Data Merging for Creating Long-Term Coherent Multisensor Total Ozone Record
Published in Ni-Bin Chang, Kaixu Bai, Multisensor Data Fusion and Machine Learning for Environmental Remote Sensing, 2018
In Earth system science, ozone in the atmosphere can be routinely divided into two typical groups simply by considering their locations residing in the atmosphere. Specifically, these groups are: stratospheric ozone residing in the upper atmosphere (i.e., stratosphere) and tropospheric ozone residing in the lower atmosphere (troposphere) (Figure 15.1). As the second major layer of the Earth's atmosphere, the stratosphere resides above the troposphere while being below the mesosphere, with a varying vertical height at different latitudes. Investigations indicate that the tropospheric ozone poses adverse impacts on living beings on Earth by affecting human health, natural vegetation growth, crop yield, and so on, whereas the stratospheric ozone enables to protect life on Earth by absorbing the harmful ultraviolet (UV) radiation from the Sun. When stratospheric ozone absorbs high frequency radiation, such as the UV light, it often involves a photochemical reaction process, which affects and modifies the background chemistry and energy budget of the stratosphere, in turn resulting in variations of atmospheric dynamics (McPeters et al., 2013).

In higher education, climate topics are often taught under the umbrella of atmospheric and Earth system sciences. However, it is not clear what climate change expertise mean and if necessary competencies are taught in the education of atmospheric and Earth system sciences. Here, we use atmospheric and Earth system science as a combination of atmospheric sciences, defined as study of structure and evolution of, and phenomena within planetary atmospheres (Wallace and Hobbs, 2006), and Earth system science, which focuses on interactions and feedbacks within the geospheres of the Earth (Jacobson et al., 2000).
