Abstract

There currently exists great interest in the study of certain atmospheric gases of long life which share the common property of absorbing infrared radiation. These gases, responsible for the greenhouse effect, are being eliminated into the atmosphere by anthropogenic activity in the processes connected to agriculture and also industrial processes. The group already has considerable experience in observations of ozone, and has specialized in recent years to be able also to measure CO2, N2O and CH4, the most important of the greenhouse effect gases. The intention of this work aims, in the first stage, to study and compare different behaviors in natural ecosystems and, at the same time, to gather sufficient data to be able to determine the tendency of annual growth of these gases.
