TLDR
This paper found that freeze-thaw events are responsible for 17 to 28% of nitrous oxide emitted from agricultural soils globally. But they did not consider the effect of weather conditions.Abstract:
Large fluxes of nitrous oxide occur when frozen soils thaw. Field measurements and mathematical models suggest that freeze–thaw events are responsible for 17 to 28% of nitrous oxide emitted from agricultural soils globally.read more

TL;DR: A global N2O inventory is presented that incorporates both natural and anthropogenic sources and accounts for the interaction between nitrogen additions and the biochemical processes that control N 2O emissions, using bottom-up, top-down and process-based model approaches.

TL;DR: This study assessed the effects of multiple anthropogenic and natural factors, including nitrogen fertilizer application, atmospheric N deposition, manure N application, land cover change, climate change, and rising atmospheric CO2 concentration on global soil N2 O emissions for the period 1861-2016 using a standard simulation protocol with seven process-based terrestrial biosphere models.

TL;DR: High-resolution atmospheric inverse analyses reveal that direct and indirect N2O emissions from the US Corn Belt are highly sensitive to perturbations in temperature and precipitation, and project a strong positive feedback to warmer and wetter conditions and unabated growth of regional N 2O emissions that will exceed 600 Gg N2 O-N⋅y−1, on average, by 2050.

TL;DR: It is reported that the Arctic may become a substantial source of N2O when the permafrost thaws, and that N2 O emissions could occur from surfaces covering almost one-fourth of the entire Arctic.
Journal ArticleDOI
Nitrous oxide emissions and biogeochemical responses to soil freezing-thawing and drying-wetting
TL;DR: In this article, the authors identify the similarities and differences in the mechanisms which lead to potentially higher N2O fluxes during FT compared to DW cycles and identify strategic research areas required for improving the understanding of FT and DW processes leading to emissions.

TL;DR: The Modern-Era Retrospective Analysis for Research and Applications (MERRA) was undertaken by NASA's Global Modeling and Assimilation Office with two primary objectives: to place observations from NASA's Earth Observing System satellites into a climate context and to improve upon the hydrologic cycle represented in earlier generations of reanalyses as mentioned in this paper.

TL;DR: The Global Land Data Assimilation System (GLDAS) as mentioned in this paper is an uncoupled land surface modeling system that drives multiple models, integrates a huge quantity of observation-based data, runs globally at high resolution (0.25°), and produces results in near-real time (typically within 48 h of the present).
