Global fire emissions and the contribution of deforestation, savanna, forest, agricultural, and peat fires (1997-2009)
Abstract. New burned area datasets and top-down constraints from atmospheric concentration measurements of pyrogenic gases have decreased the large uncertainty in fire emissions estimates. However,…
Physiological and environmental regulation of stomatal conductance, photosynthesis and transpiration: a model that includes a laminar boundary layer
Abstract This paper presents a system of models for the simulation of gas and energy exchange of a leaf of a C3 plant in free air. The physiological processes are simulated by sub-models that: (a)…
A Revised Land Surface Parameterization (SiB2) for Atmospheric GCMS. Part I: Model Formulation
Abstract The formulation of a revised land surface parameterization for use within atmospheric general circulation models (GCMs) is presented. The model (SiB2) incorporates several significant…
A Revised Land Surface Parameterization (SiB2) for Atmospheric GCMS. Part II: The Generation of Global Fields of Terrestrial Biophysical Parameters from Satellite Data
Abstract The global parameter fields used in the revised Simple Biosphere Model (SiB2) of Sellers et al. are reviewed. The most important innovation over the earlier SiB1 parameter set of Dorman and…
Coupled Photosynthesis-Stomatal Conductance Model for Leaves of C4 Plants
TLDR
A simple model for predicting An and g from leaves of C4 plants that is easily parameterised and that predicts many of the important environmental responses is developed and shown to be highly correlated with the data.
Interannual variability in global biomass burning emissions from 1997 to 2004
Biomass burning represents an important source of atmospheric aerosols and greenhouse gases, yet little is known about its interannual variability or the underlying mechanisms regulating this…
Global fire emissions estimates during 1997–2016
Abstract. Climate, land use, and other anthropogenic and natural drivers have the potential to influence fire dynamics in many regions. To develop a mechanistic understanding of the changing role of…
Assessing variability and long-term trends in burned area by merging multiple satellite fire products
Abstract. Long term, high quality estimates of burned area are needed for improving both prognostic and diagnostic fire emissions models and for assessing feedbacks between fire and the climate…
Global estimation of burned area using MODIS active fire observations
We present a method for estimating monthly burned area globally at 1 spatial resolution using Terra MODIS data and ancillary vegetation cover information. Us- ing regression trees constructed for 14…
CO 2 emissions from forest loss
Deforestation is the second largest anthropogenic source of carbon dioxide to the atmosphere, after fossil fuel combustion. Following a budget reanalysis, the contribution from deforestation is…
