The Atlantic Stratocumulus Transition Experiment (ASTEX) was conducted in the vicinity of the Azores and Madeira Islands in the northeastern Atlantic from 1 to 28 June 1992. The goal of ASTEX was to study the type and amount of marine stratocumulus clouds and determine how these clouds are regulated. ASTEX combined coordinated satellite, airborne, island, ship, and buoy observations with modeling activities to investigate the consequences to the atmosphere and ocean of marine stratocumulus clouds and their life-cycle variations, including the important broken cloud regimes (ASTEX Operations Plan, 1992). ASTEX was part of the First ISCCP Regional Experiment (FIRE). The German research vessel Valdivia participated in that effort and performed atmospheric and oceanographic measurements including 156 radiosonde ascents.
