TL;DR: In this paper, a high-resolution land-atmosphere modelling system for urban CO2 emissions over the Los Angeles (LA) megacity area was presented, where the Weather Research and Forecasting (WRF)-Chem model was coupled with a very high-resolved FFCO2 emission product, Hestia-LA, to simulate atmospheric CO2 concentrations across the LA megacity at spatial resolutions as fine as ´∼´´´ 1´

TL;DR: In this paper, a comparison of a downscaled FFCO2 emission data product (Open-source Data Inventory for Anthropogenic CO2 (ODIAC)) to a bottom-up estimate (Hestia) in four U.S. urban areas was made to better isolate and understand differences between the approaches.

TL;DR: In this article, the authors used the Hestia high resolution approach to quantify FFCO2 for Salt Lake County, Utah, USA and demonstrate the importance of high resolution quantification to urban emissions mitigation policymaking.

TL;DR: Gurney et al. as discussed by the authors report on the latest urban area for which a Hestia estimate has been completed, the Los Angeles megacity, encompassing five counties: Los Angeles County, Orange County, Riverside County, San Bernardino County and Ventura County.

TL;DR: The difference in the central estimate of the two approaches comes to 0.94 MtC (an 18.7% difference) over the eight-month period between September 1, 2012 and April 30, 2013, a statistically significant difference at the 2-sigma level.
