### How to run earth system, land surface and climate models?

As alluded to in some of the comments, all of the CMIP5 models will have been run on supercomputers, and it takes a lot of effort to get one of them running on a new platform, even for a team who know ...

### Half of Earth with most landmass

You would have to cut somewhere along this circle: The only landmass here is New Zealand, eastern Australia, eastern PNG, western North America and some Pacific islands. I'm pretty sure you can tweak ...

### How to run earth system, land surface and climate models?

We are moving all of CESM to open source - in particular here is the latest version of the Community Terrestrial Systems Model (CTSM) https://github.com/ESCOMP/ctsm Formerly known as CLM, CTSM ...

### How to run earth system, land surface and climate models?

You can take a look at the Predictive Ecosystem Analyzer (PEcAn) - it is a statistical framework and workflow system that supports parameterization and analysis of a number of land surface, crop, and ...

### Can we define "drainage density" for a soil column (point-scale)?

Fundamentally it doesn't make sense to describe the point scale model with hillslope length and drainage density. If you are looking to model a soil column, you could use Darcy's law or Richard's ...

### Half of Earth with most landmass

It's a moot point, and probably varies somewhat according to the state of the tide. Visually, however, the 'pole of maximum ocean' is about half-way between two atolls in the south Pacific: Tautua, 9&...

### Map of earth subsurface temperature

At a depth of about 1200 km, the temperature can be assumed to be constant, about 5,200° Celsius (9,392° Fahrenheit). At depths between few hundred meters and some kilometers, the temperature is ...

### Pertinence for a formulae similar of the RMSE to measure the meteorologic forcing impact on the variability on a model output

I think you might be getting terms mixed up. Let's follow the standard convention of data assimilation and call your model output from the ($k^{\text{th}}$ parameterization/forcing) $X_k$ and the ...

### How to calculate the specific humidity based on the saturated specific humidity?

Just in case it will save a great deal of time for others in the future, ill recommend the metpy package. https://unidata.github.io/MetPy/latest/api/generated/metpy.calc....

### How to calculate the specific humidity based on the saturated specific humidity?

The answer is easy. Replace $T$ with $T_d$, where $T_d$ is the dewpoint temperature. I will say I am not all that familiar with those equations, but that is besides the point.

### High resolution global land use projections

While this isn't 10km or less, the CMIP6 dataset is released as of last week. It's now at 0.25degree spatial resolution which is an improvement.
