Reanalysis is the assimilation of long time series of observations with an unvarying assimilation system to produce data sets for a variety of applications; for example, climate, chemistry-transport, and process studies. Because the longest, most complete set of observations exists for the atmosphere, reanalyses have focused on atmospheric assimilation. As the satellite records of chemical, land and oceanic parameters lengthen in time, reanalyses will be of interest to these fields. In this chapter discussion will be drawn from the experience of atmospheric reanalysis, but the issues raised are relevant to all types of reanalysis.
