ToBeReviewed/CALCULS/

hdyn.pro

Calculate the height by rapport to a reference state for a depth reference. See keywords for different possibilities. By default, the state reference is rho=1020 and the depth reference is gdepw[ka] with ka the first W level directly above 1000 m.

tophdyn Calculation

result = hdyn(tabsn, tabtn, TREF=TREF, SREF=SREF, PROFREF=PROFREF, LEVEL=LEVEL, GILL=GILL, SURFACE_LEVEL=SURFACE_LEVEL)

Return value

An array of the same size of sn and tn representing the dynamic height calculated from a reference depth nd by rapport to a reference state.

Parameters

tabsn        in required

array representing the salinity

tabtn        in required

array representing the temperature.Has the same size than SN

Keywords

TREF       

Give a value to this keyword to change the reference temperature used in the calculation when GILL is activated.

SREF       

Give a value to this keyword to change the reference salinity used in the calculation when GILL is activated.

PROFREF       

Give a depth to this keyword which will be considered as the reference depth (in this case, LEVEL has not any effect). the calculation will be effectuated until this depth effecting an interpolation between the the last W level above PROFREF and PROFREF.

LEVEL       

It is the same reference level to take. This level is defined like that gdepw[level] is the reference depth

GILL       

We activate this key if we want to calculate the dynamic height like in the GILL page 215, which means by rapport to a reference state which vary in depth and which is determined by a reference temperature tref at 0°C and a reference salinity sref at 35psu

SURFACE_LEVEL        default: 0

It is the level where we wan to calculate the dynamic height.

Known issues

Restrictions

Points for which we can not calculate the dynamic height (whose the batymetry is less deep than the reference depth) are put at the value !values.f_nan approximation: The pressure in decibars is equal to the depth in meters (the pressure increase of 1bar all 10m)
