The Global Atmospheric Research Programme was a fifteen year international research programme led by the World Meteorological Organization and the International Council of Scientific Unions. It began in 1967 and organised several important field experiments including GARP Atlantic Tropical Experiment in 1974 and the Alpine Experiment (ALPEX) in 1982. Its field experiments helped make significant progress in meterorology in particular allowing major improvements in Numerical Weather Prediction.
