Presents a device for recording atmospheric carbon dioxide profiles. Operation of the system; Accuracy of the measurements; Typical calibration of the system.
The article presents a study regarding atmospheric environmental conditions of the rain forest in southern Nigeria. Carbon dioxide concentration in the tropical rain forest undergrowth and temperate woods was not observed to exceed 0-06% by volume. There are no significant differences between the concentrations in primary and secondary forests. Data from the thermohygrograph records of the temperature and humidity conditions in the tree tops and undergrowth are presented. Discussion regarding the possible effects of Nigeria's environmental conditions on the life of undergrowth plants is also presented.
