Hourly fossil-fuel CO₂ released across the US (2010-2015)

Vulcan: High-Resolution Hourly Fossil Fuel CO2 Emissions in USA, 2010-2015, Version 3
atmosphere NASA ORNL_CLOUD Level 4 netCDF-4 classic
In plain English

What it measures. Hour-by-hour estimates of carbon dioxide released from burning fossil fuels and making cement across the United States, broken down by source like cars, power plants, homes, factories, ships, and airports.

How it's made. Not a satellite product; it's a model that adds up emissions from the ground up onto a fine 1-km map for every hour from 2010 to 2015.

How & where you'd use it. Helps scientists model how CO2 moves through the air, and supports climate policy, mapping, and analysis of where emissions actually come from.

Official description

The Vulcan version 3.0 hourly dataset quantifies hourly emissions at a 1-km resolution for the 2010-2015 time period. Estimates are provided of hourly carbon dioxide (CO2) emissions from the combustion of fossil fuels (FF) and CO2 emissions from cement production for the conterminous United States and the state of Alaska. Referred to as FFCO2, the emissions from Vulcan are categorized into 10 source sectors including; residential, commercial, industrial, electricity production, onroad, nonroad, commercial marine vessel, airport, rail, and cement. Files for hourly total emissions are also available. Data are represented in space on a 1 km x 1 km grid as hourly totals for 2010-2015. This dataset provides the first bottom-up U.S.-wide FFCO2 emissions data product at 1 km2/hourly for multiple years and is designed to be used as emission estimates in atmospheric transport modeling, policy, mapping, and other data analyses and applications.
