Mountains are vital ecosystems, yet predicting plant growth there is complex due to diverse microclimates on slopes. Equatorial-facing slopes (EFSs) are drier and warmer, and polar-facing slopes (PFSs) are wetter and colder, than their regional macroclimates. [...]

13 p, 1.2 MB Simple Models Outperform More Complex Big-Leaf Models of Daily Transpiration in Forested Biomes / Bright, Ryan M. (Norwegian Institute of Bioeconomy Research) ; Miralles, Diego G. (Ghent University. Department of the Environment) ; Poyatos, Rafael (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Eisner, Stephanie (Norwegian Institute of Bioeconomy Research)
Transpiration makes up the bulk of total evaporation in forested environments yet remains challenging to predict at landscape-to-global scales. We harnessed independent estimates of daily transpiration derived from co-located sap flow and eddy-covariance measurement systems and applied the triple collocation technique to evaluate predictions from big leaf models requiring no calibration.

The accurate estimation of photosynthetic phenology using vegetation indices (VIs) is important for measuring the interannual variation of atmospheric CO2 concentrations, but the relative performances of structural and physiological VIs remain unclear. [...]

The large peatland carbon stocks in the land use change-affected areas of equatorial Asia are vulnerable to fire. Combining satellite observations of active fire, burned area, and atmospheric concentrations of combustion tracers with a Bayesian inversion, we estimated the amount and variability of fire carbon emissions in equatorial Asia over the period 1997-2015.

5 p, 851.5 KB Instrumental validation of Globigerinoides ruber Mg/Ca as a proxy for NE Pacific summer SST / Mortyn, P. Graham (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Herguera, Juan Carlos (Centro de Investigación Científica y Educación Superior de Ensenada. Departamento de Oceanografía) ; Martínez Botí, M. A. (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals)
Accurate reconstruction of sea surface temperature (SST) is a high research priority, given that it is such a crucial variable in the Earth's climate system. The Mg/Ca composition of Globigerinoides ruber (white) has been calibrated and applied for a number of tropical and extratropical paleo-SST reconstructions, though validation studies of the proxy against instrumental observations are relatively scarce.
