1. Introduction Land use/land cover change is increasingly being recognized as an important yet poorly quantified component of global climate change ( Houghton et al. 2001 ). Land use/land cover change mechanisms include both transformation of natural land surfaces to those serving human needs (i.e., direct anthropogenic change; e.g., conversion of tropical forest to agriculture) as well as changes in land cover on longer time scales that are due to biogeophysical feedbacks between atmosphere

data include not only local surface forcings but the large-scale atmospheric warming signal resulting from greenhouse effects, natural decadal variability, and volcanoes ( Pielke et al. 2002 ; Kalnay and Cai 2003 ; Zhou et al. 2004 ; Frauenfeld et al. 2005 ; Lim et al. 2005 ; Kalnay et al. 2006 ). Impact of the vegetation cover can extend to some extent into the free atmosphere and thus may influence the atmospheric and surface reanalysis ( Kabat et al. 2004 ), but NNR is substantially
