Environmental isotope data no. 2: World survey of isotope concentration in precipitation (1964-1965)

This is the second volume of the publication 'Environmental Isotope Data: World Survey of Isotope Concentration in Precipitation'. The first volume, which was published in May 1969, included data from 1953-1963. This second volume is primarily concerned with the concentration of the environmental isotopes (tritium, deuterium and oxygen-18) in monthly samples of precipitation taken by a global network of 221 stations in the period 1964-1965. Selected meteorological data, such as amount of precipitation, vapour pressure and temperature are also presented. Data before 1963 which were not appropriate and available at the time of the first issue have also been included as late reports. The collection of the precipitation samples is carried out by the meteorological services of 65 countries and territories. Analyses of the network samples are done in co-operating laboratories in Canada, Denmark, India, Israel, New Zealand, Sweden and the United States of America and in the IAEA Laboratory in Vienna
