### How CO$_2$ warming effect stays overnight?

CO$_2$ doesn't significantly interact with solar radiation or UV, and doesn't store any significant amount of heat. What CO$_2$ effectively does is scattering infrared radiation emitted by the Earth, ...

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

Yes. Evapotranspiration ($ET$) can be calculated from latent heat ($LE$) by dividing by latent heat of vaporization ($\lambda$) $$ET = \frac{LE}{\lambda}$$ This assumes density of water equal to ...

### Sensible and Latent Heat. how to separate them

First some definitions: Latent heat is the heat that leaves or enters a system during a process where the temperature of the system stays constant. Phase changes are prime examples where latent heat ...

### Why are solar longwave and terrestrial shortwave radiations neglected in radiation balance models?

It is because longwave (LW) correspond to a negligible part of the solar radiation and shortwave corresponds to a negligible part of solar radiation. You can make an experiment yourself using NASA's ...

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

I'm not sure how accurate you need, but beginning NASA's global 398.2 watts per square meter estimate from their energy budget a rounding down based on temperature variation should give a pretty good ...

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

Answers will be different because they must be tied to a model of solar evolution, and all models are a bit different. So to answer your question we have to select a model. A pretty standard and ...

### How can sublimation of glacial ice cause positive mass balance?

Strictly speaking sublimation is the phase change from solid to gas without an intermediate liquid phase. So the way the term sublimation has been used in the text is partly wrong. Ice and snow on a ...

### How CO$_2$ warming effect stays overnight?

The greenhouse effect is a process that occurs when gases in Earth's atmosphere trap the Sun's heat. This process makes Earth much warmer than it would be without an atmosphere. The greenhouse effect ...

### Sensible and Latent Heat. how to separate them

Sometimes in meteorology, at least here in the US, we actually call thunderstorms convection, which can confuse the terminology a bit. There is moist convection (e.g., storms) and dry convection (e.g....

### Why are solar longwave and terrestrial shortwave radiations neglected in radiation balance models?

It is important to keep in mind the black-body approximated radiation for the Earth and the Sun. Notice how small the long-wave energy radiation is from the sun and how Earth's radiation peaks there. ...

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

A very simple answer is that it is related to the demands of the vegetation types and their ability to maximize the net radiation. A "perfect" plant that covered the entire surface would theoretically ...

### Can Horizontal Radiation Fluxes Contribute to Net Column Heating?

Yes, there are horizontal radiation fluxes. These can change the heating rate by 10-40 K hr$^{-1}$. They also change depending on the extent of the atmosphere you may be considering. One can also ...

### Direct and Diffused component of shortwave radiation in ERA5 data

This paper By Fiddes & Gruber (TopoSCALE: downscaling gridded climate data in complex terrain) provides a method to partition direct and diffuse from ERA-Interim. The results could easily be ...
