Abstract:

A simplistic manual method has been developed for determining the atmospheric stability based on FSCAT, a computer code that calculates the fractional stability category. The FSCAT algorithm retains the simplicity of the well-known Pasquill stability category scheme, and it also allows a much finer semicontinuous resolution of the stability of the surface boundary layer. The manual method allows the user to obtain the same results as with FSCAT, using cloud, wind, and solar angle data with a decision tree method, to determine the insolation class number, the net radiation index, and the fractional stability category. This practical method can be a useful tool for field operations where use of computers may not be possible.
