Intercomparison of techniques to model high temperature effects on CO2 and energy exchange in temperate and boreal coniferous forests

The increased frequency of high atmospheric temperatures (Ta) predicted under current climate change scenarios may adversely impact net ecosystem productivity (NEP) of temperate and boreal conifers. The ability to simulate CO2 and energy exchange under contrasting Ta and vapor pressure deficit (D) is therefore an important attribute in models used to predict climate change impacts on conifer NEP. We tested six ecosystem models differing in …
