Description

Atmospheric ethylene (C_2H_4) levels were examined in a tropical rain forest situated at the equator, Amazonas Prefecture, Colombia, during 1982,During the rainy and dry seasons, the forest atmosphere showed scarcely vertical changes in C_2H_4 concentration for night and day determinations. The concentrations diurnally varied in the range of 1.1 to 1.9 and 0.9 to 1.3 ppb in the rainy and dry seasons, respectively. An air sampler was developed to collect atmosphere without contaminations due to pump and stopcock usage.
