**Virtual Wx. Station uses the formula Cloud Base(Ft)=250(Temp. - Dew Pt.) to estimate the height.
The Height that air contains a perceptible quantity of cloud particles to become visible.
This will be calculated even if conditions do NOT permit cloud formation. +The unit for solar radiation is Watts per Square Meter |
