Lal, D

The possibility of using cosmic-ray-produced radioisotopes for- studying arge scale circulation in the atmosphere is explored. Radioisotopes are observed whose half lives are comparable to time scales involved in the atmospheric circulation. Four of the isotopes (S/sup 35/, Be/sup 7/, P/sup 33/, and P/sup 32/ have half life riods ranging from two weeks to three months, and one (Na/ sup 22/) has a half life of about two and a half years. Isotope production is continuous, constant, strongly dependent on the latitude and altitude in the atmosphere, and independent of meteorological fuctors. These isotopes can be used for investigating the nature of circulation of air in the troposphere and the detailed mechanism of exchange of air between the stratosphere and the troposphere. Experimental work on determination of the concentration of these isotopes in rain water is summarized. (auth)
