M.Peñuelas, JosepStaudt, M.61 páginas, 7 figuras, 1 tabla.In models of plant volatile isoprenoid emissions, the instantaneous compound emission rate typically scales with the plant’s emission capacity under specified environmental conditions, also defined as the emission factor, ES . In the most widely employed plant isoprenoid emission models, the algorithms developed by Guenther and colleagues (1991, 1993), instantaneous variation of the steady-state emission rate is described as the product of ES and light and temperature response functions. When these models are employed in the in atmospheric chemistry modeling community, species-specific ES values and parameter values defining the instantaneous response curves are typically considered as constant. In the current review, we argue that ES is largely a modeling concept, importantly depending on our understanding of which environmental factors affect isoprenoid emissions, and consequently need standardization during ES determination. In particular, there is now increasing consensus that variations in atmospheric CO2 concentration, in addition to variations in light and temperature, need to be included in the emission models. Furthermore, we demonstrate that for less volatile isoprenoids, mono- and sesquiterpenes, the emissions are often jointly controlled by the compound synthesis and volatility, and because of these combined biochemical and physico-chemical properties, specification of ES as a constant value is incapable of describing instantaneous emissions within the sole assumptions of fluctuating light and temperature, as are used in the standard algorithms. The definition of ES also varies depending on the degree of aggregation of ES values in different parameterization schemes (leaf- vs. canopy- or region-level, species vs. plant functional type level), and various aggregated ES schemes are not compatible for different integration models. The summarized information collectively emphasizes the need to update model algorithms by including missing environmental and physico-chemical controls, and always to define ES within the proper context of model structure and spatial and temporal resolution.The authors’ work on BVOC emissions has been supported by the Estonian Ministry of Education and Research (grant SF1090065s07), the Estonian Science Foundation (grant 7645), the US National Science Foundation and the US Environmental Protection Agency, the join collaborative project between Spanish CSIC and the Estonian Academy of Sciences, the Spanish Government (grants CGL2006-04025/BOS and Consolider-Ingenio BGD 7, 1233–1293, 2010 The emission factor of volatile isoprenoids U.
