TL;DR: The Sensor-web Operations Explorer (SOX) research task under the NASA Earth Science Technology Office addresses challenges by creating a virtual sensor-web experiment framework that can support orbital and sub-orbital observation system simulation experiment.

TL;DR: In this article , the temporal variability in the surface concentrations from February 2015 to April 2022 was studied to detect a declining trend in methane emissions in the Los Angeles basin, and the authors quantified the reduction due to this declining trend through inverse modeling and showed that methane emissions have declined by 15 Gg, or ∼7% over five years from January 2015 to May 2020.

TL;DR: In this paper , a harmonized data set synthesizing urban GHG observations from cities with monitoring networks across North America is presented to facilitate cross-city analyses and address scientific questions that are difficult to address in isolation.

TL;DR: In this article, a sensor-web system is proposed to observe trace gases, aerosols, clouds, and physical parameters, an integrated observation infrastructure composed of space-borne, air-borne and in-situ sensors will be simulated based on their measurement physics properties, the sampling strategies will be explored and science impact will be analyzed based on comprehensive modeling of atmospheric phenomena including convection, transport and chemical process.
