Microphysically unstable water droplets in cold fog can be modified by such methods as aircraft dropping small particles of dry ice into the fog or ground dispensers spraying iodide or venting liquefied propane into the fog.
Warm fog is very difficult to modify.
It has been my thought that the pursuit of single compounds severely limits the potential for the hygroscopic model. The following methodology is hereby published and becomes public domain worldwide. I have chosen this journal since I am the publisher and it has worldwide circulation, website publication, as well as being indexed on a number of electronic databases. By this publication individual patent and monopoly of the technology will be prevented. Machinery for dispensing and storage of the material will require some minor development.
