Clouds height control through simConnect

Hello,

In FSX, I'm setting weather using simConnect. Weather is given to FSX through METAR messages and "SimConnect_weatherSetObservation" function. In the METAR I can adjust some clouds parameters (type, base, type of top, precipitation, ...). However, I can't see the way to set the adjust the cloud height... Does somebody know how to do that ?

Tahnk you.

Paul
