A global map of emission clumps for future monitoring of fossil fuel CO2 emissions from space

This dataset supplements the following paper submitted to ESSD:<br><b>A global map of emission clumps for future monitoring of fossil fuel CO₂ emissions from space</b><br><b><br></b>This dataset address the question of the global characterization of area and point fossil fuel CO₂ emitting sources (those hotspots are called emission clumps) that may cause coherent XCO₂ plumes in space-borne XCO₂ images. A total of 11,314 individual clumps, with 5,088 area clumps (whose indices are smaller than 100000) and 6,226 point-source clumps (whose indices are greater than or equal to 100000), are identified, based on ODIAC2017 emission map at 30×30 arc-seconds resolution. The map of emission clumps can be used by global/regional inversion systems and observing system simulation experiments (OSSEs).
