   Abstract:
   This study explores the complexity (or disorder) in mapping energy (R n) forcing to land surface fluxes of sensible heat (H s), water vapor (LE), and carbon dioxide (or net ecosystem exchange, NEE) for different soil water states (θ). Specifically, we ask, does the vegetation act to increase or dissipate statistical entropy injected from R n? We address this question using novel scalar complexity measures applied to a long-term time series record of R n, θ, H s, LE, and NEE collected over a uniform pine forest. This analysis is the first to demonstrate that vegetation dissipates scalar flux entropy injected through R n. We also find that the entropy or disorder in scalar fluxes increases with increasing R n and that the complexity in mapping R n to scalar fluxes is reduced with increasing θ.
