ABSTRACTSince 1978 the Instituto de Geocronología y Geología Isotópica (INGEIS) integrates the GlobalNetwork for Isotopes in Precipitation (GNIP) in cooperation with the International Atomic Energy Agency (IAEA) and the World Meteorological Organisation (WMO). In this framework, INGEIS established a National Collector Network for Isotopes in Precipitation (RNC) Since 1961, GNIP is devoted to the measurement for isotope contents in precipitation samples and was set up with the main objective of evaluating, on a global scale, the spatial and temporal distribution of isotope contents in precipitation and their dependence on relevant meteorological investigations, relating to water resources inventory,  planning and development. The operation of the network in Argentina began in November 1978, with one station located in Buenos Aires City. Then, after few years, this reached a maximum of 25 stations at different altitudes and latitudes, covering a wide range of temperatures.  This work present the evolution of the project along 20 years of operation
