@reklawbl goood question.
Would love to see some water vapour imagery.
BLUE, VISIBLE, INFRA+, WATER VAPOUR (WV).

Some users ask for Total Precipitable Water. I have to say I don’t know which is the most useful.

TPW is a calculation of how much water vapour (specifically water vapour) is available to condense at a point within a column of air from the surface to the top of the atmosphere. This can give forecasters information on how much moisture is available in an area if a system or storm gains access to it.

WV is the "current" presence and movement of water vapour via satellite in the upper and mid-levels of the atmosphere. Which can help forecasters determine where the water vapour (or lack there of) is from and where it may be headed.

One is more of a forecast layer and the other is a satellite image. Both are useful and you can gain more information than what I've stated from each.

Anyone else please feel free to chime in or tell me I'm wrong - hope that helps!

Thank you that’s clear now !
