a leading climatologist is a thing of beauty in its own right).
- Angostura 7y ago> The problem isn’t the granularity of observations Perhaps you should tell the people who are running the "big observational campaign happening right now" that they can pack up and go home.
