TL;DR: The global land-based CO2 sink can be derived from the difference between fossil fuel emissions and the sum of estimated increases of CO2 in the atmosphere and in the ocean.

TL;DR: Mcire et al. as mentioned in this paper compared analyses of carbon exchange of Arctic tundra between observations, regional and global applications of process-based terrestrial biosphere models, and atmospheric inversion models.

TL;DR: The development and deployment of the Osprey UAS, as a state-of-the-art methodology, has the potential to be widely used for characterizing tundra vegetation composition and canopy properties to improve the understanding of ecosystem dynamics in the Arctic, and to address scale issues between ground-based and airborne/satellite observations.

TL;DR: This paper examined natural and anthropogenic controls on terrestrial evapotranspiration (ET) changes from 1982 to 2010 using multiple estimates from remote sensing-based datasets and process-oriented land surface models.

TL;DR: In this article, the authors looked at existing simulation results from two different modeling approaches (Global Fire Emissions Database version 4 [GFED4s] and Terrestrial Ecosystem Model version 6 [TEM6]) that used global area burned data to provide recent, retrospective estimates of CO2 emissions from vegetation combustion, together with published, biomeand continental-scale conversion ratios that relate CO 2 emissions to PyC production (PyC/CO2) in combustion.
