ABLE-2B: Amazon Boundary Layer Experiment - 2B


Four PAMII stations were located near Manaus, Brazil during April through May, 1987, in support of NASA's ABLE-IIB experiment. The purpose of the ABLE experiment was the study of convective transport of trace gases (surface, and cloud mass transports) and the heat and water vapor budget within the Amazonian Basin during the rainy season. This experiment was one of several field projects involved in NASA's larger Tropospheric Chemistry Program. The PAM stations were adapted for mounting on top of 45-meter Rohn towers in order to locate the sensors above the dense tropical forrest canopy. They provided basic meteorological data, in one-minute averages, to augment other sensing systems such as tethered balloons, rawinsondes, GMDs, aircraft, and a host of atmospheric chemistry equipment. Data telemetered to Boulder, Colorado were accessed by scientists in Manaus using NCAR analysis software and relayed as real-time interactive displays to Manaus by a NASA communications link.
