TL;DR: In this article, an enhanced version of the SiBCASA terrestrial biosphere model is extended with biomass burning emissions from the carbon pools using remotely sensed burned area from the Global Fire Emissions Database (GFED), and an isotopic discrimination scheme that calculates 13 C signatures of photosynthesis and autotrophic respiration.

TL;DR: In this article, the authors analyzed the inter-annual variability of simulations of 21 different land surface model formulations, driven by meteorological conditions measured at 8 flux towers, located in rain forest, forest-savanna ecotone and pasture sites in Amazonia, and one in savanna site in Southeastern Brazil.

TL;DR: The seasonal cycle amplitude (SCA) of the atmosphere-ecosystem carbon dioxide (CO 2 ) exchange rate is a useful metric of the responsiveness of the terrestrial biosphere to environmental variations.

TL;DR: In this article, a new frozen biogeochemistry parameterization that separates the simulated carbon into frozen and thawed pools to represent the effects of substrate availability is described. But the parameterization does not account for substrate availability and does not work at the century to millennial timescales required to model the fate of the nearly 1100 Gt of carbon in permafrost regions.

TL;DR: In this article, a systematic review, assessment, and comparison of paleotemperature and paleohydrological proxies from the northeastern US for the last 3000 years is presented. But the comparison is limited, as the remaining paleoclimate archives in the NE US (NE US) are quite limited.
