| Summary: | The Open-source Data Inventory for Anthropogenic CO<sub>2</sub> (ODIAC) is a
global high-spatial-resolution gridded emissions data product that
distributes carbon dioxide (CO<sub>2</sub>) emissions from fossil fuel combustion.
The emissions spatial distributions are estimated at a 1 × 1 km
spatial resolution over land using power plant profiles (emissions intensity
and geographical location) and satellite-observed nighttime lights. This
paper describes the year 2016 version of the ODIAC emissions data product
(ODIAC2016) and presents analyses that help guide data users, especially
for atmospheric CO<sub>2</sub> tracer transport simulations and flux inversion
analysis. Since the original publication in 2011, we have made modifications
to our emissions modeling framework in order to deliver a comprehensive
global gridded emissions data product. Major changes from the 2011
publication are (1) the use of emissions estimates made by the Carbon Dioxide
Information Analysis Center (CDIAC) at the Oak Ridge National Laboratory
(ORNL) by fuel type (solid, liquid, gas, cement manufacturing, gas flaring,
and international aviation and marine bunkers); (2) the use of multiple
spatial emissions proxies by fuel type such as (a) nighttime light data specific to
gas flaring and (b) ship/aircraft fleet tracks; and (3) the inclusion of emissions
temporal variations. Using global fuel consumption data, we extrapolated the
CDIAC emissions estimates for the recent years and produced the ODIAC2016
emissions data product that covers 2000–2015. Our emissions data can be viewed
as an extended version of CDIAC gridded emissions data product, which should
allow data users to impose global fossil fuel emissions in a more
comprehensive manner than the original CDIAC product. Our new emissions modeling
framework allows us to produce future versions of the ODIAC emissions data
product with a timely update. Such capability has become more significant
given the CDIAC/ORNL's shutdown. The ODIAC data product could play an important
role in supporting carbon cycle science, especially modeling studies with
space-based CO<sub>2</sub> data collected in near real time by ongoing carbon
observing missions such as the Japanese Greenhouse gases Observing SATellite (GOSAT),
NASA's Orbiting Carbon Observatory-2 (OCO-2), and upcoming future missions.
