Roadmap to v1.0

[AlexisRenchon]

• [x] Global simulations: stable & fast #732, #675
• [x] Calibration: framework in place #621
• [ ] Documentation: quality & comprehensive #745
• [x] Snow model #629

Issues I think we can close before the release Documentation:

• [ ] #681 - @AlexisRenchon - documentation (check if this closes issue #499?)
• [ ] #240 - All - documentation or close if duplicate
• [ ] #296 - @kmdeck - documentation

Scientific improvements:

• [ ] #657 - ? - easy fix for scientific improvement
• [ ] #655 - ? - easy fix for scientific improvement
• [ ] #645 - @kmdeck - easy fix for scientific improvement
• [x] #671 - @kmdeck - required, also closes #594
• [ ] #630 - @kmdeck - snow model integrated with soil/canopy - see also #146
• [ ] #597 - @kmdeck - required

Refactoring:

• [x] #326
• [ ] #674 -@kmdeck - refactoring to make code design better
• [x] #594 - @kmdeck - can be taken care of in 671
• [ ] #611 - @Sbozzolo - easy fix for consistency
• [ ] #600 - @AlexisRenchon and @kmdeck - nice feature and clarifies where LAI/SAI/RAI are stored
• [ ] #250 - @kmdeck - nice to have
• [ ] #580 - @Sbozzolo - good to have
• [ ] #316 - easy fix
• [x] #615 - easy fix

Implicit stepping

• [x] #663 - @kmdeck - implicit tendency for energy hydrology . See also issue #135
• [x] #660 - @kmdeck
• [ ] #661 @kmdeck

Global runs:

• [ ] #644 - All - Global run on GPU
• [ ] #608 - All - plots for experiments in the paper
• [ ] #596 - All - required
• [ ] #398 - All (closing issues above should close this)
• [x] #583 - @AlexisRenchon - required
• [ ] #687
• [ ] Figure out NaNs - (a) if we make ac_canopy larger, fewer NaNs. (b) if we make the thermal timescale for phase change longer, we get fewer NaNs (c) if we make the timestep smaller, we get fewer NaNs -> issue with timestepping? better implicit solver? One other question: why NaNs, and not domain errors?
• [ ] Improve/debug diagnostics - more variables, perhaps we want monthly averages
• [ ] Make better plots, maybe animations
• [ ] Use mask in diagnostics so we only get continents
• [ ] Use units that are reasonable for the community

#593 and #586 duplicates?
