How much does the biosphere contribute to Earth's entropy production?

Papers like 1, 2, etc. and the work of Axel Kleidon (e.g. 3) suggest that the the biosphere increases the production of entropy of Earth but I'd like to know if we could quantify this in a simple way. ...

FLUXNET15 - how to convert latent heat flux to actual evapotranspiration?

Can we convert latent heat flux to actual evapotranspiration using simply this conversion rate: 2.45 MJ m-2 day-1 = 1 mm day-1 (Allen, 1998)?

Can Horizontal Radiation Fluxes Contribute to Net Column Heating?

I've noticed that in many papers it's common to assume the (daily or longer averaged) vertically integrated radiative heating can be expressed $F_z(\text{TOA})-F_z(\text{SURF})$, where $F_z$ is the ...

How much energy does Earth surface radiate at night per square meter?

I am finding lots of information about Earth's energy budget, about how objects emit infrared radiation based on heat, and lots of related things, but nothing helping me figure out how much energy is ...

Sensible and Latent Heat. how to separate them

I need help with latent and sensible heat. P.S: I have been through all Wikipedia and other pages that say phase change and temperature change. My Question is: if there is convection, it will take ...

What will be the temperature on Earth when Sun finishes its main sequence?

We know that presently Sun is 4.5 billion years into its main sequence. It has another 5 billion years before it enters the Red Giant phase. We also know that Sun's luminosity increases by 10% every ...

How CO$_2$ warming effect stays overnight?

Water vapor looses it energy at night (no sun, no UV) and this is deposited as dew. Change of state requires a massive energy change, in general. Is the greenhouse effect of CO$_2$ not lost when it ...

What is the relationship between net primary productivity and emergy?

Looking at the Earth system as a whole and considering ecological economics, net primary productivity and emergy are two concepts that strike me as fundamental and likely related. I'm not sure what ...

Is Bowen ratio an absolute indicator of land surface type based on the amount of heat transfer from the surface?

Bowen ratio (BR) is the ratio of sensible heat flux to latent heat flux, i.e., $$Q=Q_{s}/Q_{l}$$ where $Q_{s}$ is the sensible heat flux and $Q_{l}$ is the latent heat flux. It is an indicator of ...
