Comparison of CO2 inversion products

The Atmospheric Tracer Transport Model Intercomparison Project (Transcom) was created to quantify and diagnose the uncertainty in inversion calculations of the global carbon budget that result from errors in simulated atmospheric transport. TransCom was conceived at the Fourth International CO2 Conference in Carqueiranne in 1993.

For further details on this project, please see

The goal of this site is to show some results from different contributors inverse systems of the transcom community:
