I'm looking for a graph of improvements in spatial resolution for any atmospheric model (such as the UK Met Office Unified Model or ECMWF IFS). Ideally it would include a range of historical model versions and perhaps forecasts for future model resolutions.

$\begingroup$ Do you mean global atmospheric models for numerical weather prediction? Or climate model configurations? Or limited area configurations? Deterministic or ensemble ensemble setups? $\endgroup$ – BHF Mar 22 '16 at 22:37

$\begingroup$ Any of those are fine, I just wanted a figure to illustrate the fact that model resolutions have, in general, been increasing over time. $\endgroup$ – hertzsprung Mar 24 '16 at 8:48

Europe is looking nicer and nicer every year (source):
This is a little bit out of date, since AR5 is already out - the dates for the first 4 IPCC reports were:
- IPCC First Assessment Report, 1990
- IPCC Second Assessment Report, 1995
- IPCC Third Assessment Report, 2001
- IPCC Fourth Assessment Report, 2007
- IPCC Fifth Assessment Report, 2014
And an updated image for AR5 looks like this (both of these are AR5 model resolutions) (source, p145):
And that same PDF has another representation of increasing complexity, where cylinder height indicates complexity (source, p144):

$\begingroup$ Superb figures, thank you. The fact that they show how small scale steeper slopes are also resolved at higher resolutions was also something that I wanted to illustrate. $\endgroup$ – hertzsprung Mar 24 '16 at 8:49
