TL;DR: In this article, the current state of the science to identify potential hazards currently frozen in Arctic permafrost is reviewed, including biological, chemical and radioactive materials that have been sequestered for tens to hundreds of thousands of years.

TL;DR: In this article, the authors characterized the processes controlling active-layer freezing in Arctic Alaska using an integrated approach combining in situ soil measurements, local-scale ( ∼50 m ) long-wave radar retrievals from NASA airborne P-band polarimetric SAR (PolSAR) and a remote-sensing-driven permafrost model.

TL;DR: In this paper, the authors detect and estimate decreases in CO2 emissions in Los Angeles and Washington DC/Baltimore during March and April 2020, using an inverse model to estimate relative emissions changes in 2020 compared to 2018 and 2019.

TL;DR: In this paper, the authors combine sustained observations from a network of atmospheric monitoring stations with inverse modeling to uniquely obtain spatiotemporal estimates of methane emissions from the Los Angeles megacity and the broader South Coast Air Basin for 2015-2016.

TL;DR: In this paper, the atmospheric modeling that underlies the Carbon in Arctic Reservoirs Vulnerability Experiment (CARVE) science analysis, including its meteorological and atmospheric transport components (polar variant of the Weather Research and Forecasting (WRF) and Stochastic Time Inverted Lagrangian Transport (STILT) models), is described.
