Mauna Loa and South Pole Difference with Fossil Fuel


Description

Black Dots: Difference of the seasonally adjusted monthly average atmospheric carbon dioxide concentration at Mauna Loa Observatory, Hawaii and South Pole, Antarctica versus time where CO2 concentration is in parts per million in the mole fraction (p.p.m.).

Black Curve: Spline fit to the CO2 data.

Red Curve: Fit to the CO2 data in the form of A + B·FF where A and B are constants that are adjusted to optimally fit the data and where FF is the global fossil fuel emissions in PgCyr-1. The values of the constants are A = -0.82 ppm CO2 and B = 0.513 ppm CO2/(PgCyr-1).

Data from Scripps CO2 Program.


Data sharing policy

The data and graphics on this website are made freely available, with the understanding that appropriate credit will be given. For applications supporting peer-reviewed scientific publications, coauthorship may sometimes be appropriate. An example would be if an important result or conclusion depends on this product, such as the first account of a previously unreported phenomenon. Ethical usage requires disclosing intentions at early stages of the work in order to avoid duplicating ongoing studies at Scripps. For applications where coauthorship is not needed, which includes all applications outside of the peer-reviewed scientific literature, it is sufficient to acknowledge the Scripps CO2 program as the source.
