FFDAS is a data product that estimates CO2 emissions from the combustion of fossil fuel for the years 1997 to 2011 on a global, 0.1° × 0.1°, hourly grid.

This data product is the result of a collaboration between Arizona State University (Drs. Kevin Robert Gurney & Salvi Asefi-Najafabady), the University of Melbourne (Dr. Peter Rayner) and Purdue University (Dr. Bedrich Benes). We are currently providing retrieval and visualization of FFDAS version 2.0.

The methodology used to generate FFDAS can be found in Rayner et al. (2010) and Asefi-Najafabady et al. (2014). In short, the FFDAS estimates fossil fuel CO2 emissions by constraining elements of the Kaya identity at the gridcell level with national statistics on fossil fuel CO2 emissions, remotely sensed nighttime lights, population data, and information on the world’s power plants.
