Launched seven years earlier, The Global Atmospheric Research Program carried out its landmark GARP Atlantic Tropical Experiment after years of planning, orchestrated largely by UCAR, among participants worldwide. GATE established UCAR as an organizer of large initiatives involving the global community of atmospheric and related sciences. In 1978-79, the first GARP Global Experiment (depicted here) studied the global atmosperhic circulation and related weather systems.

A record-setting glider pilot, Joachim Kuettner used these aircraft as atmospheric sensing tools for decades. Here he is shown piloting a research glider in the 1950s. Kuettner (1909-2011) was a German-American scientist who worked in the U.S. space program, including the Mercury Redstone and Apollo projects. Later Kuettner coordinated and planned international atmospheric field studies, among them the landmark Global Atmospheric Research Program's Atlantic Tropical Experiment (GATE). In 1994 he joined the University Corporation for Atmospheric Research when the National Science Foundation awarded him the UCAR Distinguished Chair for Atmospheric Science and International Research. An active investigator into his 90s, Kuettner took part in the California-based T-REX field project in 2006. Shortly before his death in 2011, the Federal Republic of Germany presented Kuettner with the Officer's Cross of the Order of Merit, one of Germany's highest civilian honors.
