将不同卫星的测量结果结合成三维网格的时间序列（从而显示从几小时到几年的大气化学演变）。通过这种方式，科学家还可以根据对大气中发生的化学反应的了解，对无法直接测量的化学物质做出推断。数据同化还可用于向卫星科学家提供那些可能最需要测量的物种的指示。三维网格分析的时间序列也可以帮助科学家提高他们对大气化学的理解，这是这种分析的最终目标，就像气象学家在近几十年来通过对对流层和平流层精确天气分析的研究，了解了很多关于大气动力学过程的知识一样。本文的第三部分将描述2002年2月发射的ESA卫星Envisat为大气科学家和建模人员提供的新的可能性。
combine measurements from different satellites into time-series on three-dimensional grids (thereby showing the evolution of atmospheric chemistry over periods from a few hours to years). In this way scientists can also make inferences about chemical species that are not directly measured, based upon knowledge of the chemical reactions occurring in the atmosphere. Data assimilation can also be used to give an indication to the satellite scientist of those species that might be the most important to measure. The time-series of three-dimensional gridded analyses can also help scientists to improve their understanding of atmospheric chemistry ± this is the ultimate goal of such analyses ± in much the same way as meteorologists have learnt a lot about dynamical processes of the atmosphere from the study of accurate tropospheric and stratospheric synoptic analyses over recent decades. Part 3 of this article will describe the new possibilities for atmospheric scientists and modellers offered by Envisat, the ESA satellite launched in February 2002.
