Study Area: (All latitudes and longitudes given in decimal degrees) Temporal Coverage: The data cover the period to Spatial Coverage: Conterminous United States This project was funded by NASA’s Interdisciplinary Science (IDS) and Carbon Monitoring System (CMS) programs, and NOAA’s Atmospheric Chemistry Carbon Cycle and Climate program under the CO2-Urban Synthesis and Analysis (CO2-USA) project. CMS: CO2 Emissions from Fossil Fuels Combustion, ACES Inventory for Northeastern USA. CMS will maintain a global emphasis while providing finer scale regional information, utilizing space-based and surface-based data and will rapidly initiate generation and distribution of products both for user evaluation and to inform near-term policy development and planning.

The System will use the full range of NASA satellite observations and modeling/analysis capabilities to establish the accuracy, quantitative uncertainties, and utility of products for supporting national and international policy, regulatory, and management activities. The NASA Carbon Monitoring System (CMS) is designed to make significant contributions in characterizing, quantifying, understanding, and predicting the evolution of global carbon sources and sinks through improved monitoring of carbon stocks and fluxes. Vehicle emissions were estimated directly at the scale of individual road segments without the need to downsize emissions using spatial predictors. This approach helped to refine the uncertainty in the spatial distribution of road vehicle emissions and showed the highly nonlinear relationship between population density and emissions.

A GeoDatabase file containing all years of data is also included.ĭARTE is the first nationally consistent inventory of US on-road CO2 emissions built from bottom-up source activity data and establishes a national benchmark for monitoring, reporting, and verification of emissions that are vital for regulating greenhouse gases. The DARTE data provides insights into how urban areas contribute to climate change.ĭARTE combined the Federal Highway Administration's (FHWA's) Highway Performance Monitoring System (HPMS) roadway-level vehicle miles traveled with year- and state-specific emissions factors for five vehicle types on six classes of urban and rural roads. Each GeoTIFF file is a separate year of CO2 emission estimates. Inventories are provided in 38 individual GeoTIFF files with 1-km spatial resolution.

CO2 emissions from the on-road transportation sector are provided annually for 1980-2017 as a continuous surface at a spatial resolution of 1 km.ĭARTE is the first nationally consistent inventory of US on-road CO2 emissions built from bottom-up source activity data and establishes a national benchmark for monitoring, reporting, and verification of emissions that are vital for regulating greenhouse gases. This data set provides a 38-year, 1-km resolution inventory of annual on-road CO2 emissions for the conterminous United States based on roadway-level vehicle traffic data and state-specific emissions factors for multiple vehicle types on urban and rural roads as compiled in the Database of Road Transportation Emissions (DARTE).
