Hi @step-671, I can forward this to colleagues, but I am afraid that we would need more radar worldwide to implement this in the future. I appreciate your understanding.
Satellite images are not in certain altitude. They are images from 36.000 km.
WV sat. images show the real time structure of WV in the atmosphere. They're not forecast products.
Windytv depicts forecast fields of clouds, rain, wind, rel. hum etc
