Several recent reviews of data 66assimilation methods used routinely in meteorology are available (e.g., Kalnay, 2003; Navon, 672009; Lahoz e Data Assimilation in Atmospheric Chemistry Models Current Status and Future Prospects for Coupled Chemistry Meteorology Modelst al., 2010). The use of data assimilation in atmospheric chemistry is more 68recent, because numerical deterministic models of atmospheric chemistryData Assimilation in Atmospheric Chemistry Models Current Status and Future Prospects for Coupled Chemistry Meteorology Models
