摘要

如果我们考虑一下构成地球科学的学科划分:海洋-大气、陆地-大气、水圈、冰冻圈和平流层-对流层，我们就会看到地球表面在理解能量、水和物质的储量和通量方面的重要性。然而，对陆地表面特征的理解落后于我们对大气化学和空气污染对健康影响的理解。这就提出了一个哲学问题:“如果我们不能在时间和空间尺度范围内准确地了解陆地表面，我们对地球系统的理解又有多大信心呢?”

On the importance of considering land surface reflectance in earth system studies

If we consider the disciplinary divisions which make up earth science: ocean-atmosphere, land-atmosphere, hydrosphere, cryosphere, and stratosphere-troposphere, we can see the acknowledgement of the importance of the surface of the earth in understanding the stocks and fluxes of energy, water and matter. Yet understanding the features of the land surface lag behind our understanding of atmospheric chemistry and the health impacts of air pollution. This raises a philosophical question: ‘if we are unable to understand the land surface accurately over a range of temporal and spatial scales, how confident can we be in our understanding of the earth system?’.

期刊介绍： Clean Air Journal is the official publication of the National Association for Clean Air, a not-for-profit organisation. Clean Air Journal is a peer-reviewed journal for those interested in air quality, air quality management, and the impacts of air pollution relevant to Africa. The focus of the journal includes, but is not limited to: Impacts of human activities and natural processes on ambient air quality Air quality and climate change linkages Air pollution mitigation technologies and applications Matters of public policy regarding air quality management Measurement and analysis of ambient and indoor air pollution Atmospheric modelling application and development Atmospheric emissions Other topics on atmospheric physics or chemistry with particular relevance to Africa The scope of the journal is broad, but the core theme of the journal is air quality in Africa.
