Abstract:

ON 15 February 1961, the Institute of Applied Geophysics, Academy of Sciences USSR, undertook the clearing of the skies over the Crimean Astrophysical Observatory and the nearby town of Dzhankoy in preparation for a total eclipse of the sun, whose umbra would pass over these points. Preliminary investigations showed that heavy supercooled clouds driven by fast winds could be dissipated by spraying carbon dioxide very rapidly into individual cloud banks. The total seeding area is divided into unit areas roughly in the form of quandrangles, and each quadrangle is seeded in parallel lines with and against the wind. Seeding time may be reduced by increasing the carbon dioxide dosage and by seeding fewer lines at greater intervals. Author
