Abstract
Atmospheric occurrences that decrease visibility, particularly fog, smoke, smog and the like, are cleared at sites such as airports by an array of EGD spray units emitting submicron size charged water droplets to attach to airborne particulates and electrostatically precipitate those to ground. Independent variables of the array and the EGD jets from the spray units are controlled to control the dependent variables characterizing the space-charge cloud thus developed. The methods and apparatus control the height to which clearing of the airborne particulates occurs to improve visibility and the time required for such clearing. Specific compact spray units are self-contained, can be radio operated, and are movable. Placement of the units for removal of radiation and advection fog with respect to airport runways include a square array of the spray units proximate the runway for radiation fog control and upwind location of arrays for advection fog precipitation. Specific characteristics of small, medium and large spray units suitable for use in the arrays are set forth.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
