Bo Zheng,Bo Zheng,Guannan Geng,Philippe Ciais,Steven J. Davis,Randall V. Martin,Randall V. Martin,Randall V. Martin,Jun Meng,Jun Meng,Nana Wu,Frédéric Chevallier,Grégoire Broquet,Folkert Boersma,Folkert Boersma,Ronald van der A,Ronald van der A,Jintai Lin,Dabo Guan,Yu Lei,Kebin He,Qiang Zhang +21 more
TL;DR: In this article, the authors use satellite observations together with bottom-up information to track the daily dynamics of CO2 emissions during the COVID-19 pandemic, which can provide more detailed insights into spatially explicit changes.
Journal ArticleDOI

TL;DR: In a very large population-based cohort with up to 25 y of follow-up, PM2.5 was associated with nonaccidental mortality at concentrations as low as 5 μg/m3, and the lower bound of the 95% CIs exceeded unity for all concentrations in the 1991 cohort.

TL;DR: Between January and April 2020, China’s CO2 emissions fell by 11.5% compared to the same period in 2019, but emissions have since rebounded to pre-pandemic levels before the coronavirus outbreak at the beginning of January 2020 owing to the fast economic recovery in provinces where industrial activity is concentrated.
Journal ArticleDOI
Global high-resolution emissions of soil NOx, sea salt aerosols, and biogenic volatile organic compounds.
Hongjian Weng,Jintai Lin,Randall V. Martin,Dylan B. Millet,Lyatt Jaeglé,David A. Ridley,Christoph A. Keller,Chi Li,Mingxi Du,Jun Meng +9 more
TL;DR: The HEMCO model is used to compute natural emissions of nitrogen oxides emitted from soils, sea salt aerosols, and biogenic emissions, which can be used to evaluate the impacts of resolution on estimated global and regional emissions.
Journal ArticleDOI
Estimated Long-Term (1981–2016) Concentrations of Ambient Fine Particulate Matter across North America from Chemical Transport Modeling, Satellite Remote Sensing, and Ground-Based Measurements
Jun Meng,Chi Li,Randall V. Martin,Randall V. Martin,Aaron van Donkelaar,Perry Hystad,Michael Brauer +6 more
TL;DR: Historical PM2.5 concentrations over North America from 1981 to 2016 are estimated for the first time by combining chemical transport modeling, satellite remote sensing, and ground-based measurements to assess long-term changes in exposure and associated health risks.
