Global expansion of wildland-urban interface (WUI) and WUI fires
Fires in the wildland-urban interface (WUI) are an important issue globally. To understand the change of WUI, we develop a 9 km worldwide unified wildland-urban interface database for 2001–2020 with Random Forest models and satellite data. We find that WUI has been increasing in all populated continents from 2001 to 2020 and the global relative increase is 24%, with the largest relative increase (∼59%) over Africa. Global total fire counts decrea…
The International Global Atmospheric Chemistry project comments on the revised WHO air quality guidelines
In September 2021, the World Health Organization (WHO) announced updated global air quality guidelines providing health-based targets for six key air pollutants [1]. The annual targets for pollutant concentrations were reduced fourfold for nitrogen dioxide (NO2) to 10 μg m−3 and by 50% and 25% respectively for the mass concentration of particles smaller than and equal to 2.5 μm (PM2.5) and 10 μm (PM10) to 5 μg m−3 and 15 μg m−3. New targets were …
Multi-model intercomparisons of air quality simulations for the Korus-AQ campaign
The Korea-United States Air Quality (KORUS-AQ) field study was conducted during May–June 2016 to understand the factors controlling air quality in South Korea. Extensive aircraft and ground network observations from the campaign offer an opportunity to address issues in current air quality models and reduce model-observation disagreements. This study examines these issues using model evaluation against the KORUS-AQ observations and intercompariso…
The Korea–United States Air Quality (Korus-AQ) field study
The Korea-United States Air Quality (KORUS-AQ) field study was conducted during May-June 2016. The effort was jointly sponsored by the National Institute of Environmental Research of South Korea and the National Aeronautics and Space Administration of the United States. KORUS-AQ offered an unprecedented, multi-perspective view of air quality conditions in South Korea by employing observations from three aircraft, an extensive ground-based network…
The Community Earth System Model Version 2 (Cesm2)
An overview of the Community Earth System Model Version 2 (CESM2) is provided, including a discussion of the challenges encountered during its development and how they were addressed. In addition, an evaluation of a pair of CESM2 long preindustrial control and historical ensemble simulations is presented. These simulations were performed using the nominal 1° horizontal resolution configuration of the coupled model with both the “low‐top” (40 km, …
Characterization, sources and reactivity of volatile organic compounds (VOCs) in Seoul and surrounding regions during Korus-AQ
The Korea-United States Air Quality Study (KORUS-AQ) took place in spring 2016 to better understand air pollution in Korea. In support of KORUS-AQ, 2554 whole air samples (WAS) were collected aboard the NASA DC-8 research aircraft and analyzed for 82 C1–C10 volatile organic compounds (VOCs) using multi-column gas chromatography. Together with fast-response measurements from other groups, the air samples were used to characterize the VOC compositi…
Evaluating ethane and methane emissions associated with the development of oil and natural gas extraction in North America
Sharp rises in the atmospheric abundance of ethane (C 2 H 6 ) have been detected from 2009 onwards in the Northern Hemisphere as a result of the unprecedented growth in the exploitation of shale gas and tight oil reservoirs in North America. Using time series of C 2 H 6 total columns derived from groundbased Fourier transform infrared (FTIR) observations made at five selected Network for the Detection of Atmospheric Composition Change sites, we c…
The Model of Emissions of Gases and Aerosols from Nature version 2.1 (Megan2.1)
The Model of Emissions of Gases and Aerosols from Nature version 2.1 (MEGAN2.1) is a modeling framework for estimating fluxes of biogenic compounds between terrestrial ecosystems and the atmosphere using simple mechanistic algorithms to account for the major known processes controlling biogenic emissions. It is available as an offline code and has also been coupled into land surface and atmospheric chemistry models. MEGAN2.1 is an update from the…
