WebTerra and Atmospheric Composition Terra is the first satellite to provide integrated measurements of the processes connecting the atmosphere to emissions from activity on the ground. For example, Terra instruments measure both fires and smoke. In particular, Terra instruments measure aerosols (particles in the atmosphere) and carbon monoxide. Web8.4.1 Earth’s atmosphere. Ideas about atmospheric composition and climate on the early Earth have evolved considerably since the early 1960s. It is generally agreed that the atmosphere contained little or no free oxygen initially and that oxygen concentrations increased markedly near 2.0 billion years ago.
