TL;DR: It is found that tundra ecosystems were a net source of CO2 to the atmosphere annually, with especially high rates of respiration during early winter (October through December), providing evidence that the decadal-scale increase in the amplitude of the CO2 seasonal cycle may be linked with increasing biogenic emissions in the Arctic, following the growing season.

TL;DR: In this article, the authors used satellite retrievals and surface observations of atmospheric methane to suggest that U.S. anthropogenic methane emissions have increased by more than 30% over the 2002-2014 period.

TL;DR: In this paper, satellite observations of solar-induced chlorophyll fluorescence (SIF) provide a more direct proxy for photosynthesis, instead of EVI, for modeling the seasonal cycle of tundra photosynthesis.

TL;DR: In this article, the authors simulate atmospheric methane over a generic oil/gas field (20-500 production sites of different size categories in a 50×50 ˚km 2 domain) for a 1-week period using the WRF-STILT meteorological model.

TL;DR: In this paper, the authors investigate Arctic tropospheric composition using ground-based Fourier transform infrared (FTIR) solar absorption spectra, recorded at the Polar Environment Atmospheric Research Laboratory (PEARL, Eureka, Nunavut, Canada, 80°05' N, 86°42' W) and at Thule (Greenland, 76°53" N, −68°74' W).
