#2632 new Bug
new expression to compute air and surface potential temperatures in bulk formulae
| Reported by: | gsamson | Owned by: | gsamson |

| Priority: | low | Milestone: | |

| Severity: | minor | Keywords: | |

Description
Context & Analysis
The actual "gamma_moist" function used to convert air absolute temperature to potential temperature can be replaced by the "Exner" function, which takes into account air pressure variations and is commonly employed in atmospheric models, as well as the ABL model.
This potential temperature is used in the turbulent sensible heat flux calculation, as well as the atmospheric bulk Richardson number.
Fix
replace "gamma_moist" function by a "Exner" function in sbc_phy.F90 and introduce a new function to compute air pressure from other available atmospheric variables.
