| Sumario: | During the last 35 years, the joint programme of the International Atomic Energy Agency and the World Meteorological Organization (WMO) devoted to the systematic measurement of oxygen-18, deuterium and tritium in precipitation on a global scale has compiled a database with more than 100 000 isotope measurements. The survey, known as the Global Network for Isotopes in Precipitation or GNIP, provides basic data on the spatial and temporal distribution of these isotopes. This has been recognized as the major reference of isotope data in precipitation for hydrological applications. For more than a decade, the oxygen-18 and deuterium records have also been used to validate atmospheric global circulation models and to calibrate isotope records in palaeoclimatic archives, especially in continental areas, such as ice cores, lake sediments, tree rings, speleothems and groundwater. The paper briefly reviews the main fields in the earth sciences that benefit from the GNIP database and describes the new requirements and challenges of the programme to create, reactivate or maintain some of the co-operating meteorological stations. |
