Cloud Seeding Southeast of Mexico City, 1974-96

Jorge Estrada Betancourt, Isabel Villasenor Diaz


Silver iodide was emitted from ten burners from 09 to 13 CST on about half the days, randomly selected before the start of the five-month rainy season, June-October, south and southeast of Mexico City in 1974, 1975 and 1976. Five burners were of voltiac arc type, operating at approximately 2500 C; the other five used butane gas, burning at about 1,000 C. Neither type was calibrated, so no infor- mation is available on their output of freezing nuclei. On each seeded day, an average of seven burners operated, consuming 0.24 kg of Agl per day.
